【摘要】：针对普通微表处混合料抗疲劳性能、低温抗裂、降噪环保差等问题,提出采用橡胶粉与聚丙烯纤维复配方案,并研究了橡胶粉等量替代矿粉条件下不同橡胶粉掺量对橡胶粉-纤维微表处混合料的施工性能、长期使用性能以及降噪效果的影响。基于以上研究本文推荐采用2.5‰聚丙烯纤维+3%~5%橡胶粉复合改性方案。
[Abstract]:Aiming at the problems of anti-fatigue performance, low temperature crack resistance and poor environmental protection of common micro-surfacing mixture, a scheme of blending rubber powder with polypropylene fiber is put forward. The effects of different rubber powder content on the construction performance, long-term use performance and noise reduction effect of rubber powder fiber microsurfacing mixture under the condition of replacing mineral powder with rubber powder were studied. Based on the above research, the compound modification scheme of 2.5 鈥，
