Relationship between traffic density and pavement deflections

Abstract

Traffic density is one of the most important parameters to consider in road construction. The presence of different components in road construction makes it essential to know the individual layer and inter-layer behaviors. One of the physical factors that plays a major role in these layers is their displacement, which varies depending on the type and engineering properties of these layers. Road damaging is inevitable as different deformations also trigger mismatching. Due to incompatibilities between layers, the number and content of repairs are also high than they should be, which increase maintenance costs. Therefore, it is important to conduct experimental and theoretical studies on this subject. Although the effect of traffic density on a single layer has been studied, there are not many studies investigating the co-movement of different layers. Therefore, the aim of this paper is to provide a holistic approach to this subject by compiling different studies.
