高达10%返现 Jul 23, 2021 Both traditional and rheological tests on modified and control asphalt binders were performed. The traditional tests included penetration, softening point, flash and fire points, and ductility. The rheological tests, on the other hand, included rotational viscometer (RV) and Dynamic Shear Rheometer (DSR) tests.

Recent studies have shown that fibers improve the performance of porous asphalt mixtures. In this study, the influence of four different fibers, (a) regular aramid fiber (RegAR), (b) aramid fiber with latex coating (ARLat), (c) aramid fiber with polyurethane coating (ARPoly), (d) aramid fiber of length 12 mm (AR12) was evaluated on abrasion resistance and toughness of the mixtures.

Aug 29, 2017 Water permeability is an important property for porous asphalt mixtures. Previous numerical modeling showed that the permeability of the porous asphalt mixtures varies in different directions and a single permeability cannot accurately evaluate the mixture’s directional permeability. To investigate the direction-dependent water permeability of the porous asphalt

Dec 04, 2021 High viscosity asphalt (HVA) has been a great success as a drainage pavement material. However, the larger porosity of drainage asphalt mixtures weakens the cohesion and adhesion and leads to premature rutting, water damage, spalling and cracking. The purpose of this study was to investigate the rheological properties of HVA prepared using different high
