旧混凝土路面补强时常在原有路面上加铺一层沥青罩面，当混凝土位移产生的拉应力超过沥青罩面层的抗拉强度时，罩面层就会开裂，这种裂缝即称为反射裂缝。

因此反射裂缝的研究一直是这种组合结构研究的重点和难点。
So it is important to research the reflection crack to this composite structure, and it is difficult too.
反射裂缝导致面层开裂、剥落，路面水沿裂缝下渗，使路面发生损坏。
Reflective crack caused surface cracking, spalling, surface water infiltrating along the seam, so that the road was damaged.
开展旧混凝土路面上加铺沥青面层防治反射裂缝的研究，是很有必要的。
Launch old concrete road surface is it spread pitch layer is it reflect research of crack to prevent and cure to add, it is very necessary.
