Wisconsin WisDOT Standard Specifications (within FDM) — Section 648

Effective with the December 2018 Letting 459 2019 Standard Spec ifications Section 648 Locating No-passing Zones

648.1Description

(1)This section describes locati ng and marking both ends of no-pa ssing zones on the pavement surface

independently from existing no-passing zones.

648.2Materials

(1)Furnish paint that will be read ily visible unt il no-passing ba rrier lines are placed. Use white on asphalt

and black on concrete. 648.3 Construction 648.3.1 Equipment

(1)Furnish two vehicles equipped wi th two-way communications equi pment, full-width flashing yellow light

bars with 360 degree visibility, and distance measuring instrum ents (DMI). Ensure that DMI have an accuracy of at least 10 foot per m ile and decrease the measured distance when the vehicle backs up.

(2)Provide a target on the lead vehi cle 42 inches above the roadw ay offering a sharp cutoff when it

appears and disappe ars. Ensure that the obs erver's eye in the t railing vehicle is 42 inches above the roadway. 648.3.2 Locating No-Passing Zones

(1)Establish no-passing zones where there is inadequate sight dis tance conforming to the methods

described in 3-2-2 of the departm ent's traffic guidelines manua l. Do not allow the line-of-sight to extend outside the shoulder and ensure that there are no blind spots within the required sight distance.

(2)Establish both ends of no-passing zones to an accuracy of 50 f eet. If the no-passing zone is less than

500 feet long, extend the zone to 500 feet by lengthening at it s beginning in each traffic direction. Conform to the no-passing zone sight distance requirements as follows: NO-PASSING ZONE MINIMUM DISTANCE[1] POSTED SPEED LIMIT SIGHT DISTANCE BETWEEN ZONES 25 - 30 mph 0.10 miles/528 feet 0.10 miles/528 feet 35 - 40 mph 0.13 miles/686 feet 0.10 miles/528 feet 45 - 50 mph 0.16 miles/845 feet 0.13 miles/686 feet 55 mph see[2] 0.15 miles/792 feet [1] If the distance between 2 succe ssive no-passing zones is less than the minimum distance between zones, connect the 2 zones. [2] The no-passing zone sight distanc e is specified in the special provisions.

(3)Establish no-passing barrier lines as the plan details show for features including but not limited to the

following:

1.Major intersections with fu ll right turn lane or bypass lanes.

2.Two-lane to four-lane divided highway transitions.

3.Median islands.

4.Two-lane bridges less than 24 feet wide.

5.Railroad - highway grade crossings.

6.Climbing lanes and passing lanes.

(4)If the contract specifies, also establish no-passing zones on detour routes. Unless the engineer directs

otherwise, use state trunk highway criteria to locate no-passin g zones on county trunk highways and local roads on the detour route. Base the locations on posted d etour speed limits.

(5)Establish no-passing zones at o ther locations the contract spe cifies and at engineer-directed special

locations. Check with the engineer before beginning work to determine if there are special no-passing zones to mark under the contract.

(6)Check the correctness of no-pa ssing zones leading into and out of the project limits. Ensure that the

minimum distance between zones and sight distance are correct. 648.3.3 No-Passing Zone Marks

(1)Spray paint T's and dots on the roadway to mark the beginning and end of all no-passing zones. Make

T's one foot by one foot with at least a 2-inch wide line with a 3 to 4 inch diameter dot on the centerline adjacent to the T stem.

Effective with the December 2018 Letting 460 2019 Standard Spec ifications 648.3.4 No-Passing Zone Log

(1)Upon completing the work, furnish the engineer 4 copies of department form DT2124. Locate features

to the 1/100 of a mile. For east-west roads, log entries from west to east. For north-south roads, log entries from south to north. Log the following: - Date of survey. - Cardinal direction of travel. - Beginning and ending of each no-passing barrier line in both directions. - Sight distance and speed criteria for each zone. - Location of features requiring no-passing barrier lines speci fied in 648.3.2. - Useful geographical references including but not limited to county and regional boundary lines, county trunk highways, and starts and ends of all bridges.

648.4Measurement

(1)The department will measure Locati ng No-Passing Zones by the m ile acceptably completed,

measured as the actual center line length of road surveyed and r eported to the nearest 1/100 of a mile.

648.5Payment

(1)The department will pay for the measured quantity at the contr act unit price under the following bid

item: ITEM NUMBER DESCRIPTION UNIT

648.0100 Locating No-Passing Zones MI

(2)Payment is full compensation for all the work required under t his section.

Effective with the December 2018 Letting 461 2019 Standard Spec ifications Section 649 Temporary Pavement Marking

649.1Description

(1)This section describes providing and removing temporary paveme nt marking.

649.2Materials

(1)Furnish pavement marking materials conforming to 646.2 .

649.3Construction

(1)Construct conforming to the following:

General mar king ............................................... ..................................................................................... 646.3.1.1 Long line ..................................................... ........................................................................................... 646.3.1.2 Removing ma rking .............................................. ................................................................................... 646.3.1.4

(2)Do not groove in temporary marking.

(3)Apply liquid marking and glass beads across the line at or exc eeding the following:

LIQUID MARKING THICKNESS BEAD APPLICATION

(mils)(pounds per gallon)

Paint 12 4 - 5 Epoxy 16 12 - 15

(4)If installing raised pavement mar kers at a new location, use n ew markers. If installing replacement

markers, the contractor may ins tall used markers in like-new co ndition.

(5)For pavements open to all traffi c, apply centerline and no-passing barrier line markings as follows:

- On intermediate layers, includi ng milled surfaces, on the same day the pavement i s placed or milled. - On the upper layer, on the sa me day the pavement is placed un less the contractor a pplies permanent marking on the same day the pavement is placed. - If weather conditions preclude same-day application, delineat e the travel lanes and provide no-passing signing as the engineer directs . Apply centerlines and no-passi ng barrier lines as soon as conditions allow. The engineer may restrict operations until these markings are c ompleted.

(6)If required to apply no passing zone temporary pavement markin g, reference the beginning and end of

existing no-passing barrier lines . Apply temporary no-passing b arrier lines at those existing locations. If the contract contains the Locating No-Passing Zones bid item , relocate permanent no-passing zones as specified in 648.

(7)Protect freshly applied paint marking until dry enough to prevent pickup under traffic. Replace

temporary marking, including ra ised markers, that deteriorates or fails to adhere to the extent that the roadway is not adequately delineated.

(8)Inspect and maintain temporary marking, including raised marke rs, as specified in 643.3.1(5) .

649.4Measurement

(1)The department will measure the EACH bid items under this section as each individual unit acceptably

completed and the LF bid items under this section by the linear foot of line acceptably completed.

649.5Payment

(1)The department will pay for measured quantities at the contrac t unit price under the following bid

items: ITEM NUMBER DESCRIPTION UNIT

649.0100 - 0299 Temporary Marking Line (material/type) (width) LF
