研究了悬浮密实型、骨架密实型以及悬浮骨架密实型水泥稳定碎石的施工性能、力学性能以及干缩抗裂性能,探讨了级配变化对水泥稳定碎石综合性能的影响规律。结果表明,悬浮密实型级配具有较好的工作性能,骨架密实型级配具有较好的力学性能,悬浮骨架密实型级配则具有更好的综合性能,尤其是优良的抗裂性能。 The construction performance, mechanical properties and shrinkage cracking resistance of suspended solid, solid skeleton and suspended solid cement stabilized macadam were studied. The influence of gradation on the comprehensive performance of cement stabilized macadam was studied. The results show that the suspended dense gradation has good working performance, the compact skeleton of the skeleton has good mechanical properties, and the dense skeleton of the suspended skeleton has a better overall performance, especially the excellent crack resistance.
