Long-term monitoring of pavement sections on the N3 Toll Concession network

The level of data collection on the N3 Toll Concession network provides a valuable opportunity for detailed long-term monitoring of the actual performance of their pavement structures. This is important in predicting future performance and in devising a cost efficient management strategy. As part of an extensive monitoring program, seven short (< 2 kilometre) sections from the network are monitored on an on-going basis. The sections include pavements reconstructed with BSM-emulsion and lightly cemented bases. All the available materials data are used to understand the type and condition of the materials, and layer thicknesses. The data are also used to classify the materials, and to construct a model of the pavement structure on which structural capacity estimates are based. The difficulties associated with constructing a pavement model and predicting structural capacity are discussed. An in-depth monitoring assessment using the annual rutting, roughness and deflection data is completed, and the performance is monitored with the cumulative traffic carried. This paper discusses the use of the available data to obtain a detailed understanding of the actual pavement performance, and the usefulness of the information.
