Abstract

In this study, the effect of mastics with four different mineral fillers (limestone, granodiorite, dolomite and rhyolite) on the mechanical performances of porous asphalt (PA) mixtures was investigated. X-ray computer tomography (X-ray CT) scanning and digital image processing (DIP) techniques were applied to detect and reconstruct the microstructure of PA specimens. Finite element (FE) simulations were conducted to simulate indirect tensile tests. The results show that the mastics with different fillers have significant influence on the mechanical performances of PAmixtures.The PAmixture with limestone exhibits the least load-bearing capacity while the specimen with granodiorite exhibits the highest values. Although the distribution and the magnitude of the creep strain in the different mastic are similar, the locations of the maximum creep strain are not the same. Further investigations should be carried out to facilitate the improvement of the pavement design process.
