针对不能封闭交通,对水泥稳定碎石进行正常养生成型的路段,对悬浮密实型和骨架密实性水泥稳定碎石在不养生条件下的力学性能分析,提出骨架密实型水泥稳定碎石在不养生条件下成型的可行性。并通过实际铺筑试验路,检测其弯沉、模量变化指标,发现铺筑24h后,水泥稳定碎石强度变化最大,提出采用弯沉检测的方法来保证快速铺筑上部结构层后,水泥稳定碎石达到设计强度的控制方法。
Aiming at the sections that can not be closed traffic and normalizing the shape of cement stabilized macadam, the mechanical properties of suspended solid and skeleton dense macadam under untempered conditions are analyzed. Feasibility of molding under conditions. And through the actual paving test road, testing the deflection and modulus change index, found that paving 24h after the greatest changes in the strength of cement stabilized macadam, the use of deflection detection method to ensure that the rapid paving of the superstructure layer, the cement Stabilized gravel to achieve the design strength of the control method.
