Development of Asphalt Pavement Temperature Profile Model for Tropical Climate Conditions in the Eastern Bali Region, Indonesia

抄録

The temperature in the asphalt pavement layer varies which is influenced by climatic environment factors, such as air temperature, humidity, solar radiation, wind speed and the reflection of the pavement surface. Indonesia has a specific tropical climate characteristics and a temperature observation station was placed on the national road segment of Singaraja - Amlapura (Km 81 + 100 - Km 95 + 00) which is located in Karangasem regency in the eastern of Bali Region, Indonesia, to monitor air temperature, humidity and temperature of asphalt pavements at depths of 00 mm, 20 mm and 70 mm. It is obtained that, there was a positive linear relationship between the air temperature and asphalt pavement temperature. Based on the statistical analysis and test models, it can be concluded that both variables have a high correlation, and most of the asphalt pavement temperature variation can be explained by those two independent variables.
