Effects of Truck Tire Pressure on Fatigue and Rutting of Flexible Pavements
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
In the past, damage resulted from load application to highway pavements focused primarily onthe magnitude and frequency of axle loads. In recent years, the effect of increased truck tire pressure on flexible pavements responses has become a subject of great concern. The tire inflation pressure of trucks causes severe deterioration to the pavement and thus reduce its life. This paper aims to evaluate the effects of tire inflation pressure on the pavement response and failure life of pavement. The research uses the ELSYM5 software and pavement materials conditions to estimate the tensile strains occurring under the asphalt concrete (AC) layer and the compressive strains above the subgrade surface. The calculated strain is then utilized to estimate the number of load repetitions to failure due to fatigue cracking and rutting using the asphalt institute (AI) method.
