- However , the pavement is easily spoiled by reflective cracking from semi - rigidity base because semi - rigidity base is sensitivity to low temperature and little humidity , so through adverse circumstance and reduplicate vehicle load . the base can have easily rupture by much dryness and low temperature . then these interior fractures will extend to exterior asphalt
这是因为半刚性基层材料对温度和湿度反应敏感。在环境和重复交通荷载作用下，基层容易产生干缩和低温缩裂裂，半刚性基层这些裂缝会扩展到面层，形成反射裂缝。 - On systematic analysis of engineering property of the aeolian sand , we choose cement stabilized aeolian sand , cement stabilized mixture of aeolian sand and soil , lime - fly ash stabilized aeolian sand , lime stabilized mixture of aeolian sand and soil and lime - cement stabilized mixture of aeolian sand and soil as object of research . on the base of the determination and analysis of temperature contraction property , aridity resistance property and strength of the stabilized aeolian sand mixture , this paper mainly analyses influential factors and inherent law of property about the stabilized aeolian sand mixture , and provides scientific foundation for the using of aeolian sand as paving material
本文在系统分析风积沙工程特性的前提下，以水泥稳定风积沙、水泥稳定混合沙土、石灰稳定混合沙土、石灰粉煤灰稳定风积沙和水泥石灰稳定混合沙土作为底基层材料研究对象，在对其温缩、干缩以及强度和模量等性能指标的测试、分析的基础上，研究分析了这些稳定风积沙混合料各性能的影响因素和内在规律，为风积沙用作沙漠地区公路路面材料提供了科学依据。 - Pavement cold - in place recycling is a new technique of form pavement structure , it include three steps : the fist step is the processing of old asphalt pavement material including asphalt pavement and parts of road base material , then add some new bone - material or thin material to these material according to the characteristic of cold recycling structure , at the same time add some water and in addition matter according the quantity of material , at last deal with these material in environment condition to form an new structure
路面冷再生技术就是将旧沥青路面材料(包括沥青面层和部分基层材料) ，经过锨刨加工进行重复利用，并根据再生后结构层的结构特征，适当加入部分新骨料或细集料，按比例加入一定量的外加剂和适量的水，在自然环境下连续完成材料的一系列加工工艺，重新形成结构层的一种工艺方法。
