通过加铺层试验路观测与理论计算分析表明，大粒径沥青碎石裂缝缓解层可有效地防止或减缓水泥混凝土路面沥青加铺层的反射裂缝。

The investigations of testing highway and results of theoretic calculation indicate that the extra large-size asphalt macadam layer can prevents asphalt overlay from cracking effectively.

在旧水泥混凝土路面与沥青加铺层之间设置大粒径的沥青稳定碎石中间夹层，为这一问题的解决提供了新的方向。

So to establish a large-size asphalt treated base between asphalt overlay and old concrete pavement provides a new method to solve the problem mentioned above.
