Abstract A problem that may occur in road pavements that are relatively impermeable to water is the runoff of water, because water cannot seep to the bottom of the pavement, so it can be drained into a drainage system. To overcome this problem, a porous asphalt mixture can be used. In this study the use of concrete waste was tried to replace the coarse aggregate used to make porous asphalt mixtures. For this reason, experiments are carried out in the laboratory, by making some specimens, which are then subject to Marshall testing. The coarse aggregate used to make the mixture is replaced by concrete waste, with a proportion of 25%, 50%, 75%, and 100%. The results of this study indicate that concrete waste changes the Marshall parameters of a porous asphalt mixture. Keywords: porous asphalt mixture; Marshall testing; concrete waste; Marshall parameter.  Abstrak Suatu permasalahan yang mungkin terjadi pada perkerasan jalan yang relatif kedap air adalah adanya limpasan air, karena air tidak dapat meresap hingga ke bawah perkerasan, untuk dapat dialirkan ke suatu sistem drainase. Untuk mengatasi masalah tersebut, dapat digunakan campuran beraspal berpori. Pada studi ini dicoba peng-gunaan limbah beton untuk mengganti agregat kasar yang digunakan untuk membuat campuran beraspal berpori. Untuk itu dilakukan percobaan di laboratorium, dengan membuat benda-benda uji, yang selanjutnya dilakukan pengujian Marshall. Agregat kasar yang digunakan untuk membuat campuran diganti dengan limbah beton, dengan proporsi sebesar 25%, 50%, 75%, dan 100%. Hasil penelitian ini menunjukkan bahwa limbah beton mengubah parameter Marshall campuran beraspal berpori. Kata-kata kunci: campuran beraspal berpori; pengujian Marshall; limbah beton; parameter Marshall.

Steel slag is a byproduct, making up a portion of 15-20% of iron output. Most of them are deposited in slag storing yards and thus results in many serious environment problems in China. This paper aims to explore the feasibility of utilizing steel slag as aggregates in porous asphalt mixtures. Open-graded friction course (OGFC), a permeable and porous asphalt mixture, was evolved in this paper. Residual stability ratio test, tensile strength ratio test, seepage test and rutting test got used in the research. Results showed that OGFC with steel slag as coarse aggregate had good performances.

Porous asphalt mixture is one of the alternative solutions to increase pervious surface area due to urbanization. The uniqueness of porous asphalt surface textures and internal structures allows the mixture to become a temporary storm-water retention and capable to channel excessive storm water. However, one of the major problems that affect the performance of porous asphalt mixtures is the clogging. Therefore, this study aims to determine the effect of clogging towards the permeability of porous asphalt. A total of 30 gyratory compacted samples were fabricated according to aggregate gradation recommended by Malaysia Public Works Department. The clogging materials were collected from two different location, residential area and major highway. The composition and characteristics of the clogging materials were investigated using Plastic Limit, Liquid Limit and Scanning Electron Microscope (SEM). The permeability test was conducted to investigate the permeability rate of the compacted samples based on different clogging material types, clogging concentrations and clogging cycles. In addition, the compacted samples were scanned using X-ray Computed Tomography to obtain the air voids distribution throughout the samples for comparison. It was found that higher concentration of clogging materials and clogging cycles reduced the rate of permeability. Clogging material collected from residential area has higher tendency to clog the void spaces compared to the one obtained from highway.

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.

The objectives of this paper are to characterize the mechanical properties of porous asphalt pavement mixtures containing RAP and a WMA additive using Super pave gyratory compactor and dynamic modulus testing. Four types of asphalt mixtures were evaluated in this study. This study evaluated compaction energy index, permeability, indirect tensile strength, and dynamic modulus for all types of porous asphalt mixtures. All of the asphalt mixtures meet the typical minimum coefficient of permeability in this study. In addition, only a slight decrease in was found when WMA additive was added to the porous asphalt mixture containing RAP. For indirect tensile strength testing, WMA containing RAP was found to have the highest tensile strength among all of the mixtures tested.

The morphological properties of coarse aggregates, such as shape, angularity, and surface texture, have a great influence on the mechanical performance of asphalt mixtures. This study aims to investigate the effect of coarse aggregate morphological properties on the high-temperature performance of asphalt mixtures. A modified Los Angeles (LA) abrasion test was employed to produce aggregates with various morphological properties by applying abrasion cycles of 0, 200, 400, 600, 800, 1000, and 1200 on crushed angular aggregates. Based on a laboratory-developed Morphology Analysis System for Coarse Aggregates (MASCA), the morphological properties of the coarse aggregate particles were quantified using the index of fractal dimension. The high-temperature performances of the dense-graded asphalt mixture (AC-16), gap-graded stone asphalt mixture (SAC-16), and stone mastic asphalt (SMA-16) mixtures containing aggregates with different fractal dimensions were evaluated through the dynamic stability (DS) test and the penetration shear test in laboratory. Good linear correlations between the fractal dimension and high-temperature indexes were obtained for all three types of mixtures. Moreover, the results also indicated that higher coarse aggregate angularity leads to stronger high-temperature shear resistance of asphalt mixtures.
