Abstract
There are some factors that cause deformation on the runway, such as the pressure of repeated loads caused by large queues of aircraft. The aggregate available in nature has begun to decrease in amount caused considering that infrastructure development in Indonesia continues to increase. Therefore, new material innovations are needed to overcome this, such as the use of flyash as an artificial aggregate of geopolymers in concrete asphalt mixtures. This research was carried out in some tests including Marshall testing which intended to determine the characteristics of artificial aggregate pavement mixtures, using open gradations with specification BBA. Then testing the resistance to deformation (Creep) on the artificial gradation aggregate pavement mixture using the UTM30 Dynapave. Based on the characteristics of the Marshall test the optimum bitumen content value was obtained open gradations has OBC value of 6.1%. Results of Creep test obtained strain value is 7874,195 microstrain and stiffness value is 13,297 MPa with repetition of 3600 times. It can be concluded that the pavement mixture with open graded artificial aggregate (BBA) has the ability to resist deformation.
