摘要：
The effect of long-term skid-resistance performance of asphalt mixtures was studied in this paper. To achieve this objective, three GAC-13C asphalt mixtures including diabase, basalt, and limestone were studied using the model mobile load simulator equipment(MMLS3). Then, grey relational analysis between aggregate characteristics and the long-term skid-resistance performance was conducted. After that, a long-term skid-resistance performance prediction model based on aggregate characteristics was developed. The test results show that with the increase of loading repetitions, the skid-resistance of GAC-13C descended. After a certain amount of loading repetitions, the skid-resistance became stable. A high positive correlation was found between the polished value and the initial value and final value of long-term skid-resistance indexes. The crush value has a significant impact on the attenuation rate. © 2019, Editorial Department of Journal of Tongji University. All right reserved.
