Reflection cracking is the main cause for early deterioration of bituminous concrete overlays, and therefore its prevention is an important consideration in the design of overlays
反射裂縫擴展是瀝青混凝土罩面早期破壞的主要原因。因此在罩面設計中，預防和阻止反射裂縫的擴展是需要考慮的一個重要問題。 -
This thesis utilized a mechanic - empirical approach the for prediction of reflection cracking life of asphalt concrete overlays. a mechanic - empirical approach was utilized in developing the present design procedure. the achievements we obtained was listed as the following : 1
本文採用力學分析與實踐經驗相結合的方式對瀝青混凝土罩面反射裂縫的擴展規律進行了較為系統的研究，取得的主要成果有： 1 -
Periodic maintenance and rehabilitation can prolong the road ' s service life. an asphaltic overlay is applied to the old pavement surface in good time, which not only enhances the strength of the pavement, but also improves the using performance of the old pavement instead of doing lots of rebuilding works. therefore, the thickness of asphalt concrete overlays is less than the thickness of the reconstructed pavement
定期的養護與維修可以延長瀝青路面的使用壽命，及時地在瀝青路面上加鋪罩面，不僅可以增強路面強度，還可改善路面的使用性能，而不必做大量的重建工作，其厚度也小於重建施工的厚度，因此對于已破損的路面，採用瀝青混凝土罩面常可以提供最經濟的修復形式。 -
