分析规范设计方法存在的不足 ,提出了基于路用性能的高性能二灰稳定碎石集料的级配范围和设计方法—— HPL FA设计方法。并通过设计实例和试验工程进行了验证 ,证明使用 HPL FA方法设计的基层混合料具有优良的综合路用性能 ,能够有效地防止由于基层引起的路面早期破坏
By analyzing the shortcomings of the standard design method, the range and design method of gradation of high-performance lime-flyash stabilized macadam aggregates based on road performance are put forward - HPL FA design method. And verified by the design example and the pilot project that the grassroots mixture designed by using the HPL FA method has excellent comprehensive road performance and can effectively prevent the early damage to the road surface caused by the grass roots
