ASCON FILLER AND ASCON COMPOSITION USING THE SAME

摘要

An asphalt concrete filler is provided to have excellent physical properties, be cheaply produced, and reduce pollutants by using discarded materials. An asphalt concrete composition includes 1-7 wt% of asphalt concrete fillers, 3-8wt% of an asphalt binder, and aggregates. The asphalt concrete fillers consist of waste glass powder generated from a grinding process of waste glass, wherein the waste glass powder has a passing proportion through a 75-micron sieve of 70-100wt% and consists of 50-80wt% of SiO2, 10-50wt% of CaO, and 1-10wt% of Na2O. The aggregate comprises 20-80wt% of coarse aggregate having a maximum diameter of 10 mm or smaller and 10-70wt% of coarse aggregate having a maximum diameter of 13mm or smaller.
