concrete overlays meaning in English
混凝土路面加铺
Examples
- 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
反射裂缝扩展是沥青混凝土罩面早期破坏的主要原因。因此在罩面设计中，预防和阻止反射裂缝的扩展是需要考虑的一个重要问题。 - 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
本文采用力学分析与实践经验相结合的方式对沥青混凝土罩面反射裂缝的扩展规律进行了较为系统的研究，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
定期的养护与维修可以延长沥青路面的使用寿命，及时地在沥青路面上加铺罩面，不仅可以增强路面强度，还可改善路面的使用性能，而不必做大量的重建工作，其厚度也小于重建施工的厚度，因此对于已破损的路面，采用沥青混凝土罩面常可以提供最经济的修复形式。
