Defects in the pavement decrease the value of the pavement in different propositions. For example, a raveling defect does not decrease the value of the pavement as much as a strength defect. As there are in the pavement system. Determine value loss due to defects. Determine Decay rates and interdependencies to other defects.
Defects can decay at constant rate of change or can change exponentially.
They may be interdependent upon other defects. For example, cracks are made worst by raveling where strength is made worse by raveling. This step and all remaining steps need to be calculated on a computer as they involve many calculations. For example, each segment of the road will have multiple defects and multiple remedies cover multiple years requiring millions of calculations per road segment. Determine optimum effectiveness remedies life and correlate each remedy with defects in a matrix expressed in a percentage of effectiveness.
