| Abstract: | Combined with the engineering practice of highway maintenance, a large number of labora- tory tests has been used to study on the asphalt mastic performance and mixture road performance of Indonesia Buton rock asphalt. Test results show, with the increase in the dosage of rock asphalt, the thermal stability and anti-aging have increased significantly. In addition, dynamic stability, stability, splitting strength and other indicators of asphalt mixture have been improved. |
