摘　　要：针对二灰砂砾在实际使用中存在离析、早期强度较低、耐冲刷性一般等缺点,通过合理级配设计使得二灰砂砾具有良好的路用性能是保障其应用的关键。通过K法对二灰砂砾配合比优化,经过室内测试分析,提出了基于性能设计原则的二灰砂砾混合料合理的配合比。Aiming at the disadvantages such as segregation in lime-fly-ash gravel,low early strength and poor abrasion resistance,reasonable proportion design which can give good road performance to lime-fly-ash gravel is the key point to its application.Reasonable proportion of lime-fly-ash gravel mixture is proposed based on performance design principle through lime-fly-ash gravel proportion optimized by K method and indoor test and analysis.
