PENGARUH PENGGUNAAN ZEOLIT ALAM SEBAGAI FILLER PADA CAMPURAN AC-BC DITINJAU DARI NILAI VITM

Abstract

Indonesia has a wealth of natural resources is high, including mineral resources into pavement materials. Utilization of natural resources such as raw materials pavement still has not been developed, especially to overcome the problems related to premature pavement damage. Asphalt Pen. 60/70 and natural zeolite is a natural asset that can be used, but the study linked the two materials are still not widely practiced.Merging the two materials in the testing done with the design of the test specimen using 5 filler content variation, the variation of 1 (100% stone dust: 0% natural zeolite), variation 2 (75% stone dust: 25% natural zeolite), variation 3 (50% stone dust: 50% natural zeolite), variations 4 (25% stone dust: 75% natural zeolite) and variation 5 (0% stone dust: 100% natural zeolite). Then from the value obtained KAO Marshaal testing to obtain VITM value. And the results obtained that the higher bitumen content, then the value of VITM will decrease. This means that the higher the bitumen content, the cavity in the mix will be reduced. This happens because the addition of asphalt to make the air cavity that there is increasingly reduced because filled by asphalt.
