摘要:
为了完善橡胶沥青应力吸收层设计方法,在分析应力吸收层功能的基础上,针对水泥混凝土路面上加铺沥青层容易出现层间粘结不牢和层间滑移等问题,提出基于层间抗剪强度的应力吸收层材料组成设计方法.研究了沥青种类、沥青洒布量及碎石撒布量对层间抗剪强度的影响,探讨了橡胶沥青应力吸收层设计方法.研究结果表明:层间抗剪强度随碎石撒布量和沥青洒布量的增加均呈先增大后减小的趋势,在碎石撒布量为14 kg/m2,沥青洒布量为2.2 kg/m2时达到最大抗剪强度.推荐橡胶沥青应力吸收层的最佳橡胶沥青洒布量为2.2～2.4 kg/m2,最佳碎石用量为13.5～14.5 kg/m2.
Abstract:
In order to improve the design method of the asphalt rubber stress absorbing membrane interlayer,the asphalt rubber SAMl material composition design method was studied based on the analysis of the functionsof SAMIl and the problems of interlaminar bonding between asphalt concrete overlay and cement concrete pave-ment is not strong and cutting slippage. In this method, the interlaminar anti-shear strength was taken as de-sign index. The paper studied the influence of asphalt types,asphalt spraying content and gravel spreading a-mount on interlaminar anti-shear strength and discussed the asphalt rubber SAMI design method. The resultsshow that the trend of interlaminar anti-shear strength is first increasing and then decreasing with the increaseof gravel spreading amount and asphalt spraying content，reaching the maximum at the gravel spreading a-mount of 14 kg/m3and at the asphalt spraying content of 2.2 kg/ m2. Recommendations for the optimum as-phalt rubber spraying content and gravel spreading amount of asphalt rubber SAMI are 2.2 kg/m3’~- 2.4 kg/m2and 13.5 kg/m2~14.5 kg/ m3respectively.
