Study of New AASHTO Pavement Design Guide. Phase 1
A comparative study of the AASHTO Interim Guide and the 1986 AASHTO Guide is described. A sensitivity analysis is presented which indicates the relative importance of variables used in the 1986 Guide. This allows for a more informed selection of variables. Comparisons of designs using both guides is presented. Based upon present design procedures used by the South Carolina Department of Highways and Public Transportation (SCHDPT) and performance of pavements constructed using the Interim Guide, it appears that benefits can be obtained by using the new guide which uses the resilient modulus as a basis for establishing a soil support value. The SCHDPT can phase in the use of the 1986 Guide with full implementation in several years as correlations of resilient moduli and other soil properties are developed. Summaries of questionnaires gathered from most states are presented.
