4−26 402.03.4 Time Limitation. Friction course shall only be placed between the period of June 1st to August 31st. 402.04 METHOD OF MEASUREMENT.
402.04.1 Dense Friction Course. "Dense Friction Course" will be measured by the number of
tons actually placed in accordance with the Plans and/or as directed by the Engineer. 402.04.2 Ramp Friction Course. "Ramp Friction Course" will be measured by the number of tons actually placed in accordance with the Plans and/or as directed by the Engineer. 402.04.3 Ten Percent Limitation. Pavement thickness will be considered acceptable when placed within the tolerances specified. The total tonnage delivered and placed shall not exceed the tonnage calculated from the approved areas measured fr om the final surface course width, by the project length, and the pavement thickness in the Contract, by more than 10 percent. A thicker pavement may be acceptable; how ever, no payment shall be made for any quantity of asphalt concrete delivered which exceeds 110 percent of the final measured length, times measured width, times specified thickness, times unit weight. 402.05 BASIS OF PAYMENT. The accepted quantities of "Dense Friction Course" and "Ramp Friction Course" will be paid for at their respective contract unit prices per ton as listed in the Proposal. The prices so-stated constitute full and complete compensation for all labor, materials and equipment and all incidentals required to finish the work, complete and accepted by the Engineer.
403.01 DESCRIPTION . This work consists of furnishing, delivering, and placing a liquid asphalt

403.02 MATERIALS. The asphalt emulsion shall be RS-1.
403.03 Construction Methods.
403.03.1 Equipment. Application of the asphalt emulsion tack coat shall be by means of a pressure
distributor capable of producing a uniform continuous fine spray, through multiple nozzles, resulting in a uniform continuous coat of asphalt emulsion over the entire section to be treated. Any puddles of tack coat shall be squeegeed or broomed out or corrected by whatever means chosen by the Contractor which will achieve the required surface treatment. Any areas not receiving the specified coverage of tack coat shall be corrected and brought into compliance.
