• Abstract:
  Truck weight data are required for pavement and bridge design, truck size and weight enforcement, and the development of administrative policy and legislation. The efficient collection and analysis of these data require that truck weighing-in-motion (WIM) equipment be used. Unfortunately, the high cost of these devices (greater than $50,000 per unit) has prohibited the large-scale implementation of WIM technology. Lower cost WIM systems are also necessary to provide new or expanded data required by both the Long Term Pavement Performance (LTPP) monitoring element of the Strategic Highway Research Program (SHRP) and implementation of the provisions of the recently issued Federal Highway Administration (FHWA) Traffic Monitoring (TM) Guide. Several possible technologies exist for low-cost WIM systems. One of these, piezoelectric cable, was investigated in a research effort jointly sponsored by the States of Iowa and Minnesota and FHWA and in other work in the State of Washington and several European countries. A second approach is an inexpensive capacitive weighmat WIM sensor and associated electronics developed for FHWA. A third alternative is a reduced cost configuration of the bending plate WIM transducer manufactured and distributed by the PAT Equipment Corporation. Each of these was evaluated in this study to determine its usefulness in providing effective truck weighing devices at a cost that would allow widespread implementation of in-motion truck weighing programs in Texas.
