摘要: The presence of stone-on-stone contact and a relatively low percentage fine aggregate are two characteristics stone-matrix asphalt (SMA). Although it is known that the stone skeleton in SMA primarily responsible for its high rutting resistance, method to quantitatively determine has not been used United States. A simple laboratory was developed with conventional hot-mix parameters such as voids mineral aggregate, coarse dry-rodded weight aggregate. Tests were conducted evaluate effect percent passing 4.75-mm sieve on susceptibility mix stability change void content. It observed mixes less sensitive air contents. Mixtures (No. 4) (30 or less) tended have contact.
