Construction method of semi-flexible asphalt pavement
The invention discloses a construction method of a semi-flexible asphalt pavement, and relates to the technical field of pavement construction, and the construction method comprises the following steps: high-viscosity asphalt is used as an asphalt mixture, and the gradation is broken gradation; the method comprises the following steps: firstly, sequentially paving and rolling an asphalt mixture to obtain a mixture asphalt pavement with the porosity of 25-30%; and then the rapid repairing mortar is poured into pores of the mixture asphalt pavement, and the semi-flexible asphalt pavement is obtained. The rapid repairing mortar is poured into the high-porosity mixture asphalt pavement, so that the thermal stability and mechanical structure stability of asphalt can be improved, the bearing capacity is greatly improved, and the purpose of prolonging the service life of the pavement is achieved. Meanwhile, the obtained semi-flexible asphalt pavement further has the functions of water drainage and noise reduction, and the safety and comfort of driving are improved.
本发明公开一种半柔性沥青路面的施工方法，涉及路面施工技术领域，包括以下步骤：沥青混合料用的是高粘沥青，级配是断级配；先将沥青混合料依次进行摊铺和碾压，得到孔隙率为25％～30％的混合料沥青路面；然后将快速修补砂浆灌注至混合料沥青路面的孔隙内，得到半柔性沥青路面。本发明通过在高孔隙率的混合料沥青路面内灌注快速修补砂浆，可以提高沥青的热稳定性和力学结构稳定性，承载力得到大幅度提高，达到延长路面使用寿命的目的。同时，本发明得到的半柔性沥青路面还具有排水降噪的功能，提高行驶的安全性和舒适性。
