所谓碾压式沥青混凝土,是英国正在推行的代表性的工法,是积累了七十年以上的研究和经验的耐磨性、抗滑性及耐久性方面出色的路面。在日本,以往作为沥青混凝土路面的面层所用的混合料,一直是采用连续级配的沥青混凝土,对于荷载的变形作用,混合料的稳定性是依靠骨料的内部摩擦。最近,因为路面的抗滑作为一个大的问题被提出来了,所以既要追求路面面层的性状是理想的状态,又要考虑是路面排水良好的粗面,还要考虑用难以滑动的路面骨料。但是,一般将 The so-called roller compacted asphalt concrete is a representative workmanship that is being carried out in the UK. It is an excellent road surface with more than 70 years of research and experience in terms of abrasion resistance, skid resistance and durability. In Japan, the asphalt mixture that used to be the surface layer of asphalt concrete pavement in the past has been asphalt concrete with continuous grading. For the deformation of load, the stability of mixture depends on the internal friction of aggregate. Recently, since the anti-skidding of the pavement has been proposed as a big problem, it is necessary to pursue the pavement topography in an ideal condition and to consider the surface roughness of the road surface as well as to consider the pavement aggregate. But generally
