高速公路路面施工方法及工艺流程

摘要：随着交通量和车辆荷载的不断增加，以及自然因素的影响，加上施工技术等问题。我国的高速公路目前采用的主要是热拌热铺沥青混凝土路面，沥青混凝土路面具有表面平整、无接缝、行车舒适、耐磨、振动小、噪音低、施工工期短、养护维修简便、适宜于分期修建等优点，且造价低、施工方便、对周围交通及环境影响小，特别是对修建或改造高速公路路面，具有改善结构性能，提高行车质量，美化路容路貌，提高城市品味的重要作用。热拌热铺沥青混凝土其原理是指矿料与沥青在热态下拌和、热态下铺筑施工成型，特点是矿料、沥青及拌和混合料从拌和到铺筑均须在较高的温度范围内完成。

Abstract: with the traffic and the increase of vehicle load, and natural factors, add construction technology, etc. The highway in our country at present is the major hot mix hot paving asphalt concrete pavement, the asphalt concrete pavement of level off, the surface has no juncture, driving comfort, wear-resisting, little vibration, low noise, construction period is short, the maintenance is simple, suitable for staging built and other advantages, and low cost, convenient construction, transportation and environmental impact on the surrounding small, especially to build or modification of the highway pavement, can improve the structure performance, improve the quality of driving, beautification road let road appearance, improve the taste of the city the important role. Hot mix hot paving asphalt concrete its principle is to point to aggregate and pitch in hot state mixing, hot state are surfacing construction moulding, the characteristic is mine materials, asphalt and mixing mixture surfacing from mixing into shall be at higher temperature range finish.
