沥青混凝土具有相当高的强度,良好的防水性能以及产生弹性和塑性变形的能力。沥青砼路面平坦而富有弹性,从而相对减小交通噪音,保证车胎良好的路面附着力。尽管沥青混凝土有上述优点,但它在铺设5年左右,就会失去那些优良特性,产生路面裂缝,继而发生路面破坏。造成这一现状的原
Asphalt concrete has a very high strength, good water resistance and the ability to produce elastic and plastic deformation. Asphalt concrete pavement is flat and flexible, which reduces traffic noise and ensures good road surface adhesion. Although asphalt concrete has the above-mentioned advantages, when it is laid for about five years, it will lose those excellent characteristics, causing cracks in the road surface and then causing road damage. The original cause of this situation
