Abstract

HRS – Base (Hot Rolled Sheet – Base) is one of the surface layers that is in direct contact with traffic vehicles, so the quality of the asphalt concrete mix is largely determined by the quality of its constituent aggregates. The strength of the aggregate on the abrasion value is very influential on the stability. The purpose of this study was to determine the effect of the abrasive value of coarse aggregate from the Bipolo and Takari quarry on the characteristics of the asphalt concrete mixture. The variation of the abrasion value used is 20.74% and 22.66%. Marshall parameters meet the specifications of Bina Marga 2018 Revision 3, Laboratory research results show that in Quarry Bipolo: Stability value = 1045.1 Kg, Flow value = 3.68 mm MQ value = 286.6 Kg/mm, VIM value = 5 ,21 %, VMA value = 18.40 %, VFB value = 74.00 %, these results meet the specifications with a minimum stability value of 600 kg, a minimum flow value of 3 mm, a minimum MQ value of 250 kg/mm, a minimum VIM value of 4 % and Maximum 6 %, Minimum VMA Value 17%, Minimum VFB Value 68%. As for Quarry Takari: Stability value = 1066.7 Kg, Flow value = 3.69 mm MQ value = 287.5 Kg/mm, VIM value = 4.97%, VMA value = 18.19%, VFB value = 72 ,39%, these results meet the specifications with a Minimum Stability Value of 600 Kg, Minimum Flow Value of 3 mm, Minimum MQ Value of 250 Kg/mm, Minimum VIM Value of 4 % and Maximum 6%, Minimum VMA Value of 17%, Minimum VFB Value of 68% .
