本文为寻求沥青面层单机全幅摊铺的铺筑效果,将统计的沥青上面层压实度按检测点距中情况分为“距中0~3.5m”、“距中3.5~7.0m”及“距中7.0到边缘”3个区段,结果表明:“距中3.5~7.0m”区段压实度最好,“距中0~3.5m”区段与“距中7.0到边缘”区段压实度几乎一样,但“距中0~3.5m”区段稍好些;且全幅一次摊铺引起的两边离析,经压实后形成不同的骨架结构、不同类形的孔隙率,导致在压实度相同的情况下,渗水系数不同、甚至相差很大。
In order to seek the paving effect of single-face full-width asphalt pavement, the compaction degree of the upper asphalt pavement is divided into “distance 0 ~ 3.5m ” and distance 3.5 ~ 7.0 m “and” from “7.0 to the edge of the ” 3 sections, the results showed that: “from the 3.5 ~ 7.0m ” section of the compaction degree is best, “from 0 ~ 3.5m ” area The section is almost the same as the section from “7.0” to the “edge”, but the section “slightly apart from 0 ~ 3.5m” is slightly better; and the two sides caused by paving in one section are separated and compacted to form Different skeleton structure, different types of porosity, resulting in the same degree of compaction, water seepage coefficient is different, even very different.
