摘要
用沥青大碎石柔性基层对老路面进行补强,可以有效地提高路面的使用性能,减少反射裂缝的产生,延长道路的使用寿命。本文对沥青大碎石柔性基层用加德士AH-70号、SBS改性沥青和MAC改性沥青分别进行试验,通过试验结果和经济性能对比分析,找到适合这种结构的最佳沥青。
The pavement performance can be improved by applying the large stone asphalt mixes flexible base to the old road strengthening in order to reduce reflect of the cracks and prolong the service life of the road. CALTEX AH-70 #, SBS and MAC modified asphalts are used to test respectively and the best asphalt suitable to this structure is fund by the test results and economy and performance compared and analyzed.
