A Review Paper on Pavement Surface Unevenness Evaluation

The interaction between road pavement and vehicle tyre influences many factors, directly or indirectly related to safety and efficiency of road exercise. The geometry of a paved road surface is usually described by means of specific characteristics or properties like texture, the evenness or the roughness and deflection and these interaction effects determined some functional performance of pavement that are related to the correct and the reliable use of road infrastructure especially in terms of users safety and comfort. For these reasons it is important to be able to determine or measure the pavement surface unevenness conditions in order accurately developed the design and construction activities as well as to plan and realized the most appropriate pavement management and evaluation program when the infrastructures are subjected to the wear due to traffic and environmental actions. Pavement evaluation is a technique of assessing the condition of a pavement, both structurally and from the point of view of surface characteristics relatives and their economic evaluation.
