• Abstract:
  The strategic plan for establishing a vehicle weight monitoring net across Texas calls for deploying two ; technology types – piezoelectric and bending plate systems, and seeks to install weigh-in-motion (WIM) ; systems in roadways that are under new construction or re-construction. Because the goal is to provide ; accurate truck weight data for pavement design, the strategic plan prefers deploying WIM installations on ; 500-ft continuously reinforced concrete pavements. While these pavements have, from experience, provided ; suitable stable foundations for WIM sensors, building a continuously reinforced concrete pavement is ; expensive. This project aimed to find less costly but equally viable alternatives for deploying WIM ; installations by developing guidelines for finding sections within existing asphalt concrete pavements that ; provide the level of smoothness, pavement support, and projected service life deemed suitable for weigh-inmotion ; sites, particularly for installations that use piezoelectric technology. Additionally, the project sought ; to evaluate the use of solar cells to power WIM systems, and wireless alternatives for data communication. ; These alternatives become particularly relevant in areas where bringing electrical and telephone wires to the ; site would add significantly to the cost of the WIM installation.
