COST EVALUATION OF ALTERNATIVES TO REHABILITATE ASPHALTIC RURAL ROADS

The debilitating effects of frost and the steady increase in the number and weight of trucks using asphaltic rural roads have contributed to the loss of desirable cross-slopes by creating potholes, rutting, shoving, corrugations, and double crowns. Two general methods are available for local gvernments to correct this deteriorated condition. The traditional method is to level the road by adding either hot-mix or cold-mix asphalt to re-establish the proper cross-slope and add structural depth. Another method is to recycle the existing asphaltic materials and base in place. This practice has resumed because of the dramatic increases in asphalt products that resulted from the worldwide petroleum crisis that started in the 1970s. The cost-effectiveness of both methods combined with the use of different top courses for the wearing surface are analyzed in this paper. Examples of this work that were completed by county personnel will also be analyzed.
