双夹层对旧水泥路面沥青加铺层结构的影响

Influence of Two-layer Sandwich on Asphalt Overlay Structure on Old Cement Concrete Pavement

为确定双夹层对沥青加铺层结构应力的影响,采用有限元计算模型,全面分析不同夹层结构对沥青加铺层荷载应力、温度应力的影响规律,并进一步研究土工织物模量对双夹层结构荷载应力和温度应力的影响规律。结果表明:双夹层可减小沥青加铺层结构的荷载应力和温度应力。

To determine the influence of two layer sandwich on structural stress of asphalt overlay, the law of the influence of different sandwich structures, as well as the geotextile modulus on load stress and temperature stress of asphalt overlay was comprehensively analyzed by finite element method. The result shows that： two layer sandwich can reduce the load stress and temperature stress of asphalt overlay structure.
