摘要:
为有效抑制旧沥青路面加铺层结构的层间破坏,建立有限元模型,通过分析水平荷载、加铺层厚度与模量、旧路当量回弹模量、旧路横向开裂等因素对旧沥青路面与加铺层结构层间内力影响规律,进而确定了不同水平摩擦系数对应的旧沥青路面与加铺层结构层间剪应力范围,以及不同加铺层厚度的层间压应力范围,建议在加铺层结构及层间材料设计时取最不利状态的层间内力.研究结论对沥青路面加铺层结构设计及层间材料技术指标要求具有参考价值.
Abstract:
In order to effectively suppress the interlayer failure of the old asphalt pavement plus pavement structure, a finite element model is established, and the influence law of the internal forces between the old asphalt pavement and the paving structure is determined by analyzing the horizontal load, the thickness and modulus of the additional layer, the equivalent rebound modulus of the old road, and the lateral cracking of the old road on the internal forces of the old asphalt pavement and the paving structure, and then determine the range of interlayer shear stress of the old asphalt pavement and the paving structure corresponding to different horizontal friction coefficients, and the interlayer compressive stress range of different pavement thicknesses. The research conclusion has reference value for the design of asphalt pavement plus paving structure and the technical index requirements of interlayer materials.
