Temperature is one of the important factors that affect the stiffness of bituminous layers and cause deterioration of the pavement. In the tropics, information regarding temperature variation and its distribution within a bituminous pavement is scarce. To provide data on this important aspect of bituminous pavement design and performance, a test set-up consisting of 150 mm water bound macadam sub base, 62 mm bituminous binder course, and 25 mm wearing course (sheet asphalt) was used. The test site was at latitude 10 deg 50' north, and longitude 78 deg 40' east at an approximate elevation of 75 M above mean sea-level. Thermocouples were installed at depths of 0, 12, 25, 50, 87, 162 and 237 mm, and a digital multimeter was used to record the temperatures. The temperatures at the surface and at depths 25, 50 and 75 mm gave significant correlation with the air temperature at the test site. As a result of this study, an empirical method of estimating the pavement temperatures at different depths of the bituminous layers is suggested. /TRRL/
