... This forecasting sometimes is undertaken pnm~rily on a statistical basis, with simple correlations made between the condition of the building materials or element and the parameters, such as temperature or numbers of loadings, that are presumed from theory to contribute to wear and aging. Sometimes a more elaborate mathematical model of the wear or aging process is constructed to provide the basis for data collection and analysis, but the result will still depend on statistical relationships among observable variables.

... At the same time, work by development economists at the World Bank and elsewhere began to demonstrate convincingly the direct contribution that pavement conditions have on vehicle operating costs and, in tum, on economic efficiency of a region's transportation system. These forces combined to motivate research and development efforts that led to establishment of practical pavement ~nanagement systems, which, after two decades, now are used routinely by many state transportation agencies to monitor highway facilities, to assure maintenance effectiveness, and to schedule rehabilitation and replacement of pavements (Hudson, et al., 1979~.
