| 摘 要： | 级配碎石作为沥青路面基层,容易发生剪切破坏.选取三种典型级配碎石路面结构,从理论上分析了级配碎石层受到的最大剪应力,并通过试验测定了级配碎石的抗剪强度,通过控制沥青面层厚度来保证级配碎石层不会发生剪切破坏.

| Abstract: | As base of asphalt pavement,the grading macadam is easy to yield the shear demolition.The paper takes three kinds of typical grading macadam pavements,and analyzes the maximum shear stress which is borne by a grading macadam base from theory,moreover determines the shear resistance of grading macadam by test,furthermore ensures the grading macadam base from shear demolition through controlling the thickness of asphalt surface. |
