Rigid Pavement Condition Survey Handbook PDF Download

Pavement condition surveys are necessary to evaluate the effect upon pavement life and service caused by various factors such as subgrade soil of the various classifications, subgrade densification, subgrade treatments, subgrade drainage, subbase materials and methods of placing, pavement materials, pavement design, pavement construction methods, traffic, maintenance materials and methods, and climatic conditions. Pavement condition is logically measured for Portland cement concrete pavements by the condition of joints and cracks, condition of the surface, and the amount of cracking and breakage. In addition, it is logically measured for pavements of the flexible type by the amount of cracking, type of cracking, raveling, rutting, shoving, settling, bleeding, and the area and depth of patches. Skid resistance and degree of bumpiness are pavement condition factors for both rigid and flexible pavements. Various types of condition surveys are outlined and suggestions made for making them.
