402.01 DESCRIPTION. Furnish and construct surfacing for
maintenance of traffic on driveways, pipe crossings, short-term traffic on raw embankment, slope corrections, or other disturbed roadway sections as directed and in accordance with the following requirements.
402.02 MATERIALS. Furnish any of the following types of materials
complying with the following sections and subsections and in accordance with the following requirements. Other materials must be approved in advance by the engineer. Stone 1003.01 & 1003.05.1 Recycled Portland Cement Concrete 1003.01.3.1 & 1003.05.1 Reclaimed Asphalt Pavement 1003.01.3.2 & 1003.05.3 Asphalt Concrete 1 Section 502 Flowable Fill 2 Section 710 1 All asphalt mixes in Section 502 will be allowed for surfacing materials. 2 Flowable fill surface shall meet the excavatable requirements of Table 710-1.
402.03 EQUIPMENT. Furnish and maintain equipment necessary to
produce a finished product meeting the requirements of these specifications. Obtain approval of equipment prior to use.
402.04 CONSTRUCTION REQUIREMENTS. Satisfactorily place,
shape, compact, and maintain areas requiring traffic maintenance surfacing. When directed, reuse the aggregate material at adjacent locations when the material can be reasonably shifted by blading. When directed, material shall be loaded, hauled, and reused. Unless otherwise directed by the project engineer, remove and dispose of traffic maintenance surfacing when no longer necessary. Dispose in accordance with Section 202.
402.04.1 Mainline Surfacing: For mainline roadway, use traffic
maintenance surfaces in accordance with Table 402-1 at the posted speed limit during construction. Aggregate surface is allowed only when all aggregate table criteria are met. Hard surface is required when any hard surface table criteria is met. Hard surface will be either asphalt concrete or excavatable flowable fill with a minimum thickness of 6 inches. Surfacing shall be uniform and smooth. Surfacing shall meet a 1/2 inch longitudinal tolerance with a 10 - foot static straight edge and shall properly drain. Asphalt concrete surfaces shall have a minimum of 89 percent of maximum dry density. Should a contractor’s operation or sequence of construction extend the time an aggregate surface remains in place under traffic beyond four weeks, hard surfacing will be at no additional pay. Should a contractor’s operation or sequence of construction necessitate the use of aggregate in areas requiring hard surface, place the hard surface within 48 hours. Placement of aggregate surfacing in this case will be at no direct pay.
402.04.2 Non-Mainline Surfacing: Use either aggregate or hard
surfacing for turnouts, drives, crossovers and other non-mainline segments of roadway. If using hard surfacing, it shall meet the requirements of
402.04 1.
Table 402-1 Mainline Traffic Maintenance Criteria Surface Type ADT Posted Speed, mph Time Surfacing to Remain In Place Under Traffic Aggregate ≤5000 ≤45 ≤4 weeks 1 Hard Surface >5000 >45 >4 weeks 1 Time may be extended with approval of the Project Engineer.
402.05 MEASUREMENT. Aggregate used for traffic maintenance
surfacing will be measured at the point of delivery by the cubic yard in approved hauling vehicles in accordance with 109.01. No adjustment factor will be used. Hard surfacing will be measured by the square yard at the roadway location.
402.06 PAYMENT. Payment for traffic maintenance surfacing,
maintained and subsequently removed, when required, will be made at the contract unit prices per cubic yard or per square yard. Aggregate materials reused by blading to adjacent locations will be at no expense to the Department . Aggregate material reloaded, hauled, and re- used will be paid at 50 percent of the contract unit price. Payment will be made under: Item No. Pay Item Pay Unit 402-01 Mainline Traffic Maintenance Surfacing (Aggregate) (Vehicular Measurement) Cubic Yard 402-02 Mainline Traffic Maintenance Surfacing (Hard) Square Yard 402-03 Non-Mainline Traffic Maintenance Surfacing (Aggregate) (Vehicular Measurement) Cubic Yard PART V—ASPHALT PAVEMENTS Section No. Page No. Section 501 Thin Asphalt Concrete Applications ................................................................ 161 Section 502 Asphalt Concrete Mixtures .............................................................................. 174 Section 503 Asphalt Concrete Equipment and Processes .................................................. 277 Section 504 Asphalt Tack Coat .......................................................................................... 291 Section 505 Asphalt Prime Coat ......................................................................................... 294 Section 506 Asphalt Curing Membrane .............................................................................. 296 Section 507 Asphalt Surface Treatment ............................................................................. 298 Section 508 Vacant ............................................................................................................. 308 Section 509 Milling Asphalt Pavement ................................................................................ 309 Section 510 Asphalt Concrete Pavement Patching, Widening and Joint Repair ................ 312
