Title: ENGINEERING ANALYSIS OF THE ECONOMICS OF PREDICTED PAVEMENT LIFE (WITH DISCUSSION AND CLOSURE)

Availability: Find a library where document is available Abstract: The problem of deteriorating infrastructure--including highways and the cost of proper maintenance--is a major point of debate for policy makers. With continued tight budgets and increasing deficits, policy makers are looking harder at the costs of building and maintaining a viable highway network. Economists and engineers sometimes disagree on pavement maintenance, design, and construction costs. For example, K. Small, C. Winston, and C. Evans, authors of "Road Work" (1989), have proposed that costs of highway maintenance could be reduced by billions of dollars by increasing the thickness of the nation's highways and by imposing a national system of weight-distance taxation. The authors of "Road Work" base their assertion that highway engineers underdesigned the nation's highways on a re-analysis of the AASHO Road Test data using a survival regression analysis. An analysis of the "Road Work" study concluded that the results are similar to those of the original AASHO Road Test when additional traffic is considered. "Road Work" may have used questionable assumptions regarding pavement service life, the role of thickness in pavement performance, and predicted traffic growth. As a result, the estimated savings in the maintenance of the nation's highways seem to be vastly overstated. The analysis concluded that current pavement management economics and thickness design, although not perfect, are reasonable.
