MINNESOTA ROAD RESEARCH PROJECT: LOAD RESPONSE INSTRUMENTATION INSTALLATION AND TESTING PROCEDURES. FINAL REPORT

This report presents the step by step installation and testing procedures developed for the load response instrumentation at the Minnesota Road Research Project (Mn/ROAD). Load response instrumentation measures such parameters as strain, deflection and pressure in the pavement layers from dynamic axle loadings. The test procedures presented were performed immediately before and after paving to check for any gross malfunctioning of lead wires or sensors. The procedures presented do not include any accuracy tests. Initial survivability of the sensors is discussed as are probable causes for failures.
