The definition of term pavement management and the three strategies to develop restoration and rehabilitation programs used by public agencies.
Explanation of Solution
Pavement management is a systematic method for maintaining, upgrading, and in operation physical pavement assets during a cost- efficient manner. The method combines applications of established engineering principles with theory of economic and sound business practices, therefore reassuring an organized and approach of scientific to decision making.
The term pavement management refers to the different kinds of strategies that may be used to choose a restoration of pavement and rehabilitation policy. At one end, there's the "squeaky wheel" approach, whereby projects are selected because they have created the highest attention.
At the other end, there is a system whereby roads of all are repaired on a regular schedule, for which there is no object of money.
The three strategies to develop restoration and rehabilitation programs used by public agencies are given below.
- Pavement rehabilitation or rehabilitation programsare plans that includes minimum standards for pavement acceptable condition and required to establish the type treatment which is required to maintain a minimum level of serviceability and the time frame for the completion of project.
- Rehabilitation program strategies include consideration of items such as condition of pavements, first cost, maintenance of annual, user costs, physical, safety, environmental, and economic factors which are external.
- Life-cycle cost analysis is the basis for management of pavement and having the total cost of the project, including construction at the initial stage, regular maintenance, and important rehabilitation activities over the pavement lifetime.
