Abstract
For ensuring objectivity and impartiality in budgetary allocations of road pavements, a new index to quantify the rehabilitation demands of a corridor is required. Under the pavement inspection guideline, there are diversified methods of inspecting and the road administrators can make decisions of which one to use by taking into consideration the information content about surface distress and cost of them. In this paper, a method for setting a budget allocation ratio in proportion of each corridor's quantity allocated to state three is proposed. Since a quantity allocated to state three is a condition state rate for state three, which is called “percent defective”, multiplied by a corridor's total quantity, calculation methods of the percent defective for corridors are clarified corresponding to the diversification. Finally, calculation methods' influence on the budget allocation ratio is investigated by a case study dealing with the primary road in the real world.
