view from the sensor is obstructed by another vehicle. This type of occlusion results in
the vehicle not being detected by the sensor.
Or
When a vehicle in one lane passes through the detection zone of an adjacent lane. This
type of occlusion can result in the same vehicle being counted in more than one lane.
I. Detection Zone. The detection zone is a line or area selected through the VIVDS
processor unit that when occupied by a vehicle, sends a vehicle detection to the traffic
controller or freeway management system.
J. Detection Accuracy. The measure of the basic operation of a detection system (shows
detection when a vehicle is in the detection zone and shows no detection when there is
not a vehicle in the detection zone).
K. Live Video. Video being viewed or processed at 30 frames per second.
L. Lux. The measure of light intensity at which a camera may operate. A unit of
illumination equal to one lumen per square meter or to the illumination of a surface
uniformly one meter distant from a point source of one candle.
M. Video Monitor. As a minimum must be a 9-in. black and white monitor with BNC
connectors for video in and out.
3. Functional Capabilities.

zones within the combined field of view of all cameras (a minimum of 12 detection zones
per camera input to the VIVDS processor unit).
Detection zones must be provided that are sensitive to the direction of vehicle travel. The
direction to be detected by each detection zone must be user programmable.
The VIVDS processor unit must compensate for minor camera movement (up to 2% of the
field of view at 400 ft.) without falsely detecting vehicles. The camera movement must be
measured on the unprocessed video input to the VIVDS processor unit.
The camera must operate while directly connected to VIVDS Processor Unit.
Once the detector configuration has been downloaded or saved into the VIVDS processor
unit, the video detection system must operate with the monitoring equipment (monitor
and/or laptop) disconnected or on-line.
When the monitoring equipment is directly connected to the VIVDS processor unit, it must
be possible to view vehicle detections in real time as they occur on the field setup
computer's color VGA display or the video monitor.
4. Vehicle Detection.
A. Detection Zone Placement. The video detection system must provide flexible detection
zone placement anywhere within the combined field of view of the image sensors.
Preferred presence detector configurations must be lines or boxes placed across lanes of
traffic or lines placed in line with lanes of traffic. A single detector must be able to
replace one or more conventional detector loops. Detection zones must be able to be
fully overlapped. In addition, detection zones must have the capability of implementing
“AND” and “OR” logical functions including presence, extension and delay timing.
These logical functions may be excluded if provisions are made to bring each detector
separately into the controller and the controller can provide these functions.
B. Detection Zone Programming. Placement of detection zones must be by means of a
graphical interface using the video image of the roadway. The monitor must show
images of the detection zones superimposed on the video image of traffic while the
VIVDS processor is running.
The detection zones must be created by using the mouse or keypad to draw detection
zones on the monitor. The detection zones must be capable of being sized, shaped and
overlapped to provide optimal road coverage and detection. It must be possible to
upload detector configurations to the VIVDS processor unit and to retrieve the detector
configuration that is currently running in the VIVDS processor unit.
The mouse or keypad must be used to edit previously defined detector configurations so
as to fine tune the detection zone placement size and shape. Once a detection
configuration has been created, the system must provide a graphic display of the new
configuration on its monitor. While this fine-tuning is being done, the detection must
continue to operate from the detector configuration that is currently called.
3-10 6266
09-05
When a vehicle occupies a detection zone, the detection zone on the live video must
indicate the presence of a vehicle, thereby verifying proper operation of the detection
system. With the absence of video, the card must have an LED that will indicate proper
operation of the detection zones.
Detection zones must be provided that is sensitive to the direction of vehicle travel. The
direction to be detected by each detection zone must be user programmable. The vehicle
detection zone should not activate if a vehicle traveling any direction other than the one
specified for detection occupies the detection zone. Cross-street and wrong way traffic
should not cause a detection.
C. Design Field of View. The video detection system must reliably detect vehicle presence
in the design field of view. The design field of view must be defined as the sensor view
when the image sensor is mounted 24 ft. or higher above the roadway, when the camera
is adjacent (within 15 ft.) to the edge of the nearest vehicle travel lane, and when the
length of the detection area is not greater than 10 times the mounting height of the
image sensor. Within this design field of view, the VIVDS processor unit must be
capable of setting up a single detection zone for point detection (equivalent to the
operation of a 6 ft. by 6 ft. inductive loop). A single camera, placed at the proper
mounting height with the proper lens, must be able to monitor up to and including 5
traffic lanes simultaneously.
D. Detection Performance. Detection accuracy of the video detection system must be
comparable to properly operating inductive loops. Detection accuracy must include the
presence of any vehicle in the defined detection zone regardless of the lane, which the
vehicle is occupying. Occlusion produced by vehicles in the same or adjacent lanes
must not be considered a failure of the VIVDS processor unit, but a limitation of the
camera placement. Detection accuracy (a minimum of 95%) must be enforced for the
entire design field of view on a lane by lane and on a time period basis. When specified
in the plans, furnish up to 24 continuous hours of recorded video of all installed
intersection cameras within the 30 day test period for verification of proper camera
placement, field of view, focus, detection zone placement, processor setup and
operation. The video from each camera must show vehicle detections for all zones.
E. Equipment failure, either camera or VIVDS processor unit, must result in constant
vehicle detection on affected detection zones.

Determine the plasticity index using Tex-106-E if the decantation value exceeds 5%. The
decantation and plasticity index requirements do not apply to RAP samples with asphalt removed
by extraction.
Do not intermingle Contractor-owned RAP stockpiles with Department-owned RAP
stockpiles. Remove unused Contractor-owned RAP material from the project site upon
completion of the project. Return unused Department-owned RAP to the designated stockpile
location.

Article 340.2. Materials, Section A. Aggregate. is supplemented by the following:

4. Recycled Asphalt Shingles (RAS). The contractor may use post-manufactured RAS or post-
consumer RAS; however, the use of post-consumer RAS may be restricted when shown on
the plans. RAS are defined as processed asphalt shingle material from manufacturing of
asphalt roofing shingles or from re-roofing residential structures. “Post-manufactured RAS”
are processed manufacturer’s shingle scrap by-product. “Post-consumer RAS,” or “tear-offs,”
are processed shingle scrap removed from residential structures.

Process the RAS by ambient grinding or granulating such that 100% of the particles pass the
1/2 in. sieve when tested in accordance with Tex-200-F, Part I. Add sand meeting the
requirements of Table 1 and Table 2 to RAS stockpiles, if needed, to keep the processed
material workable. Use a maximum of 4% sand by weight of RAS. Perform a sieve analysis
on processed RAS material prior to extraction of the asphalt.

Determine asphalt content and gradation of the RAS material for mixture design purposes in
accordance with Tex-236-F. Unless otherwise shown on the plans, use no more than 5%
processed RAS of the total mixture weight. When RAS is used, whether in conjunction with
RAP or not, calculate and ensure the ratio of the virgin binder to total binder is greater than
65% in surface mixtures and 60% in non-surface mixtures. “Surface” mixtures are defined as
mixtures that will be final lifts or riding surfaces of a pavement structure. “Non-Surface”
mixtures are defined as mixtures that will be intermediate or base layers in a pavement
structure. When RAS is used in conjunction with fractionated RAP, use no more than 20%

proposed to be slipformed, tie all bar intersections. Provide a wire line to maintain vertical and
horizontal alignment of the slipform machine. Attach a grade line gauge or pointer to the
machine so a continuous comparison can be made between the rail being placed and the
established grade line. Rails or supports at the required grade are allowed instead of sensor
controls. Prior to placing concrete, make one or more passes with the slipform over the rail
segment to ensure proper operation and maintenance of grades and clearances. Provide
slipformed rail within a vertical and horizontal alignment tolerance of +/- ¼ in. in 10 ft.
Construct rail with a smooth and uniform appearance. Consolidate concrete so it is free of
honeycomb. Provide concrete with a consistency that will maintain the shape of the rail without
support. Minimize starting and stopping of the slipform operation by ensuring a continuous
supply of concrete.

pavers are to be installed using the mortar set method, also remove additional items from
concrete substrates that could impair mortar bond, including curing compounds, sealing
compounds, form oil and laitance.
3.3 INSTALLATION, GENERAL
A. Do not use unit pavers with chips, cracks, voids, discolorations, or other defects that might be
visible or cause staining in finished work.
B. Mix pavers from several pallets or cubes, as they are placed, to produce uniform blend of colors
and textures.
C. Handle protective-coated brick pavers to prevent coated surfaces from contacting backs or
edges of other units. If, despite these precautions, coating does contact bonding surfaces of
brick, remove coating from bonding surfaces before setting brick.
D. J oint Pattern: Reference the drawings.
E. Tolerances:
1. If slopes are 1 1/2 per cent or less, do not exceed 1/32-inch unit-to-unit offset from flush
(lippage) nor 1/8 inch in 10 feet from level, or indicated slope, for finished surface of
paving.
2. If slopes are 1 ¼ per cent or greater do not exceed 1/16 inch unit to unit offset from flush
(lippage) nor 1/8 inch in 2 feet or ¼ inch in 10 feet from level or indicated slope for finish
surface of paving.
F. Provide edge restraints as indicated. Install edge restraints before placing unit pavers.
1. For metal edge restraints with top edge exposed, install at ¾ to 1 inch maximum below
top edge.
2. Where pavers set in mortar bed are indicated as edge restraints for pavers set in
aggregate setting bed, install pavers set in mortar and allow mortar to cure before placing
aggregate setting bed and remainder of pavers. Cut off mortar bed at a steep angle so it
will not interfere with aggregate setting bed and strike non-paver side flush.
3.4 CONSTRUCTION OF THE SAND SETTING BED:
A. The uncompacted sand leveling course shall be spread evenly over the area to be paved and
then screeded to a level that will produce from one (1") inch to 1 ½ inch maximum thickness
when the paving stones have been placed and vibrated.
B. Plan work such that the final elevation of paving stones is approximately 1/8 inch higher than
adjacent paving to allow for minor setting that may occur within the sand base during vibrating
procedures, especially allow distance for traffic conditions.
C. Once screeded and leveled to the desired elevation, this sand leveling course shall not be
disturbed in any way.
3.5 LAYING PAVERS:
A. Install one edge of the edge restraint. Using a ‘starter run’ of pavers, establish the actual width
of the area to receive pavers.
1. Unless otherwise noted on the plans, all walks are to be constructed to full paver
dimensions.
2. Contractor may provide minor adjustment and arrange the steel edge restraint such that
its location allows minor field modifications and does permit the use of whole pavers.

minor cuts accomplished with diamond blade saws and grinders.
2. Cuts should result with a paver less than one-third (1/3) of original dimension.
3. Provide necessary safety equipment and dust masks when cutting pavers.
E. Vibrate pavers into the sand laying course using a vibrator capable of 3,000 to 5,000 pounds
compaction force wat 80 to 90 Hz. Use vibrator with neoprene mat on the face of the plate or
means as needed to prevent damage, chipping or cracks in the surface pavers
1. Perform a minimum of three passes across the paving with the vibrator.
F. Compact pavers when there is sufficient surface to accommodate operation of vibrator, leaving
at least 36 inches of uncompacted pavers adjacent to temporary edges.
1. Before ending each day's work, compact installed concrete pavers except for 36-inch
width of uncompacted pavers adjacent to temporary edges (laying faces).
2. As work progresses to perimeter of installation, compact installed pavers that are
adjacent to permanent edges unless they are within 36 inches of laying face.
3. Before ending each day's work and when rain interrupts work, cover pavers that have not
been compacted and cover leveling course on which pavers have not been placed with
non-staining plastic sheets to protect them from rain.
G. Unless joint stabilization is required proceed with filling joints and vibrating as follows. If joint
stabilization is required, proceed with installing mixed stabilizers with sand as noted in Articles
below.
1. After vibration, spread dry sand or spread slightly damp sand and allow it to dry. Proceed
after drying and fill joints immediately after vibrating pavers into leveling course. Vibrate
pavers and add sand until joints are completely filled, then remove excess sand.
2. Surplus material shall then be swept from the surface or left on surface during
construction time to insure complete filling of joints during initial use at the option of the
Owner and General Contractor.
H. Do not allow traffic on installed pavers until sand has been vibrated into joints.
I. Repeat joint-filling process as a condition of the maintenance period at 30 days after installation.
3.6 MORTAR SETTING-BED APPLICATIONS
A. Saturate concrete subbase with clean water several hours before placing setting bed. Remove
surface water about one hour before placing setting bed.
B. Apply mortar-bed bond coat over surface of concrete subbase about 15 minutes before placing
mortar bed. Limit area of bond coat to avoid its drying out before placing setting bed. Do not
exceed 1/16-inch thickness for bond coat.
C. Apply mortar bed over bond coat; spread and screed mortar bed to uniform thickness at
subgrade elevations required for accurate setting of pavers to finished grades indicated.

performed and pavers are cleaned as outlined in previous portions of this Section verify
that all pavement has been compacted and that all joints are completely filled with sand.
a. Great care shall be taken to ensure that the joints are filled to the bottom of the
chamfer or 1/8 inch below the finished surface of the pavement when there are no
chamfers.
2. The surface shall be clean and free from any staining, oil, dust and any loose material
prior to the application of joint sand stabilizer. The surface of the paver and the joint sand
should be dry for its full depth prior to commencing work.
3. The joint sand stabilizer shall be applied evenly using an electrical sump pump delivering
not more than 5 gallons per minute. The pump should be fitted with a 3 foot long ¾ inch
inlet hose placed in the pail or drum of sealer and a 30 foot ¾ inch outlet hose fitted with
a trigger action spray nozzle to discharge the material on to the pavement. The operator
must flood the pavement working in one direction assisted by two operators who should
work the excess material into the sand joints using 24 inch rubber floor squeegees,
ensuring that all joints are adequately flooded and that no surplus material is left on the
surface. The joints should be re-flooded as necessary during the application process to
achieve binding of the sand to a depth of at least 1/2”.
B. The treated area should be protected from rain or moisture and not be trafficked for 24 hours
after completing the application of the stabilizer. Work shall cease if inclement weather (rain or

strong wind) will affect the stabilizing operation and shall not recommence until the joint sand
has dried sufficiently to allow penetration of the stabilizer / sealant.
3.9 CLEAN UP:
A. Keep all areas of work clean, neat and orderly at all times.
B. Confirm cleaning of stains on pavers with the manufacturer.
1. Generally, if the pavement has been stained, cleaning should be carried out with high-
pressure washing equipment delivering water at a temperature not exceeding 220
degrees F with fan shaped spray nozzles at pressures not exceeding 2,500 psi after
applying non-citric based de-greasers and detergents.
2. The nozzle shall be directed at the pavers from a height of 2 feet and at an angle of 45
degrees.
3. Care should be taken to prevent the jets from being directed into the joints so as not to
dislodge the joint sand as far as possible
C. Upon completion of work under this Section, Contractor shall remove from the premises all
surplus materials, tools, equipment, rubbish and debris resulting from the Work at his own
expense.
