- Abstract:
-
To explore the distribution of internal foree in pavement struetures on stone roadbed, the model wasbuilt. The strueture is made up of4 em AC-13 +6 em AC-20 asphalt surlaee course, eement eonerete, gradedgravel, graded broken stone leveling layer, basement layer of cement conerete and ATB-25. Based on themodel, the elleels of subgrade modulus on tensile stress and shear stress were studied. Results show that changes of subgrade modulus have litle elfeet on pavement strueture stress. Commonly, compressive stress only exists inside the pavement strueture layer. Tensile stress inereases gradually with depth , and tends to zero final.ly. The tensile slress easier appears in the cirele center of load, but it is less. The compressive stress is moreprone to generation at the edge of load round; then, the tensile stress appears in some depth with a bigger value. Shear stress inereases with the loads, and suddenly drops in certain depth; then, gradually it deereasesand tends to be slable.
