Marshall Stability

Reclaimed Asphalt Pavement of national roads in East Java Province can be used at AC-WC, AC-BC, AC-Base layers, with a percentage of RAP usage of 20-40%, optimum RAP of 20-30%, asphalt’s content in RAP of 3,78-4.63% (Widayanti, 2018). The composition of the addition for 20% RAP which is originated by Taman-Waru with natural aggregates produces Marshall stability of 830.482 kg and melting / flow of 3.8 mm (Handayani, 2007). Therefore, it is necessary to have research of the analysis about the composition of the Reclaimed Asphalt Pavement (RAP) in the amount of 25%, 30%, 35% as the Asphalt Concrete - Wiring Course (AC-WC) layer against the characteristics of the Marshall. The purpose of this research are 1.) To find out the optimum asphalt content (KAO) in a mixture of AC-WC (Asphalt Concrete - Wearing Course) asphalt and 60/70 Asphalt mixture with the usage of RAP material and natural aggregate in accordance with the General Specifications of Bina Marga 2018 2.) Knowing the effect of the usage of RAP material and natural aggregate for the   gradation of asphalt mixture of AC-WC (Asphalt Concrete - Wearing Course) in accordance with the General Specifications of Bina Marga 2018 3.) Knowing the performance of AC-WC asphalt concrete mixture (Asphalt Concrete - Wearing Course) and 60/70 asphalt mixture of RAP material and natural aggregate in terms of Stability and Marshall Quotient values. The research was carried out by the experimental method through laboratory testing. The expected benefit of this research is the discovery for optimizing of the usage recycle materials from road pavement that will be reused during the implementation of road maintenance work and give an alternative of the minimum natural aggregate’s usage. The result of the testing in the laboratory, the mixture of heat asphalt AC-WC with 25% of RAP, had the highest Marshall stability of characteristic for 1309 kg. It’s caused the new materials of the mixture composition has better quality than the mixture of   RAP materials, but the additions of RAP composition for 25%, 30%, 35% still can be used as the alternative substitution of nature aggregate, because those are still the Bina Marga’s specification in 2018 of AC-WC mixture.

ABSTRACTReclaimed Asphalt Pavement (RAP) material as a result of road maintenance by Scrapping-Filling-Overlay method is a waste material which had potential to be recovered as a surface layerof road. The maintenance in highway road of Indonesia used hot mix asphalt in general. But, hot mix asphalt are not environmentally friendly and makes energy wasting because it needs burning process at mixing. Those things are the main causes of this research. This asphalt concrete with RAP with cold mixing is expected to fulfill the requirements of asphalt concrete for heavy traffic. In this research is asphalt content variations at 6,5; 7,0; 7,5; 8,0; and 8,5% to total mixture. The results of this research shows that the highest Marshall stability could not reach minimum value of heavy loaded traffic, that is at emulsion asphalt content 7% only for 711 kg. Besides, the percentage of void in mixture (VIM), void filled with bitumen (VFB) and flow couldn’t fulfill the specification of SNI 8198:2015. With the result that optimum asphalt content cannot be obtained. Result of wheel tracking test could not be obtained too because the specimens collapse during the test.Key words : Emulsion asphalt, Reclaimed Asphalt Pavement, stability, Wheel Tracking MachineABSTRAKMaterial Reclaimed Asphalt Pavement (RAP) hasil dari pemeliharaan dengan metode Scrapping-Filling Overlay merupakan limbah yang berpotensi untuk dimanfaatkan kembali menjadi lapis permukaan. Pada umumnya penanganan jalan di Indonesia menggunakan campuran panas. Namun, campuran panas kurang ramah lingkungan dan tidak hemat energi. Karena membutuhkan proses pembakaran dalam proses pencampuran. Hal ini yang menjadi alasan utama penelitian ini. Beton aspal dengan bahan utama RAP dengan campuran dingin ini diharapkan mampu memenuhi syarat lapisan aspal beton untuk lalu lintas berat. Variasi pada penelitian ini adalah kadar aspal 6,5; 7,0; 7,5; 8,0; dan 8,5% terhadap total campuran. Hasil dari penelitian menunjukan bahwa stabilitas Marshall tertinggi tidak mampu mencapai nilai minimum untuk lalu lintas berat, yaitu pada kadar aspal emulsi 7% hanya sebesar 711 kg. Selain itu prosentase rongga dalam campuran (VIM), rongga terisi aspal (VFB) serta kelelehan tidak memenuhi spesifikasi dari SNI 8198:2015. Sehingga, kadar aspal optimum tidak didapatkan. Hasil dari pengujian alur roda juga tidak didapatkan karena benda uji amblas ketika pengujian dilakukan.Kata kunci : Aspal emulsi, Reclaimed Asphalt Pavement, stabilitas, Wheel Tracking Machine

This study is to assess the suitability of Reclaimed Asphalt Pavement (RAP) as a coarse aggregate substitution for flexible pavement mixture. The RAP in this investigation was taken from roads in Padang, Indonesia. There were three types of flexible pavement chosen to be tested for RAP substitution, i.e. Asphalt Concrete-Wearing Course (AC-WC), Asphalt Concrete-Binder Course (AC-BC), and Hot Rolled Sheet-Wearing Course (HRS-WC). Laboratory studies have been carried out on flexible pavement mixes with RAP material and their performance has been compared with flexible pavement without RAP substitution. Marshall tests were carried out in laboratory as per 2010 specification 6th division from Indonesia Public Work Department standard. The effects of RAP on physical and rheological properties of the final bituminous blend were investigated. The research aims to find out the effect of RAP as coarse aggregate substitution to the flexible pavement characteristics, i.e. Stability, Flow, Marshall Quotient (MQ), Void in Mix (VIM) and Void in Mineral Aggregate (VMA). The percentage of RAP substitution is 35%, 55%, and 60%. From the results of the tests in the laboratory, it was concluded that the AC-WC pavement was more appropriate due to, it has achieved the highest Marshall stability, with VIM, VMA, and VFB were in the standard.

The Impact

Warm mix Asphalt (WMA) could be mixed and used in paving at low temperatures to minimize the consumption of energy and the emissions of greenhouse gas. Recycled Asphalt pavement (RAP) could save Asphaltic cement and aggregate, which could achieve the better effects of recycling. However, both of the two WMA and RAP technologies have some deficiencies. Warm mix Asphalt and Reclaimed Asphalt pavement (WMA-RAP) technique may solve these issues and deficiencies when they are utilized together. This study investigated the implementations of WMA-RAP and its impacts on the performance of the Asphalt mixture. Under the framework of this study, four percentages of RAP (0%, 20%, 30%, and 40%) were added to the hot mix Asphalt (HMA) and WMA containing 4% Sasobit to study the impact of increasing RAP content on Marshall stability and moisture resistance of Asphalt mixtures. In summary, the Marshall stability of HMA and WMA mixtures is higher than the control mixtures. A small decrease in moisture resistance of both (HMA and WMA) containing RAP comparing to control mixtures Asphalt was observed, as shown by reduced the tensile strength ratios (TSR), but it is still much higher than the minimum of 80%.

Blending Process

This paper presents a laboratory study in which the blending process of reclaimed asphalt pavement (RAP) with virgin mixture was analyzed through controlled experiments. One type of screened RAP was blended with virgin (new) coarse aggregate at different percentages. A blended mixture containing 20% of screened RAP was subjected to staged extraction and recovery. The result from this experiment indicated that only a small portion of aged asphalt in RAP actually participated in the remixing process; other portions formed a stiff coating around RAP aggregates, and RAP functionally acted as “composite black rock.” The resulting composite layered structure was desirable to improve the performance of the hot-mix asphalt mixture.
