Abstract:The objectives of this study were to analyze the before and after crash history and speeds on routes which have been resurfaced , inspect resurfacing projects, make recommendations to improve the resurfacing process, and determine improvements which could be made in conjunction with the resurfacing project to improve the overall safety of the roadway.
An analysis of the before and after crash data did not show a reduction in total crashes after resurfacing. There was a reduction in crashes which occurred on a wet pavement. A comparison of speeds before and after resurfacing did not find a major change in travel speeds. Considering all locations, there was an average increase in speeds after resurfacing of less than one mph.
Discussion with state inspectors and contractors found agreement of areas which could be changed to improve the resurfacing process. Most of the comments dealt with preparation of the road prior to paving, methods to place the shoulder, and the paving operation.
