PAVEMENT PERFORMANCE INVENTORY IN MICHIGAN

A STRENGTH INVENTORY WAS RECENTLY CONDUCTED IN MICHIGAN ON THE EXISTING TRUNK LINE SYSTEM. A REVIEW OF DESIGN AND CONSTRUCTION HISTORIES WAS CONDUCTED ALONG WITH A STUDY OF FOUNDATION SOIL CONDITIONS. THE RESULTS OF THE STUDY WERE SUMMARIZED ON THE MAP OF THE STATE TO BETTER PICTURE THE PRESENT STRENGTH STATUS AND MAKE THE RESULTS USABLE TO MAINTENANCE, PLANNING AND PROGRAMMING ENGINEERS. THE FOLLOWING FOUR CLASSIFICATION CATEGORIES WERE USED: (1) NO SEASONAL RESTRICTION -- PAVEMENT AND SUBGRADE ADEQUATE FOR YEAR-ROUND SERVICE, (2) NO SEASONAL RESTRICTION -- PAVEMENT DESIGNS WHICH COMPENSATE FOR SEASONAL LOSS OF STRENGTH, (3) SPRING LOAD RESTRICTION REQUIRED -- PAVEMENT DESIGNS WHICH DO NOT COMPENSATE FOR SEASONAL LOSS OF STRENGTH, AND (4) SPRING LOAD RESTRICTIONS REQUIRED -- PAVEMENT DESIGN INADEQUATE FOR LEGAL AXLE LOADS AT ALL TIMES. THE SUMMARY MAP WILL ALSO SERVE AS A BASE MAP FOR OVERLAYS WHICH WILL SUMMARIZE ALIGNMENT, CROSS-SECTION AND WEARING COURSE INFORMATION. THIS INFORMATION, PLUS STRENGTH AND TRAFFIC DATA, SHOULD FORM AN EXCELLENT BACKGROUND OF ORGANIZED FACTS NEEDED TO DEVELOP A TRUNKLINE SYSTEM ADEQUATE FOR YEAR-ROUND SERVICE.
