级配碎石基层级配设计及应用研究
|
摘要
半刚性基层沥青路面由于良好的强度及抗疲劳性能,因而广泛用于国内外重交通道路路面结构,大量的使用情况调查表明,裂缝是半刚性沥青路面的主要病害,造成高速公路沥青路面早期病害发生的重要原因。随着级配碎石基层具有良好的排水及消除反射裂缝功能和优良的经济性被人们在认识后,含级配碎石柔性基层柔性路面结构也必将成为我国未来高等级公路路面结构多样化发展的重要结构之一,基于上述背景,论文就级配碎石级配设计及应用进行了研究。
本论文首先对级配设计设计方法做了研究,主要从泰波公式不同的幂指数n值和均匀设计法对应级配的粗集料骨架空隙率两方面对级配碎石基层的粗集料骨架组成规律进行深入研究,提出了基于幂指数n值和均匀设计法而形成对应级配,通过对级配碎石基层的粗集料骨架的组成规律进行深入研究,并通过CBR值和空隙率得到最佳级配。由于用CBR值反映了级配碎石力学强度且和回弹模量有一定的关系;孔隙率在一定程度上也反映了级配碎石强度、塑性总变形、渗透性能这三项指标,且CBR值和孔隙率这两项指标评价级配碎石性能简单易行,因而可以将其作为级配碎石设计指标。接着对级配碎石回弹模量、CBR值、塑性总变形的影响因素进行分析,并进行回弹模量试验、CBR试验,对级配碎石基层的路用性能做了研究,并且对级配碎石基层的防裂机理做了探讨。
然后,对高速公路级配碎石基层的施工技术进行了系统研究,提出了适合湖南省高速公路的级配碎石基层的施工质量控制指标,在实际工程应用中效果良好。
最后,在上述工作的基础上,分析了本文研究的不足之处,为下一步工作的开展提出了一些观点。
Because of fine strength and fatigue resistence, semi-rigid base asphalt pavements are widely used in pavement structures of heavy-traffic road in our country and overseas. lots of cases show crack is the main disease of semi-rigid base asphalt pavement and the cause of early occurrence of diseases of asphalt pavements of highways .After the unbound stone aggregates is provided weth excellent drainage, dispelling reflection cracking function and fine economics understand, flexible pavement structure weth the unbound stone aggregates base will become an important structure of high-graded road pavement which is diversification developing in the future.
First of all, This thesis according to the n value and the even design method calculate first to goes together with in response to the primary election class, through the unbound stone aggregates base level of thick gather to anticipate constituting of framework of the regulation carry on a thorough research, and through CBR value and crevice rate select the best grading. We analyze influence factor of the unbound stone aggregates modules, the CBR value, the plastic deformation, modules of resilience. Carrying on the experiment with modules of resilience, the CBR experiment and provides the reasonable design variance for the material design and the structural design. We analyze the anti-crack mechine of unbound stone aggregates base.
Secondly, we systematically researched the construction technique of the superhighway’s unbound stone aggregates base and put forward suitable the construction quality control index sign of superhighway’s unbound stone aggregates base in Hunan, the effect was good in the actual engineering application. Finally, according to the rule of the whole tests, it gives some advice on how to carry on the subsequently research.
