Pavement Damage Functions for Cost Allocation. Volume 3. Flexible Pavement Damage Functions Developed from AASHO Road Test Data

摘要

Flexible pavement damage functions for rutting and serviceability loss were developed from a representative subset of AASHO Road Test data consisting of 76 test sections. The primary purpose of this limited project was to check out and validate the use of a combined mechanistic and empirical modeling approach to develop damage functions that were used in the recent cost allocations studies. Load equivalence factors were also developed from the damage functions and compared to other LEF's from previous studies.
