Development of a model to predict pavement temperature for Alkufrah region in Libya

Abstract

The structural capacity of the hot mix asphalt concrete layers depends on many factors including its temperature. Moreover, temperature can be a major contributor to several types of distress. This paper presents the research undertaken to develop models to predict high and low asphalt pavement temperatures in Alkufah region, which is located on the southern east of Libya at latitude (24°17'N) in the desert of Libya. A pavement monitoring station was set-up at the Alkufrah airport to monitor air, pavement temperatures in different depth, wind speed and solar radiation. Data were collected for 365 days. Daily minimum and maximum temperatures were recorded. A regression analysis was used to develop the minimum and maximum pavement temperature models, using airtemperature, wind speed and solar radiation.
