水泥稳定碎石半刚性基层强度高、刚度大、整体稳定性良好,但容易产生裂缝;级配碎石柔性基层排水能力强、抗裂性良好,但强度低、稳定性差;结合两者的优缺点,提出低水泥剂量稳定级配碎石基层,本文结合具体的公路工程,利用低水泥剂量稳定级配碎石基层铺筑试验段,并对其进行路面表面平整度、裂缝、弯沉试验的检测,详细论述了低水泥剂量稳定级配碎石基层的路用性能。
The semi-rigid base course of cement stabilized macadam is characterized by high strength, great rigidity and good overall stability, but is prone to cracks. The graded macadam base has strong drainage capacity and good crack resistance but low strength and poor stability. Shortcomings, the paper proposes a low-cement-stabilized grade graded crushed stone base. In this paper, with the concrete road project, the test section is paved with a low-cement-stabilized graded graded base, and the surface roughness, Testing, detailed discussion of low cement dosage stabilized graded road base performance.
