| 摘 要： | 为了提高路面结构中级配碎石基层的回弹模量,通过材料设计、路面结构组合设计和施工工艺设计,对级配碎石基层的使用性能进行了研究。材料设计的目的是确定出使用性能较好的级配,这是提高其使用性能的内在因素;结构组合设计的目的是以刚性较强的半刚性材料作为级配碎石的底基层,充分发挥级配碎石的强度非线性性能;碾压程序和机具组合设计的目的是形成稳定、均匀的结构层,这是提高使用性能的保证。综合考虑以上因素的试验路模量反算结果表明:级配碎石的强度有大幅度提高。

| Abstract: | In order to enhance modulus,the design of materials,structural combination and construction technology of the graded broken stone base were studied.The aim of materials design is high quality graded broken stone mixture can be gotten and it is inherence factor to enhance its using performance.In structural combination,non-linearity performance of graded broken stone base can be elaborated fully if semi-rigid material is its sub-base;scientific compacting procedure and right selection of roller machine are the key to form stable layer.Results indicate that the modulus can be improved largely by using above three methods in the design and construction of graded broken stone base. |
