Necessary Assessment of Use of State Pavement Management System Data in Mechanistic-Empirical Pavement Design Guide Calibration Process

摘要: Calibration and validation of the Mechanistic-Empirical Pavement Design Guide (MEPDG) for state department transportation (DOT) networks requires detailed information a variety pavement inputs. The biggest database resource that most states possess is their management system (PMS). It understandable any DOT to maximize use this greatest extent possible. However, before uses PMS data in MEPDG calibration, it important careful comparison be made equality measurements, data, so forth with national Long-Term Performance (LTPP) values. purpose paper review possible differences between several key found LTPP database. Arizona Department Transportation (ADOT) are used purpose. specific variables examined deal distress type (rutting, cracking, roughness) nondestructive deflection testing (NDT) ...
