硅灰多孔水泥稳定碎石基层性能的试验研究

Experimental Study on Performance of Silica Fume Porous Cement Stabilized Macadam Base

传统水泥稳定碎石密实性较好,透水能力较弱,容易造成结构层损坏,而多孔水泥稳定碎石可以很好地解决这一问题。本试验在多孔水泥稳定碎石中掺入硅灰,研究掺加不同种类硅灰对多孔水泥稳定碎石基层的影响,研究其主要路用性能:无侧限抗压强度、动态回弹模量、弯拉强度和透水性。

The traditional cement stabilized macadam has good compactness and weak water permeability,which is easy to cause damage to the structural layer,and the porous cement stabilized macadam can well solve this problem.In this test,silica fume is mixed into the porous cement stabilized macadam to study the impact of different types of silica fume on the porous cement stabilized macadam base,and its main road performance:unconfined compressive strength,dynamic resilient modulus,flexural tensile strength and water permeability.
