ABSTRACT
Design standards for new road construction are based on the expectation that necessary maintenance will be carried out periodically to deal with the inevitable deterioration caused by traffic loading, climatic effects and other deleterious influences. Consequently, road maintenance is a fundamental necessity, as important as the original road provision. The maintenance of the roadway asset must, additionally, be planned, designed and carried out in the knowledge that the road is there to provide a high level of service to users who, rightly, expect their needs to be met even when activities are being carried out on the network. Moreover, all maintenance has to be carried out with full regard to the requirements of governmental legislation which affects many aspects of the work involved.
