摘要：	Truck size and weight issues have been at the center of highway cost allocation studies, pavement thickness and geometry design standards for separate jurisdictions, and vehicle configuration regulation. Longer trucks and increased axle weights have been proposed to improve industry efficiency, thicker pavements to reduce road system maintenance costs, and alternate pavement designs with modified taxing and licensing structures to encourage a more effective national transportation infrastructure. This study provides information about the issues involved through models of vehicle dynamic loads and their effect on selected pavement structures. A summary of studies related to safety and vehicle performance details some critical issues facing highway engineers and transportation planners.
