Analysis Relating to Pavement Material Characterizations and their Effects on Pavement Performance

摘要: This report presents the analysis conducted on relating pavement performance or response measures and design considerations to specific layers utilizing data contained in Long Term Pavement Performance Program National Information Management System. The goal of this research activity was enhance implementation use 1993 AASHTO Design Guide through improved materials characterizations. Specifically, focus identify differences that exist between laboratory measured backcalculated resilient moduli; determine applicability C values, drainage coefficients, relative damage factors are included Guide; provide procedures adequately consider seasonal variation material properties as related flexible designs. Based these results, pamphlets have been prepared support Guide. These documented other reports. results reported here form basis background for those pamphlets.
