Title: SELECTION AND PRIORITISATION OF MAINTENANCE WORKS ON MAJOR ROADS IN ENGLAND
Abstract: The new Pavement Management System (HAPMS), implemented by the Highways Agency, is used to manage major maintenance works on all carriageway pavement types on the trunk road network in England. The system is used to manage the whole road pavement asset with a key component of that process being the prioritisation, based on whole life costs, of the separate treatment options on the parts of the network under consideration for major maintenance works in each year. Treatment options, on each pavement length, are automatically generated by the system and other options may be defined by the engineer. In the system, major maintenance requirements for the budget year and all future years in the analysis period are interpreted from the predicted future condition of the length of the road and are representative of the treatments that would be selected by practising highway managers. The system includes rules that reflect that decision making process. Pavement condition measurements are used to identify the maintenance requirements in the budget year, including the option of the minimum possible treatment. Projection of the pavement condition is based on the trend in condition while taking into account the age of the pavement, the traffic to be carried and the expected future maintenance treatments. The costs of the proposed maintenance works and the later maintenance works required during the whole life analysis period, together with the costs to the road user incurred during maintenance works, are combined to produce an indicator of the economic effectiveness for each proposed maintenance option. These economic indicators are analysed to identify the set of maintenance options that provide the best use of the budget available for the year. For the covering abstract see ITRD E108018.
