Analysis of Stress and Strain for Semi-Rigid Asphalt Pavement Based on Accelerated Loading Test

Abstract:

Through the construction of cement stabilized macadam and lime-fly ash stabilized macadam road, and strain gauges, vertical stress sensors and temperature sensors were laid in the pavement during construction. Pavement structure dynamic stress, strain, deflection and pavement temperature were collected. The correlation between pavement temperature and structural dynamic response was analyzed. The results showed that, tensile strain of semi-rigid base layer was less affected by temperature; structural deflection was great affected by the thickness of semi-rigid base. After a certain number of repeated loads, the delay rate of tensile strain of semi-rigid base layer increased first and then slowly decreased.
