粉胶比对浇注式沥青胶浆高低温性能的影响

摘要

This paper chooses 9 tiller-asphalt ratios to study change rules of high & low temperature performances of cast asphalt mastic at different filler-asphalt ratios. The result shows that increase of fillerasphalt ratio can remarkably improve high-temperature stability of cast asphalt mastic, while increase of filler-asphalt ratio can improve crack resistance at low temperature. Therefore, adoption of reasonable filler-asphalt ratios can guarantee balance between high-temperature performances and low-temperature performances of cast asphalt mastic.%选用9种粉胶比,研究不同粉胶比下浇注式沥青胶浆的高低温性能变化规律.结果表明:提高粉胶比可显著提高浇注式沥青胶浆的高温稳定性,而降低粉胶比可提高浇注式沥青胶浆的低温抗裂性.因此,采用合理的粉胶比可保证浇注式沥青胶浆高温性能与低温性能的平衡.
