Document Summary
Usually carried out as part of feasibility study. Pavement design is governed by a number of factors, as outlined below: The design life or performance period refers to the period of time for which the initially designed pavement structure will last before any rehabilitation is needed. It is to be noted that the design life or performance period can be dependent, to a very large extent, on the type and level of maintenance provided over the design life. The analysis period is the number of years that any design strategy must cover; the aashto guidelines in this regard are given in table 1. Table 1 analysis period for different highway conditions. The term reliability" stands for the probability" that any particular type of distress (or combination of distress manifestations) will remain below or within the permissible level during the design life.
