Temperature Durations at Various Depths in Bituminous Roads

J. W. Galloway

The temperature of a bituminous road layer has a considerable influence on its elastic properties and hence upon its ability to spread wheel loads. Methods are available for measuring the temperature susceptibility of the elastic properties, but hitherto no reliable information was available of temperature distribution in roads throughout a typical English year. Measurements were made of the duration for which the temperatures in the air, and at various depths in two flexible road sections, were within successive ranges of 5C between - 10C and + 50C. Each section had 4 - in of rolled asphalt surfacing and a 10 - in hoggin sub-base; the 10 - in bases were rolled asphalt and lean concrete. The results are presented in several tables and graphs.
