“…Abrasion Loss (AL), or the wear resistance of the mixtures, is considered the critical feature for asphalt mixes with high void contents [68]. In this case, it was determined by the Cantabro test, which is widely used to assess the abrasion or raveling resistance of these mixtures and has been demonstrated to present the best correlation with the performance and durability of the porous asphalt [69]. In this test, defined in EN 12697-17 [65], each sample is subjected to 300 revolutions in the Los Angeles drum, without steel spheres (Figure 5a).…”

Electric arc furnace slag (EAFS) and ladle furnace slag (LFS) are by-products of the electric steelmaking sector with suitable properties for use in bituminous mixtures as both coarse and fine aggregates, respectively. In this research, the production of a porous asphalt mixture with an aggregate skeleton consisting exclusively of electric steelmaking slags (using neither natural aggregates nor fillers) is explored. The test program examines the asphalt mixtures in terms of their mechanical performance (abrasion loss and indirect tensile strength), durability (cold abrasion loss, aging, and long-term behavior), water sensitivity, skid and rutting resistance, and permeability. The results of the slag-mixes are compared with a standard mix, manufactured with siliceous aggregates and cement as filler. The porous mixes manufactured with the slags provided similar results to the conventional standard mixtures. Some issues were noted in relation to compaction difficulties and the higher void contents of the slag mixtures, which reduced their resistance to raveling. Other features linked to permeability and skid resistance were largely improved, suggesting that these mixtures are especially suitable for permeable pavements in rainy regions. In conclusion, a porous asphalt mixture was produced with 100% slag aggregates that met current standards for long-lasting and environmentally friendly mixtures.

“…Alvarez et al evaluated the suitability of the Cantabro loss test, the Hamburg wheel-tracking test and the Overlay test to be used for the assessment of OGFC durability and recommended the adoption of the Cantabro loss test for such purpose. This test can be used to optimise the binder content and other volumetric parameters to enhance the durability of OGFC (Alvarez et al 2010). To restore the functionality of OGFC, de-clogging operations such as backwash have been used (Suresha et al 2010).…”

Open-graded friction course (OGFC) is often believed to have no contribution to the structural capacity of flexible pavement. In this study, five types of OGFC mixtures were prepared and tested for rutting potentials, and three of them were tested for dynamic moduli, which were further used to analyse pavement's response and performance based on the procedures in the mechanistic -empirical pavement design guide (MEPDG). It was found that the tensile strain at the bottom of asphalt concrete layers and the compressive strain at the top of sub-grade layer are sensitive to the availability of OGFC, regardless of mixture type. The fatigue and permanent deformation damages of a flexible pavement can be effectively reduced after adding the OGFC layer, due to the alteration of loading frequency, thermal gradient and modulus ratio. Trial designs using MEPDG software in two different climates verify the above observations.

“…Therefore, many researches were developed in this area. It was proposed that the Contabro loss test can be used to evaluate the raveling property of materials in the design process of PA mixture [3][4] . The steel wool was added to the PA mixture to enhance the raveling resistance.…”

Porous asphalt (PA) pavement with large air voids tends to produce raveling phenomenon because of the properties of adhesive material and the impact of application environment. The method of preparation of PA mixture which has high resistance of raveling is optimizing each indicator. The indicators can be obtained from the raveling test of PA mixture considering adding HVA, asphalt binder and external mixing agent to the PA mixture. It is more scientific for PA mixture with small nominal max aggregate size in the upper layer of double layer PA pavement to use plate type abrasion test method to evaluate its resistance of raveling.
