Abstract: Moisture susceptibility has been recognized as a major pavement distress. This study examines the resistance to moisture damage of lime-modified asphalt mixtures containing EAF slag. For this study, seventeen (17) mixtures containing 0-4% of lime and 0-100% of slag was generated using Box Behnken Design (BBD) in design expert. The asphalt mixture samples were prepared and the...
Abstract: Since the late 1980s, government agencies have used porous asphalt-treated courses (PATC) as drainage layers under Portland cement concrete and asphalt concrete to prevent premature pavement failure by allowing water to drain from the pavement structure. Although PATC has been used in other applications, its use in airports is relatively limited. Three different types of PATC mixes...
Abstract: Self-healing by induction heating stands as a promising and sus-tainable technology for asphalt pavement maintenance applications. This study involves performing a series of test cycles, encompassing first SCB fracture testing on a waste steel fiber (WSF)-reinforced for an asphalt con-crete for thin surface layers (BBTM) and asphalt concrete for binder layer (ACL), induction heating...
Abstract: In Australia, thin (50-80 mm) asphalt is widely used as the primary type of surfacing for airfield pavements. The function of the asphalt surface is to provide a flexible, waterproof, durable, and skid-resistant wearing layer on top of the pavement structure. During production of airfield asphalt, variable constituents result in variations in the air void content of the mixture....
Abstract: Grouted macadam (GM), composed by a porous asphalt mixture whose air voids are filled with a cementitious grout, is efficiently used as wearing course in semi-flexible pavements subjected to heavy-load traffic and low speed. Since high steering angles, applied by vehicle load at low speed, induce high shear stresses on the surface, this research investigated the raveling resistance...
Abstract: In recent years, the excellent mechanical properties of asphalt modified with graphene nano-platelets (GNPs) have attracted a growing number of researchers investigating their actual performance enhancement in pavements. First, the authors analyzed an original thin layer of graphene-modified asphalt (GMTL) aimed at restoring the binder layer of road pave-ment through laboratory and...
