基于FWD的连续配筋复合式沥青路面结构性能分析

为研究连续配筋复合式沥青路面(CRCP)的结构性能,对CRCP、半刚性基层沥青路面(SMAC)及两者过渡路段做动态弯沉测试。分析发现,CRCP的整体结构强度、面层强度和基层强度均较高,且路段内各测点结构强度较为一致;SMAC及CRCP与SMAC的过渡区路段的整体结构强度、面层强度和基层强度偏低,且路段内各测点处结构强度差异较大。经过9个月余的运营,CRCP结构性能仍较为稳定,而SMAC结构整体强度相对降低较快。

Structural Performance Analysis of Continuous Reinforced Composite Asphalt Pavement Based on FWD

To study the structural performance of continuous reinforcement composite asphalt pavement(CRCP),dynamic deflection tests were carried out on CRCP,semi-rigid base asphalt pavement(SMAC)and their transition sections.It was found that the overall structural strength,surface strength and base strength of CRCP were high,and the structural strength of measuring points in the CRCP section were relatively consistent;while the overall structural strength,surface strength and base strength of SMAC and the transition section of CRCP and SMAC were relatively low,and the structural strength within test sections were quite different.After more than 9 months of operation,the performance of CRCP structure is still relatively stable,while thereduction of overall strength of the SMAC structure is relatively more fast.
