註釋

This report presents a thorough study on the effects of temperature and moisture on the load response of low-volume roads. The procedures developed herein can be used to formulate temperature and seasonal adjustment factors for low-volume roads and to estimate when and where seasonal load restrictions should be applied. Field studies were performed on two light pavement structures at the Texas Transportation Institute Research Annex. The tests consisted of taking pavement layer temperatures and Falling Weight Deflectometer deflection readings at hourly intervals throughout the day. In addition, six Farm-to-Market roads in different regions of the state of Texas were monitored monthly to evaluate temperature and moisture effects on pavement moduli.
