MONITORING PROGRAM CRCP HIGHWAY PAVEMENT: INTERIM PERFORMANCE EVALUATION

Abstract

This paper presents the first findings and analysis of data collected in a monitoring program of a newly constructed continuous reinforced concrete highway pavement initiated in 1997. This monitoring program was set up as it was felt that pertinent data were not available to make an objective comparison in the process of deciding between an asphalt and a continuos reinforced concrete pavement structure. Over a ten-year period a wide range of data will be collected such as construction data, including laboratory results, traffic, temperature (air and pavement), structural condition, detailed visual inspections, surface friction, roughness, noise level, joint movements and other relevant information. All data and reports will be stored in a database to facilitate easy access and quarrying. The data collected over the first three years and the analysis performed have resulted in a detailed insight into the as-built parameters, development of stresses based on the change in temperature gradients and the traffic load spectrum. At this stage of the monitoring program conclusions can already be drawn based on the information gathered to date as processed in a study performed at Delft University of Technology.
