Abstract:This relatively short-term project was initiated in order to perfect installation, operation, and maintenance practices necessary for continued accurate and reliable operation of a computerized Weigh-in-Motion system which will be used to gather truck weight data in a long-term study to improve flexible pavement design.
A complete Weigh-in-Motion System installation was med on U. S. Highway 190 near Baton Rouge and operated for approximately three months, during which time 173 trucks varying in weight and number of axles and traveling at various speeds were correlatively checked for total weight against Louisiana Department of Highways enforcement scales located nearby. Accuracy of the system's speed determination capability was checked at the beginning and end of the three-month operating period using a hand-held radar unit as reference.
The goals of the study were attained. Five operators received training and experience in operating, maintaining, and installing the equipment. The accuracy and repeatability of the System was demonstrated by correlative measurements, and the system now stands ready along with a trained crew to be used in the ten-year Louisiana Experimental Base Study.
