公路工程沥青混凝土路面施工技术
摘要:沥青路面是用沥青材料和混凝土作为结合料辅筑面层的路面的总称,它适用于各种交通量的道路。沥青混凝土面层作为路面结构中最为关键的一层,它的质量直接关系到道路行车的安全性、舒适性、经济性等。因此最好公路工程沥青混凝土路面施工技术的研究具有重要意义。本文首先对沥青混凝土路面施工的准备工作做了说明,然后从拌合、运输、摊铺、碾压和施工缝处理五大方面详细探讨了沥青混凝土路面施工技术的要点,最后对其质量控制要点做了简要说明。

Abstract: asphalt pavement with asphalt material and concrete as binder and auxiliary building the floorboard of the surface of the pavement, it is suitable for all kinds of traffic road. Asphalt concrete pavement as the most critical in the pavement structure layer and its quality is directly related to road traffic safety, comfort, economy and so on. So it's best to highway construction of asphalt concrete pavement construction technology research is of great significance. This article first to the asphalt concrete pavement construction preparation work done, and then from the mixing, transportation, paving, compaction and construction joint treatment five aspects discusses the main points of the asphalt concrete pavement construction technology in detail, and finally made brief explanation for its quality control points.
Key words: asphalt; Concrete; Mixing; Transport; RCC

施工准备工作
(一)原材料检验
1、沥青的选用
通常沥青混凝土路面采用的沥青有煤沥青、石油沥青、液体石油沥青、改性沥青等。应该根据路面的结构、施工条件、道路等级、施工方法等选用恰当的沥青标号。煤沥青一般只用于透层施工,不适合做面层材料用。当选用乳化沥青时,应该根据石料的酸碱性分别采用阳离子乳化沥青与阴离子乳化沥青。
