- 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.
