THE STIFFNESS MODULUS OF ASPHALT CONCRETE FOR DESIGN LIFE PREDICTION OF PAVEMENT UNDER TROPICAL CONDITION
Stiffness modulus of asphalt mixture is one of key parameters for analytical design of flexible pavement that it is very susceptible against temperature and time loading, meanwhile mostly monographs of flexible pavement design based on the temperature standard of about 25 oC. The objective of this research is to know influence of tropical condition especially in Indonesian temperature and time loading against stiffness modulus value of asphalt concrete mixes and design life. Analysis of Indonesian temperature condition for 10 years and indirect tensile modulus test by using UMATTA ( Universal Material Testing Apparatus) were carried out to determine stiffness modulus of asphalt concrete mixture on optimum asphalt content with temperature variation at 25 oC, 37.5 oC and 50 oC and time loading variation. From analysis results of indirect tensile modulus test program, they were found that the temperature and time loading variation have an influence on stiffness modulus, loading period of elastic condition and design life.
