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.

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.

The Stability

Abstract Inundation due to heavy rain often disturbs traffic flow and porous pavement as a wearing course is one solution to overcome standing water. This asphalt mixture uses an open gradation which is dominated by coarse aggregate with an air cavity content ranging from 20% - 25%. In Indonesia, according to the Indonesian Solid Waste Association (2013), this type of plastic waste ranks second with 5.4 million tons per year and is ranked second in the world as a producer of marine plastic waste after China. This research tries to use plastic waste as an added material in the porous asphalt mixture where the gradation of porous asphalt refers to REAM Specifications, 2008. The type of plastic used is Low Density Polyethilene (LDPE). The levels of plastic waste used were 0%, 2%, 4%, 6%, 8% of the total weight of the mixture. Marshall and Cantabro characteristics tests were conducted to evaluate the resulting mixture. The results of this study indicate that the stability value meets the REAM specifications, namely 350 - 800 kg. Marshall test results with the use of LDPE plastic waste as an additive to the test object meet the characteristics of Marshall except for Marshall Quotient (MQ) and voids filled with bitumen (VFB).

The Relationship

Based on the Bailey method for aggregate grading design and evaluation, the parameter "reserved voidage" is used in porous asphalt method design. The paper studies the relationship between the three parameters (reserved voidage, blend by volume of the coarse aggregates totaling 100.0% and chosen unit weight of coarse aggregate) and the pavement performances, such as deformation, resistance at high temperature, low-temperature anti-cracking and moisture susceptibility of porous asphalt mixture. The test results indicate that the porous asphalt mixture designed by the modified Bailey Method is of the characteristics of air void easier to control and superior performance.
