Abstract

We developed an empirical tool to estimate the optimal highway durability in cold regions. In order to test the model, we assembled a data set containing all highway construction and maintenance projects in Arizona and Washington state from 1990 to 2014. The data set includes information on location, time, type (resurfacing, construction or lane widening), pavement material and thickness and total expenditure of these projects. From the data we first estimate how highway maintenance costs and highway duration depend on pavement thickness and traffic loading. We then calibrate the effects of different deicers on highway durability and thus highway maintenance costs. We finally demonstrate how the estimated and calibrated model can be used by planners to make optimal decisions on highway pavement and winter operations in cold regions.
