TitleDevelopment of Model Reflecting the Relation Between Air Ambient Temperature and Asphalt Layers Temperature in Gaza Strip
Title in Arabicتطوير نموذج للعلاقة بين درجة حرارة الهواء المحيط ودرجة حرارة طبقات الاسفلت في قطاع غزة
Abstract

Temperature is one of the most important factors affecting the design and performance of pavement. Temperature variations within the asphalt pavement structure contribute in many different ways to distress and possible failure of that structure. The structural performance of pavements is highly dependent on temperatures to which these pavements are exposed. For a successful pavement design, it is vital to know the range of temperatures over which a pavement will be subjected and it is necessary to determine the distribution of temperatures through the pavement asphalt concrete layers. In this study, the distribution of pavement temperatures at surface and at three depths (2cm, 5.5cm, 7cm) below the pavement surface is determined using the temperature data instrument. Data were analyzed for daily and seasonal variations. Surface temperature was found less than the temperatures in all three depths mentioned above which exist below asphalt surface, especially at hot hours of high ambient. It is clear that the maximum temperature of asphalt pavement occurred at noon time in summer and the minimum temperature occurred at dawn time in winter. The thermal pattern behavior of air ambient temperature and asphalt pavement layers during whole day was in two ways, it started in upward behavior from morning to the noon and reflect to downward behavior from noon to the dawn. Using correlation and regression method. A relationship for determining the pavement temperature at different asphalt pavement depths (2 cm, 5.5 cm and 7cm) and air temperatures was suggested, taking into account the behavior of temperatures in two different manners.
