Oil field truck traffic is identified in this paper as a special highway user, and an estimate of the annual cost associated with reduced pavement serviceability on thin surface-treated pavements is provided. Identification of oil field traffic through site-specific observation provides the basis for the investigation. The study includes a description of traffic during the development of an oil well, an estimate of reduced pavement service under these operating conditions, and an estimate of increased annual pavement cost due to oil well traffic. Three main components of the analysis procedure include a pavement analysis, a traffic analysis, and an estimate of traffic generated by an oil well. The AASHTO concept of pavement serviceability was used to determine a reduction in pavement service life due to this concentrated traffic demand. Photographic documentation of the evolution of an oil well provided both an axle count and a description of the physical characteristics of the vehicles. Axle weights were estimated by using standard state loadometer data. Estimates indicate a 50 percent loss of service life due to this special-use industry (considering only one well) as compared with the expected service life if the road had continued to serve its intended purpose. An increased annual cost of $16,500/km was determined for a low-volume, light-duty pavement section. The increase in annual cost is a separable cost attributable to the concentration of a special-user activity. (Author)
