- Adopt stabilized material mixer with full - electronic automatic measuring system to centralizedly mix the cement stabilized subbase materials , and adopt our company ' s own paver to pave on the construction site , use the road roller to roll into the shape
水泥稳定基层材料采用有全电子自动计量系统的稳定料拌和机进行集中拌制，施工现场采用我公司自有的摊铺机摊铺，压路机碾压成型。 - This paper presents checking method of using predigested formula to calculate construction deflection checking value of base according to the strength of the semi - rigid base materials increases with their age ; and advances pavement base construction deflection value checking criterion , provides checking basis for controlling pavement construction
本文在考虑半刚性基层材料强度随龄期增长规律的基础上，提出采用简化公式计算路面基层顶面施工弯沉值的检验方法；并结合宁夏公路路面典型结构，提出路面基层施工弯沉值检验标准，为控制路面施工质量提供了检测依据。 - Because the best grade limits does not vary with material property , firstly , we can confine material grade to the best grade limits when doing subbase mixture design , secondly , after systematic temperature contraction test , aridity contraction test and compressive strength correction test , we can determine the best cement percentage which has the best crack resistance property
因为最佳级配范围是与粒料的粒径大小有关的，所以在基层材料配合比设计时可首先将材料级配限制在最佳级配范围以内，然后通过系统的温缩、干缩性能试验以及抗压强度校核试验，最终确定抗裂性较好的合理水泥剂量。 - Based on above research results , mechanism of the mixture features is studied by some methods , such as chemical analysis , electron microscope and x - raying and so on to explain the characteristic principle . research conclusion confirms it is the high content of useful fly - ash composition and the high structure polymeric degree that lime fly - ash mixture not only can present possibility of delayed base compaction and strength regeneration compared with other base materials but also can take continuous construction process to compact base course and pavement
认为正是粉煤灰具有的高比例有效成分含量，以及结构上呈现的高度聚合的稳定性，使粉煤灰石灰混合料与其它常见的半刚性基层材料相比，不但能表现出显著的碾压成型的可延迟性、结构强度的可恢复性，而且还具有在一定条件下能够采用基层和沥青面层连续施工的独特性质。 - Through the experimental research , we think : the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam , however , if use elasticized capacity to solve blending technological problem . adjust the breed of fiber silk , extend its diameter , its paving capacity is still worth exploring , asphalt - rubber macadam structure lager have good deformed - become capacity and crazed - resistance capacity , small gap rate . good water - resistance capacity , good hot - stability and simple construction technology . therefore . pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue . and is the good structural measure of preventing half - rigidity grass - roots unit shrink - rift reflecting . pave a thin layer of pitch rubber spall between asphalt - type pavement layer and half - rigidity basic level , although the cost of building is higher than paving togongbu in the middle , the construction technology , crazing - resistance and water - resistance are better than togongbu , not only could reduce greatly the reflex of half - rigidity grass - roots unit material , long then the use lifespan of pavement , but also it is possible to reduce suitably the thickness of asphalt mixture layer , though the cast of building in the early days becomes more , in the long - term opinion , it have fully important technological and economical significance
通过试验研究认为：玻璃纤维沥青碎石的技术性能不如沥青碎石好，但路用弹性性能较好，如能解决拌和工艺问题，调整纤维丝的品种，增大其直径，其路用性能仍值得探讨，沥青橡胶碎石结构层具有变形性能和抗裂性能良好，空隙率小，防水性能好，热稳定性较好，施工工艺简单的特点，因此，沥青橡胶碎石是二级及二级以下公路因疲劳而开裂的沥青路面的良好罩面材料，也是防止半刚性基层收缩裂缝反射的良好结构措施，在沥青类路面面层和半刚性基层之间夹铺沥青橡胶碎石薄层，虽然造价比夹铺土工布高，但其施工工艺，抗裂性能和防水性能均优于土工布，不仅可以大大减少半刚性基层材料的反射裂缝，延长路面使用寿命，而且可能适当减薄沥青混合料面层的厚度，虽然初期造价有所增加，从长远来看，具有十分重要的技术和经济意义。
