PAVEMENT RESPONSE AND RUTTING FOR FULL-SCALE AND SCALED APT
A new accelerated pavement testing (APT) tool has recently been developed lying between relatively inexpensive lab testing and expensive but more realistic full-scale accelerated load testing. The 1/3-scale model mobile load simulator (MMLS3) applies a scaled load on a single tire smaller than a standard truck tire used in full-scale devices and can be used for both lab and field applications. For 2 hypothetical and 8 actual pavement structures at a location where both full-scale APT devices and MMLS3 were used, stress analyses were conducted to: 1) explore a hypothesis of comparable stress distribution; and 2) compare theoretical and measured rutting performance toward validating a performance prediction methodology. For hypothetical pavement structures, the comparable stress hypothesis was upheld. Theoretically calculated rutting ratios based on stress analyses after correcting for differences in loading/environmental conditions were compared with actual measured field rutting ratios. Results were credible and demonstrated that when all influencing factors are considered, rutting performance under full-scale loading can be predicted based on MMLS3 results and stress analysis.
