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.

An airfield pavement investigation was performed in November 1995 at Robert Gray Army Airfield, Fort Hood, Texas, to develop information pertaining to the structural adequacy of the airfield pavements for continued use under current mission and upgrading of the pavements for mission changes. The pavement surface condition was evaluated by use of the pavement condition index (PCI) condition survey procedure, and a nondestructive evaluation procedure was used to determine the load-carrying capability of the pavements and overlay requirements for continued use of the pavements under current missions. Results of the evaluation are presented including: (a) a tabulation of the existing pavement features, (b) the results of the nondestructive tests performed using a falling weight deflectometer, (c) the PCI and rating of the surface of each pavement feature, (d) a structural evaluation and overlay requirements for rigid and flexible pavement (4,900 passes and 2,600 passes of the B-747 aircraft, respectively), (e) the pavement classification number for each pavement facility, and (f) maintenance and repair recommendations based on the structural evaluation and condition survey.
