ECONOMIC ASPECTS OF HIGHWAY MAINTENANCE

The total maintenance decision process is considered by the author to have five stages. (1) inspection and categorisation of the highway network, (2) consideration of alternative forms of treatment to rectify observed defects, (3) preparation of short list of sites for works, (4) assessment of priorities and (5) preparation of programmes. Each of these stages is discussed at length by reference to the allocation of economic resources to meet the requirements for cyclic maintenance activities relating to the operational efficiency of the highways, and structural maintenance activities concerned with the road structure itself. The cost effectiveness of highway maintenance practice is considered in relation to the results obtained from the flexible construction of the Alconbury Hill experiment, and the 1977 Kent mini-chart survey. The March and chart systems of assessing the structural maintenance needs of highways are considered, and a series of depreciation curves are presented as an aid to the understanding of maintenance investment concerned with remedial treatments such as surface dressing and resurfacing to maintain the design life of the road. /TRRL/
