Pavement Performance from Historical Data
Historical performance data in terms of useful pavement life and surface condition were related to loading conditions, paving materials, and subgrade strength. The computer program 'Statistical Analysis System' (SAS) was used to explore the relationships which existed within the data. Pavement performance was evaluated in either one of two ways. For roadways which had been overlaid, the performance characteristic was taken as the useful life of the roadway between construction and overlay. For roadways which had not been overlaid since construction, the pavement surface condition parameters of roughness, cracking, and a combined rating were used to evaluate pavement performance. Some of the results of this research effort were as follows. The deterioration of pavements in North Dakota is more directly related to the age of the pavement than to the daily axle loadings or soil subgrade strength. This may be related to another finding that actual pavement life usually exceeded design life. An interesting outcome of the research which was not totally explainable was that pavements in the eastern Highway Department districts had considerably less cracking than those in the western part of the state.
