摘要:
为了评价应力吸收层沥青混合料的抗剪性能,对应力吸收层沥青混合料进行了不同温度下抗压回弹模量试验和贯入试验的数值分析,分析了试件规格、压头大小、矿料级配等对试验结果的影响.根据数值分析和室内试验结果,验证了应力吸收层沥青混合料贯入试验的可行性,得到适宜的试验条件.分析表明:采用直径和高度均为100 mm的圆柱形静压试件和直径19 mm的压头进行贯入试验时,试验数据稳定,可有效区分应力吸收层矿料级配的优劣.研究成果为应力吸收层沥青混合料的质量评价提供了理论和试验依据.
Abstract:
For evaluating the shear property of stress absorbing layer asphalt mixture, compression reboundmodulus test under different temperatures and numerical analysis were conducted, The inlluence of test conditions such as specimen size and head size and mineral aggregate gradation were discussed, And then the feasibility and appropriate test conditions of penetration test were proposed based on the numerical analysis and testresults. "The results show that: with 100mm diameter and 100mm height static pressure cylindrical specimensand 19mm diameter pressure head, the test data is stable and can effectively distinguish mineral aggregate gra.dation of stress absorbing layer, Conclusion provides theoretical and test basis for quality control of stress ab.sorbing layer asphalt mixture.
