| 摘 要： | 目前的公路大部分都通过采用改性沥青来提高沥青道路的路用性能．但在实际中．往往会出现实验与实际不符的情况，因此针对这一问题进行具体的配合比设计及其施工装备和工艺的改进，是提高沥青混凝土路面质量的根本保证．尤以矿料级配、沥青及骨料的加热温度和压实成型最为关键．

| Abstract: | Most of current highway use modified asphalt to advance the service performance, but in practice, experiments often appear inconsistent with the actual situation. So, aiming at the specific problem, the material mix proportion design and improvement of construction equipment and construction technique are the fundamental guarantee of advancing the quality of asphalt concrete, especially, mineral aggregate gradation, heating temperature of asphalt and aggregate, as well as compaction and formation are the most crucial. |
