1、前言高等级公路路面结构一般分为面层、基层(包括底基层)及垫层。其中基层主要承受由面层传来的车辆荷载垂直力并把它扩散到垫层和土基中,因此,基层应具有足够的强度和刚度,也应具有足够的平整度和水稳定性,并受温度、湿度变化影响较小。石灰、粉煤灰(二灰)稳定碎石在目前高
1, Foreword High-grade highway pavement structure is generally divided into surface layer, grassroots (including the grassroots) and cushion. The grassroots mainly carry the vertical force of vehicle loads from the surface layer and spread it to the cushion and soil foundation. Therefore, the grass-roots level should have sufficient strength and rigidity, and should have sufficient flatness and water stability By the temperature and humidity changes less affected. Lime, fly ash (lime) stable macadam is currently high
