Abstract

Abstract Material constraints and increasing demand for road construction materials have resulted in high construction costs and road rehabilitation, so alternative materials are needed, such as recycled asphalt and potential waste utilization, such as steel slags. This study is a literature study, with the aim of evaluating and controlling the performance of asphalt mixtures using Reclaimed Asphalt Pavement and steel slag, as a substitute for aggregate. The Reclaimed Asphalt Pavement material generally has aging which causes an increase in stiffness during the structural life and reduced adhesion to asphalt. This can be prevented by steel slag material, which has a rough surface and texture, so as to prevent cracks due to internal friction of the mixture. The overall use of Reclaimed Asphalt Pavement materials and steel slag can improve mixture performance and resistance to fatigue. Keywords: asphalt mixture, reclaimed asphalt pavement, steel slag, flexible pavement  Abstrak Keterbatasan material dan meningkatnya permintaan material konstruksi jalan menyebabkan tingginya biaya pembangunan maupun rehabilitas jalan, sehingga diperlukan material alternatif, seperti daur ulang aspal dan pemanfaatan potensi limbah, seperti slag baja. Penelitian ini merupakan suatu kajian literatur, dengan tujuan melakukan evaluasi dan pengendalian kinerja campuran beraspal yang menggunakan Reclaimed Pavement Asphalt (RAP) dan slag baja sebagai bahan pengganti agregat. Material RAP umumnya telah mengalami penuaan yang menyebabkan peningkatan kekakuan selama umur struktur dan sifat adhesi terhadap aspal berkurang. Hal ini dapat dicegah oleh material slag baja, yang memiliki permukaan dan tekstur yang kasar, sehingga dapat mencegah terjadinya retak akibat gesekan internal campuran. Penggunaaan material RAP dan slag baja secara keseluruhan dapat meningkatkan kinerja campuran dan ketahanan terhadap kelelahan. Kata-kata kunci: campuran beraspal, reclaimed pavement asphalt, slag baja, perkerasan lentur

Abstract

The limitations of road construction materials require alternative materials such as asphalt recycling and utilization of waste potential such as steel slag for aggregate substitutes. In this study, there were tests for slag characteristics and reclaimed asphalt pavement (RAP) then continued with a marshall test to determine the optimum asphalt content (OAC). The nine mixtures planned in this study consist of 10-30% Slag combined with 10-30% RAP with Reclamite as a rejuvenating material. Using a combination of RAP, there is a decrease in the mixing and compaction temperature of 20°C compared to the conventional hot mix. Test results on hot mix asphalt using a combination of RAP and slag generate an increase of 10-30% each using a combined gradation and volume correction. Test result in heat asphalt mixture by using RAP and slag combination with additional of 10-30% each using correction of volume and combined gradation. For the hot mix asphalt with RAP10 and SLAG 10-30 (HMAR10S10-30), the OAC value is 5.83%, 5.95%, and 5.38%, and for the hot mix asphalt with RAP20 and SLAG 10-30 (HMAR20S10- 30), the OAC value obtained is 5.90%, 5.60%, and 5.95%, and for the hot mix asphalt with RAP30 and SLAG 10-30 (HMAR30S10-30), the OAC value is 5.55%, 5.60 %, and 5.33%.

Abstract

Porous asphalt is a mixture of asphalt with low levels of fine aggregate with the aim of providing a large air cavity, so that high permeability can drain surface water into the soil but has low stability. One of the value effects of stability is the aggregate characteristics, where Banten province has quite a lot of aggregate availability, this is beneficial in reducing the cost of building and rehabilitating roads and overcoming the limitations of road construction materials. This study used a University of New Hampshire Stormwater Center (UNHSC) gradation with three types of porous asphalt mixtures with local aggregates, namely Lebak, Serang, and Merak with variations in asphalt content of 4.5%, 5.0%, 5.5%, 6, 0%, and 6.5%. Based on the results of testing the characteristics of the porous asphalt mixture material which includes aggregate, filler and asphalt meet the specifications of Bina Marga 2018, then from the Marshall test, the Optimal Asphalt Content was obtained by 5.5% for the three types of porous asphalt mixtures where all parameters meet the AAPA requirements. While the highest stability parameters were porous asphalt mixtures using Merak aggregate with low permeability coefficient values for the three porous asphalt mixtures. Keywords: porous asphalt, local aggregate, Asphalt Content, marshall, permeability.

Abstract

Abstract The pavement surface layer is a layer that directly interacts with traffic loads and the environment. Water-logging on the road surface causes the loss of the bond between asphalt and aggregate. The purpose of this study was to determine the effect of rainwater on the characteristics of the AC-WC surface layer using Starbit E-55 polymer asphalt. The immersion of specimens was carried out in 2 conditions, namely in fresh water or in rain water, with a duration of 24 hours and 48 hours. The results obtained indicate that there is a decrease in stability more rapidly in rainwater immersion than in freshwater immersion. Marshall Quotient was increased for immersion with a duration of 24 hours and 48 hours. In addition, an increase in the values of flow, voids in the mixture, and voids in the aggregate were obtained. Keywords: pavement; surface layer; waterlogging; traffic load; polymer asphalt.  Abstrak Lapis permukaan perkerasan jalan merupakan lapisan yang langsung berinteraksi dengan beban lalu lintas dan lingkungan.
