摘要
本文针对青海海西地区气候干燥、交通量小、沙砾资源丰富的特点,就级配碎砾石基层沥青路面使用效果展开了较为系统的研究。
在对青海省格茫二级公路、绿黄二级公路、当冷花三级公路路段调查检测的基础上,采用我国路面评价体系及COST354沥青路面使用性能评价体系,对比评价了青海海西地区级配碎砾石基层沥青路面和水泥稳定砂砾基层沥青路面的使用性能,得到青海海西各条干线公路的适用性评价结果。
在分析总结影响路面性能衰变因素的基础上,建立了级配碎砾石基层沥青路面和水泥稳定砂砾基层沥青路面的使用性能衰变模型,并对其使用性能进行了预测。
通过力学分析了级配碎砾石基层沥青路面结构的受力特点以及路面结构参数(模量、厚度)变化时的路面应力应变响应,通过极差和方差方法分析了影响路面结构受力主要因素,从而得到了路面结构设计原则。
分析了影响级配碎砾石材料强度的因素,对级配碎砾石材料级配进行了优化,提出了逐档填充的级配碎砾石设计法；通过加与不加粘土级配碎砾石材料力学性能试验,分析了粘土对级配碎砾石力学性能的影响；研究了碎石掺量对级配碎砾石材料强度特性的影响,得到了不同碎石掺量下材料力学性能。最后针对不同气候和交通荷载等级提出了材料掺量推荐范围及CBR控制范围。
通过现场调研划分了土基等级和交通等级,提出了针对青海海西地区不同交通量和土基等级干线公路路面典型结构。
最后对级配碎砾石基层沥青路面与半刚性基层沥青路面的经济指标进行了量化分析,表明级配碎砾石基层沥青路面经济适用性很好。
This paper launched a systematic research on the performance of the asphalt pavement, the base of which are graded crashed gravel in haixi of qinghai region with dry climate, small traffic and rich resources of gravel.
On the basis of investigation and inspection to Danglenghua Lvhuang and Gemang highway, the asphalt pavement performance with graded gravel and cement stabilized sand gravel are evaluated by using the pavement evaluation systems of our country and COST354,and then the conclusions are made.
Based on the analysis to its performance influencing factors, the model which is avaible to the asphalt pavements with graded crushed stone base and cement graded gravel base is established and the prediction is also made.
Through mechanic analysis, mechanical characteristics of the asphalt pavement structure are identified and the stress and strain re sponse is also learned when the thickness and modulus of the pavement structure change.By appling the variance analysis method, parameters influencing structure stress and strain are analyzed and the pavement structure design principles can be get.
By analyzing factors influening the strength of graded crushed gravel material, grade is optimized and filling graded broken gravel design method is put forward; Through the comparison to the mechanical performance of materials with or without clay,influences of clay to the graded crushed gravel stone mechanical performance are analyzed;Through the analysis to different dosage of crushed stone,influence to the mechanical property is studied and mechanical performance is also obtained.Finally, the material dosage recommendation range and CBR control to different climate and traffic load level are made.
Through field investigation, soil base level and traffic level are divided. Typical highways structure based on different traffic volume and different soil base level is put forward.
Finally, economic index to asphalt pavement with crushed stone base and semi-rigid base is quantitated,which shows that economic applicability of the pavement structure is very good.
