摘要
In order to study the effect of the raw material's properties to the HMA's pavement performance, the asphalt, coarse aggregate and fine aggregate are studied. The test results show that: the modified asphalt content is more than the base asphalt with the same aggregate and gradation. The former's pavement performance is obviously better than the latter's. The granite mixture's asphalt content is less than the gabbro mixture. Their high and low temperature performances are in the same level, but the former's water stability is worse.
