Aspects of the PSMC001 network performance: rehabilitation projects and general network condition indicators

This paper documents an assessment of some aspects of network and project level performance for the PSMC 001 contract. Current performance base contracts are moving toward a 25 year design life criteria for assessing contract rehabilitation performance. One of the main problems with this trend is that current design methods have not been proven to be adequate. These methods do not necessary provide a guarantee that the rehabilitation will deliver the expected performance in the field. In order to test current methodologies, a case study of the PSMC 001 contract has been used to assess actual performance and effectiveness of rehabilitation. The analysis showed that the inclusion of a post-construction assessment of structural capacity is definitely meaningful and contributes to monitoring conformance to the intent of the contract. It is of special concern that – despite a significant proportion of the network being rehabilitated within the maintenance period – there has been no appreciable improvement in the network condition as far as roughness and rut depth is concerned. Performance of these roads suggest a need to calibrate or re-assess aspects of the FWD analysis and ME methodology used to assess the post-construction structural capacity. (a)
