The primary objective of this research was to develop and document the basic methodology required to provide accurate thermal simulations of highway structures. A secondary objective was to use the simulation to perform parametric studies. In order to verify the simulation, an experimental program to measure thermal response of two bridge decks and the adjacent roadway as well as the local micrometeorological parameters was undertaken. Data obtained indicate that the asphalt overlaid deck surface is generally considerably warmer than either the concrete deck (9F) or the adjacent roadway (7F). The asphalt overlaid deck is subject to fewer freeze-thaw cycles than the concrete deck (31%). The concrete deck surface is colder than the adjacent roadway surface (2F).
