Analysis on Economic Benefit of Pavement Layer Based on Net Present Value Method

This paper explains the method and theory of cost net present value, and uses this method to analyses the economic benefits on several pavement inter layer (emulsified asphalt seal coat, rubber modified asphalt and stress absorbing layer of fiberglass polyester paving mat) during the 15-year period, results showed that rubber modified asphalt and stress absorbing layer of fiberglass polyester paving mat is superior to emulsified asphalt seal coat.
