15、 in the mix. No payment will be made for defective areas until corrected.1.1.1.2 Correctional Factor for Aggregates UsedQuantities of paving mixtures called for in bid schedule are based on aggregates having a specific gravity of 2.65 as determined according to apparent specific gravity paragraphs i
16、n ASTM C 127 and ASTM C 128. Make correction in the tonnage of bituminous base course mixtures to compensate for the difference in the tonnage of mixtures used in the project, when specific gravities of aggregates used are more than 2.70 and less than 2.60. The tonnage paid for will be the number of
17、 tons used, proportionately corrected for specific gravities using 2.65 as the base correctional factor.1.1.1.3 Bituminous MaterialMeasure bituminous material to be paid for in the number of liters gallons of the material used in the accepted work, corrected to liters gallons at 15 degrees C 60 degr

32、ities of bituminous mixtures required for the project within the completion time of the contract. Provide hauling equipment, paving machines, rollers, miscellaneous equipment, and tools in sufficient numbers and capacity and in proper working condition to place the bituminous paving mixtures at a ra
33、te equal to the plant output. A sufficient number of adequately trained personnel shall be available during paving operations to produce a pavement meeting the requirements in this specification.1.3.2 Mixing Plants*NOTE: The type and capacity of the plant, the number and size of trucks, paving machi
34、nes, and other equipment should be determined from the tons of paving mixtures required, haul distances, number of working days permitted by the contract, and other pertinent factors.*SECTION 32 11 26 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS
