摘要/Abstract

摘要： 选用SBS改性沥青,通过沥青胶浆低温黏结强度定量测试技术,研究了在不同低温条件下不同粉胶比对沥青胶浆低温黏结强度的影响机理,并确定了最佳粉胶比.研究结果表明:低温环境,粉胶比对沥青胶浆的低温黏结强度变化规律有显著影响.合适的粉胶比能够提高沥青胶浆的低温黏结强度.大粉胶比会产生填料附聚现象,截面附加破坏点基数增加,导致沥青胶浆低温黏结强度显著下降.此外,环境温度降低,沥青基体强度有所提高,但当温度低于沥青脆化点后,基体发生脆化,从而导致低温黏结强度显著降低.最佳粉胶比的确定应结合当地的低温条件,综合考虑沥青基体的黏结强度,沥青基体脆化状态及沥青填料界面强度效应.

Abstract: The effect of filler-to-bitumen ratio on the low-temperature cohesive strength of SBS modified asphalt mortar was studied using quantitative testing technology. Two control variables, filler-to-bitumen ratio and temperature, were selected in the experiments. Results show that the change rule of the low-temperature cohesive strength is significantly influenced by both the filler- to-bitumen ratio and the low temperature environment. Appropriate filler-to-bitumen ratio can improve the low-temperature cohesive strength of asphalt mortar. Excessive content of mineral power fillers will produce filler agglomeration, causing additional damage points, which lead to significant decrease in the strength. The cohesive strength of the asphalt matrix increases as the environment temperature decreases. However, when the temperature is below the asphalt's embrittlement point, the asphalt matrix can be embrittled, which significantly attenuates the cohesive strength of the asphalt matrix. Therefore, the cohesive strength of the asphalt matrix, its embrittlement state and the effect of the contact interface strength of asphalt filler should be comprehensively considered in determining the optimal filler-to-bitumen ratio. Moreover, these factors should be combined with local low temperature conditions.

Key words: road engineering, low-temperature cohesive strength, filler-to-bitumen ratio, asphalt matrix strength, mineral powder filler agglomeration
