Abstract
Characterization of pavement layer properties and responses under traffic loads, local materials, and weather conditions in Thailand is essential for accurate pavement performance prediction, pavement deterioration models development, as well as pavement management system. This study presents the flexible and rigid pavement responses for long-term pavement monitoring in Thailand. Two pavement sites situated near permanent weigh station and weigh-in-motion system on Highway No. 4 in Nakorn Phathom and Rachaburi provinces were instrumented with pressure cells, strain gauges, thermocouples, and moisture sensors. These test sections represented typical pavement structure in Thailand according to the Department of Highways design standard and specification. Field pavement response and environmental data including stress, strain, moisture, temperature from the embedded instrumentation were monitored since late 2017.
