Analysis of highway maintenance cost elements

The trend toward highway maintenanceovershadows construction because of the high benefit and low capitalinvestment involved. There are, however, constraints on theavailable maintenance budget to satisfy all the network requirements. So, available budget must be efficiently used and controlled to get the most benefit for the whole network. The current funding for highway onstruction and maintenance works is not always related to need. The relationship between the available funds and those needed to provide an acceptable level of performance does not exist.Even if the budget is estimated, its foreign component and its effect on the whole economy is not known.Because both execution process and prices are changing with time, hence highway construction and maintenance costs must be estimated periodically. Therefore, some sort of relationship between the available funds and those needed should be established. Moreover, the available budget has tobe effectively used to get the most benefit for the whole network.In order -to establish this relationship, cost analysisof different highway construction items and maintenance
