Abstract: Longitudinal joint cracks between asphalt mats are common problems in asphalt pavements and often deteriorate faster than other areas. The cracks resulting from the deteriorated longitudinal joints are very important for determining the performance life of the asphalt pavements. Cracks in the longitudinal joints allow the ingress of water into the pavement leading to further disintegration. In the urban areas asphalt paving is often done in stages to facilitate traffic control. In most widening projects, the lane marking does not coincide with the edge of the pavement. This results in traffic loads traveling at variable distance from the edge although the most common assumption in modern flexible pavement evaluation and design is that the wheel path is located about 50-100 cm from the edge of the pavement. It is suspected that the loading near the edge is one of the primary causes of longitudinal joint deterioration. In this study, mechanistic analysis with the finite element (FE) technique has been conducted to predict pavement response at the longitudinal joint under the truck load at different lateral positions relative to the joint. The FE analysis results showed that the position of the truck significantly affects the strains at the longitudinal. Tremendous increase in tensile strain was observed as the truck position nears the longitudinal joint. Maximum critical strains occur when the truck is positioned right at the longitudinal joint. The lane marking should be done in such a way that the right wheel path is located about 53 cm from the longitudinal joint.
