ASPHALT MIXTURE HAVING IMPROVED WATERPROOF PROPERTIES BY INCREASING BINDER CONTENT WHILE MAINTAINING INTERLOCKING

摘要

The present invention relates to an asphalt mixture having improved waterproof properties by increasing binder content while maintaining interlocking, which comprises 89-90 wt% of a mixed aggregate and 8-9 wt% of an asphalt binder and has a porosity ratio of 2-3%, wherein the mixed aggregate has, based on a sieve and weight percentages, 100 wt% of a 20 mm sieve penetration rate, 96.5-100 wt% of a 13 mm sieve penetration rate, 50-55 wt% of a 10 mm sieve penetration rate, 16.5-30 wt% of a 5 mm sieve penetration rate, 12.75-23 wt% of a 2.5 mm sieve penetration rate, 10-18 wt% of a 0.6 mm sieve penetration rate, 8.25-15 wt% of a 0.3 mm sieve penetration rate, 8-15 wt% of a 0.15 mm sieve penetration rate, and 7-13 wt% of a 0.08 mm sieve penetration rate.;COPYRIGHT KIPO 2020
