Long-Range Rehabilitation Plan for US 59 in the Lufkin District of Texas, Final Report
In this report, the authors briefly introduce Project 7-987 and then describe what they intend to do in the future with US 59. The authors have organized US 59 traffic data in terms of Texas Department of Transportation (TxDOT) classified sections, the pavement types defined previously in CTR Report 987-1, and the mile markers along the roadway. A general logistic model for the development of reflective and fatigue cracks in pavement surface is proposed and verified using the information collected during the last eight conditions surveys of the test sections. The rut depth data along the wheelpaths in various test sections are found to follow the Gamma distribution. The raw average rut depth for various test sections have been plotted against the amount of traffic loadings placed on pavement. The irregular behavior of the rut data is observed for various test sections in the first 2-year period. Analytic models predicitng development of reflective cracks, fatigue cracks, and rut depth in pavement surfaces are calibrated using the field data. Then, two computer programs, one for flexible pavement and the other for rigid pavement, are generated for use in planning the future rehabilitation of US 59. Examples using the programs are demonstrated and reasonable results are obtained. Overlay strategies for different control sections along US 59 are proposed based on the AADT information.
