Abstract

The quality of the asphalt mixture was influenced by using the type and arrangement of aggregate, asphalt and, filler. Filler Stone ash, fly ash is commonly used in asphalt mixtures. However, these fillers are hard to find and not cheap. Candlenut shell ash (CSA) is expected to be an alternative. This research was conduct to evaluate the effect of using CSA as filler substitution on Marshall characteristics of the AC-BC mixture. The research method begins with making test samples with variations in asphalt percentage to obtain optimum asphalt content for each percentage of CSA substitution to the weight of filler in the mixture, which is 0%, 10%, and 20%. Research results show that the highest stability value is obtained when using 20% CSA, which is 2,373.06 kg. The increase of the percentage of CSA in the asphalt mixture causes the VIM and flow values to decrease, while the VFA and MQ increase. density and VMA values did not change significantly. The highest durability value was obtained at 20% CSA, which was 101.8%.

Abstract

Efforts to improve the quality of asphalt mixture can be done by modifying the asphalt. Materials that can be used to modify asphalt include plastic waste, waste tires, rubber latex, and gum resin. In this research, the modified material used is gum resin at 4% of the weight of the asphalt in the mixture as a substitute material. This research aims to determine the impact of using gum resin on the asphalt concrete-binder course (AC-BC) mixture on Marshall parameters. The method used is by conducting experiments in the laboratory starting with the search for the optimum asphalt content (OAC) either using gum resin or not as a comparison asphalt mixture. After obtaining the KAO values ​​from the two types of mixtures, the next step is to make samples using 4% gum resin on OAC to be compared with samples of asphalt mixture in OAC without using gum resin.. Research results show that the use of asphalt-modified material in the form of gum resin powder has been able to achieve the value of the Marshall parameter requirements set. A substantial difference in this research is in the stability value, where the asphalt mixture using gum resin is obtained at 2380.48 kg, while the asphalt mixture without gum resin is obtained at 2143.92 kg. The durability value of the mixture using gum resin was obtained at 96.88%, and the durability value of the mixture without gum resin was obtained at 97.02%. It shows that the use of gum resin as a modified asphalt material can produce a mixture of asphalt that is stronger in accepting vehicle wheel loads and can withstand changes in temperature and weather as indicated by the results of a durability value greater than 90%.

AbstractThe ups and downs of the COVID-19 pandemic in Indonesia have caused economic, educational, and social aspects of public lives to experience a decline. Changes in community activity patterns are a warning for the central and regional government to bring public lives back to normal. Such effort can be seen in the government issuing policies regarding preventive measures to suppress the impact of the COVID-19 pandemic. One kind of such policy is the regulation of Domestic Travelers (PPDN). This policy certainly has positive and negative impacts on both the users and providers of transportation services. The purpose of this study is to see the impact of the regulations applied on the characteristics of service users in choosing the mode of transportation. The alternative modes of transportation used in this study are public, private and air transportation. The method used in this study is a quantitative descriptive method by distributing questionnaires to the target samples. The data were then processed and analyzed using a multinomial logit model approach through STATA 13 software to obtain the probability of each mode of transportation. The results show that there were several factors that influence the choice of transportation modes, the amount of income (X1), type of work (X4), gender (X3), cost (X2), travel time (X6) and comfort (X7). The probabilities of the three selected modes of transportation were Ppublic transportation = 56.07%, Pair freight = 34.54 % and Pprivate transport = 6.08%. The results indicate that the more demanding mode of transportation was the land transportation (public transportation).Keywords: Mode of Transportation, COVID-19, Logit Model, PPDN.

Abstract

This study aims to determine the effect of replacing 2% gum resin in asphalt-on-asphalt concrete-binder course (AC-BC) mixtures. The initial step is to examine the physical properties of the asphalt mixture, followed by making samples with several percentages of asphalt to determine the optimum asphalt content (OAC). After OAC was obtained, samples were made again on OAC either without or with 2% gum resin replacement. The OAC obtained for the asphalt mixture without gum resin replacement was 4.75%, while the OAC with 2% gum resin replacement was 4.65%. The stability value of the mixture with 2% gum resin replacement was higher than the mixture without gum resin, namely: 2,276.66 Kg compared to 2,143.92 Kg. Density, void in mineral aggregate (VMA), a void filled by asphalt (VFA), flow, and Marshall quotient values of the two types of mixtures met the required specifications. The results of calculating the durability of the mixture without gum resin replacement were obtained greater than the mixture with 2% gum resin replacement, namely: 93.16% versus 97.03%. This shows that the two types of mixtures can survive and not be damaged when changes in temperature and weather occur. It can be concluded that the use of gum resin as a substitute for asphalt can improve the quality of the asphalt mixture both in receiving repeated traffic loads and in dealing with climate change.

Abstract

Abstract: Endurance of asphalt concrete pavement on traffic load and temperature depends on the type and composition of aggregates, asphalt and filler used. Many attempts have been made to improve the quality of the mixture, such as using modified asphalt. Modified asphalt made by mixing hard asphalt with addition material, such as: plastic, latex and second tires. In this study, the additional material used were plastic polystyrene (PS) as asphalt substitute material and rice husk ash as filler for 50% of the total weight of the filler in AC-WC mixture. Stone ash, cement and fly ash hasbeen commonly used as a filler in asphalt mixture. But, the kind of filler was hard to find and the price were relatively expensive.Rice husk ash which has a specific gravity greater than asphalt, is expected to be one alternative. This study aims to determine impact of plastic substitution into asphalt pen. 60/70 as well as the use of rice husk ash and Portland cement combinations as filler to Marshall characteristics of AC-WC mixture. The early stages of this research is to find the optimum asphalt content (OAC). After OAC obtained thenthe specimens were mixed without and with substitution percentage variation of plastic PS 7%, 9% and 11% to the weight of asphalt. The results showed the use of plastic PS in the AC-WC mixture improve Marshall parameters, especially the value of stability and MQ. Highest MQ and stability value obtained in PS 11% mixture with asphalt content 6,80%, those were  2761.96 kg and 1105.76 kg/mm. No significant changes was found in the density, VMA and VFA value for all substitution percentage variation of PS. Flow value decreasedby the increasing percentage of PS, while the VIM value tended to increase. The durability value of AC-WC mixture with and without PS substitution had met the requirements, those were 90%.Keywords : Asphalt Concrete Wearing Course (AC-WC), Modified Asphalt, Polystyrene(PS)Abstrak: Ketahanan perkerasan beton aspal terhadap beban lalulintas dan temperatur sangat tergantung pada jenis dan komposisi agregat, aspal serta filler yang digunakan.
