Quantification of the Effect of Maintenance Activities on Texas Road Network

16. Abstract Pavement structures are designed for a finite life, usually referred to as performance period. This performance period is typically between 20 to 25 years for flexible pavements and between 25 and 40 years for rigid pavements. After this period, the pavement is predicted to reach a terminal level in terms of several preset criteria. This performance period can be reached by designing a structure that will withstand the effects of traffic and the environment through the design period or by planning a series of maintenance and rehabilitation activities that will keep the structure above the present terminal levels until the end of the design life is reached.
