Asphalt paving method for road construction
The invention provides an asphalt paving method for road construction. The asphalt paving method comprises the following steps: preparing and mixing an asphalt mixture; wherein the asphalt mixture comprises SBS modified asphalt, coarse aggregate, fine aggregate, mineral powder and basalt fiber; wherein the mass parts of the SBS modified asphalt, the coarse aggregate, the fine aggregate, the mineral powder and the basalt fiber are 32-42 parts, 10-12 parts, 15-18 parts, 28-32 parts and 0.2-1 part respectively; paving an asphalt mixture; rolling construction, including initial pressing, secondarypressing and final pressing; and performing joint construction. According to the asphalt pavement method for road construction, the pavement construction quality of the asphalt concrete road can be guaranteed, the high-temperature stability and the low-temperature crack resistance of the asphalt road can be enhanced, and the service life of the asphalt road is prolonged.
本发明提供了一种道路施工用沥青铺设方法，包括下列步骤：准备沥青混合料并拌制；其中，沥青混合料包括SBS改性沥青、粗集料、细集料、矿粉和玄武岩纤维；所述SBS改性沥青、粗集料、细集料、矿粉和玄武岩纤维的质量份数分别为32～42份，10～12份，15～18份，28～32份，0.2～1份；沥青混合料摊铺；碾压施工，包括初压、次压和终压；接缝施工。本发明的道路施工用沥青铺设方法既能保障沥青混凝土道路铺设施工质量，又能增强沥青道路的高温稳定性和低温抗裂性能，延长沥青道路的使用寿命。
