当你沿着沥青马路向前跑的是很，你要小心很多东西，玻璃，碎石，不平整的人行道，路面的裂缝等等。
The asphalt pavement on cement-stabilized crushed stones base produces cracks easily so that the structure of pavement is destroyed too easily, specially under heavy vehicles.
水泥稳定碎石基层沥青路面容易产生裂缝，特别在重载交通条件下，路面结构更容易过早破坏。
It was necessary and feasible to study the design to prevent reflecting cracks on the asphalt overlaid on the old cement concrete pavement.
因此继续开展旧水泥混凝土路面上加铺沥青面层防治反射裂缝设计方法的研究，是必要而且是可行的。
