212 taken to reestablish the temperature of the mix within the plant tolerance. When measured at the project site, the temperature of the mix shall be within the tolerance established by the JMF. The first truck load of material which demonstrates temperatures outside of that range or any trucks in transit at that time shall be accepted provided temperatures are within the master temperature range. Any truckload of material which exceeds the m aster temperature range may be rejected by the Engineer. However, the plant shall immediately be notified that no additional loads of material are to be dispatched until necessary action is taken to reestablish temperature within JMF specification limits. When the surface temperature falls to within 10°F of the weather restrictions of Table 410.8, the mix temperature may be increased up to a maximum of 338°F unless otherwise specified by the asphalt supplier. The temperature of each truckload of material shall be monitored for compliance. Any truckload of material which exceeds this maximum temperature may be rejected by the Engineer. Mixes produced with asphalts that contain modifiers for high or low temperature performance enhancement shall meet the te mperature requirements recommended by the asphalt supplier, as determined using the mid-point of the mixing temperature range shown on the asphalt temperature -viscosity charts and allowing for ± 25°F.
410.10.2 Safety Edge: When the total specified lift thickness of pavement is 1.5 inches
or greater, asphalt safety edge shall be constructed on the outside pavement edge. The device utilized shall be a model listed on Division Approved Product Listing. The resulting finished surface of the safety edge shall be sufficiently consolidated so as to show no segregation or raveling of the aggregate and shall have the same surface profile and texture of the compacted mat surface. Safety edge is not to be used through intersections, against curb or barrier, or when directed by the Engineer. The paving operation shall allow for automatic and/or manual transitions at cross roads, driveways, and intersections. The Engineer may allow short sections of handwork for transitions at driveways, inters ections, interchanges, and bridges.
410.11 Protection of Pavement and Traffic Control :
The Contractor shall be responsible for the protection of asphalt surfaces from damage by their equipment and personnel. When the construction of asphalt surfaces is undertaken on projects under public traffic and the road surface is sixteen ( 16) feet wide or greater and the ADT is 400 or greater, the Contractor shall place no passing signs, Interim pavement markings, and Temporary pavement markings to delineate the edge line, centerline, and/or lane line of the roadway as required herein and in the project plans. The provision of Section 336: Maintaining Traffic shall apply. Interim markings are described as markings applied to freshly resurfaced roadways between lifts and after placement of the final lift prior to opening the portion of the roadway being resurfaced to traffic. These markings are intended to provide the minimum amount of delineation required for safe navigation of the roadway and are to be succeeded by Temporary markings within a three (3) to fourteen (14) day period, based on the type of roadway and ADT, as specified herein. Interim and Temporary markings shall conform to the requirements of Section 663: Pavement Markings.
410.12 Method of Measurement :
Asphalt will be measured by the Square Yard (SY). The quantity will be determined by the Plan Quantity as provided for in the proposal unless otherwise directed by the Engineer. 213 Any patching or leveling mixture placed on a subbase or base co urse constructed in the same Contract with the asphalt items shall be at the expense of the Contractor. No additional compensation will be allowed for the material or any work incidental to its placement unless otherwise approved by the Engineer. No additi onal measurement is necessary nor will addition compensation be allowed for the placement of Safety Edge.
410.13 Basis of Payment :
The quantities determine as provided above, will be paid for at the contract unit price for the items listed below, which prices and payment shall be full compensatio n for furnishing all the materials and doing all the work herein prescribed in a workmanlike and acceptable manner, including all labor, tools, equipment, field laboratory, supplies, tack coat, and incidentals necessary to complete the work and provide the performance criteria specified. There will be no additional compensation for Interim Pavement Markings .
410.13.1 When a Lot of asphalt material is found not in compliance with the tolerance
requirements for asphalt content and gradation as shown in MP 401.02.31, it shall be subject to a price adjustment in accordance with the criteria for Determination of Percent Within Limits established in MP 401.13.50 and pay factors in Table 410.13.3.1.
410.13.2 : Blank
410.13.3 For Interstates and divided NHS Highways, the unit price for each Lot of asphalt
pavement Mat shall be adjusted as follows in Table 410.13.3.1 in accordance with MP 401.13.50. For two -lane and non -divided NHS Routes, the pay factor for asphalt content and percent passing the 75 μm (No. 200) sieve shall be determined by Table 410.13.3.1. However, the mat density pay factor shall be determined by Table 410.13.7.2. TABLE 410.13.3.1 Percentage of Material Within Specification Limits (PWL) Lot Pay Factor (Percent of Contract Unit Price) 90-100 100 75-89 [(0.5)PWL]+55 55-74 Note 1 [(1.4)PWL] -12 Note 1 Material with a PWL less than 55 is considered defective and will be considered for removal and replacement of the lot. If only one lot characteristic has a percent within limits less than 55, the Engineer, may allow the Contractor to leave the defective lot in place. The decision to remove and replace the subject lot shall include evaluation of all lot characteristics for pay and surface characteristics as per guidelines set forth in MP
401.07.25 If the material is left in place, the Department will pay for the defective lot at
a value not to exceed 50% of the contract unit price of asphalt per square yard. (i.e., Contract unit pr ice = $10 sy → $5 sy max)
