水泥浆灌孔的沥青碎石路面被称为半柔性路面,半柔性路面有较高的结构承载力和刚度,因此对于改善车辙、推拥等路面病害有显著效果,然而由于目前常对沥青级配碎石进行灌孔,因而存在灌孔困难和灌孔不均匀的问题。采用单级配沥青碎石可形成更大的连通孔隙,使灌孔更加方便、均匀。试验研究表明:水泥浆灌孔单级配沥青碎石有更好的路用性能,更适宜于高等级公路的面层结构。
Asphalt pavement filled with cement slurry is called semi-flexible pavement. Semi-flexible pavement has high structural bearing capacity and stiffness, so it has a significant effect on improving rutting and pushing pavement diseases. However, asphalt pavement With gravel for irrigation, so there is difficulty filling holes and uneven irrigation holes. The use of single-stage with asphalt can form a larger connected pores, making the hole more convenient and uniform. Experimental results show that cement grouting single grade graded asphalt pavement has better road performance and is more suitable for the surface structure of high grade highway.
