Asphalt concrete pavement construction method
The invention relates to the field of concrete, and particularly discloses an asphalt concrete pavement construction method. The construction method comprises the following steps that (1) sundries ona paved road section are cleaned up, and the asphalt concrete is uniformly paved on the road surface according to the road width and the paving thickness; (2) a road roller is used for carrying out initial pressing, re-pressing and final pressing on the road surface, the flatness and the road arch are checked, the aggregate segregation phenomenon is avoided, and rolling wheel marks are eliminated;and 3), the asphalt concrete is maintained after the asphalt concrete is rolled; wherein the asphalt concrete in the step (1) is prepared from the following raw materials in parts by mass: 4-8 partsof cetyl trimethyl ammonium hydroxide; 3-9 parts of triterpenoid saponin; 250-350 parts of asphalt; 1000-1500 parts of a coarse aggregate; and 50-100 parts of a fine aggregate. The rut resistance of the asphalt concrete is improved. According to the asphalt concrete pavement construction method, the asphalt concrete pavement can be compact and flat.
本申请涉及混凝土领域，具体公开了一种沥青混凝土路面施工方法。其施工方法包括以下步骤：步骤1），清理干净所铺设路段的杂物，根据路幅宽度和铺设厚度将沥青混凝土均匀摊铺在路面上；步骤2），用压路机对路面进行初压、复压、终压，检查平整度、路拱、无集料离析现象，消除碾压轮迹；步骤3），沥青混凝土碾压完毕后对其进行养护；所述步骤1）中的沥青混凝土由包括以下质量份数的原料制成：十六烷基三甲基氢氧化铵4‑8份；三萜皂苷3‑9份；沥青250‑350份；粗集料1000‑1500份；细集料50‑100份。本申请的沥青混凝土可以提高沥青混凝土的抗车辙性能。本申请的沥青混凝土路面施工方法可以使得沥青混凝土路面密实平整。
