Abstract

Abstract Penetration Index is one of the parameters of asphalt’s temperature susceptibility. The lower the Penetration Index, the lower the bitumen’s temperature susceptibility. One solution to improve the level of asphalt’s temperature susceptibility is by adding pure Asbuton to pen 60/70 petroleum asphalt. The proportion of pure Asbuton added to the pen 60/70 petroleum asphalt varies from 0% to 100%. The value of Penetration Index is determined by the Pfeiffer and Van Doormall equations, which is affected by penetration and softening point of asphalt. The analysis performed shows 2 different zones. In the first zone, with pure asbuton content of 0%-30%, the Penetration Index did not change significantly, while in the second zone there was a significant changes in the Penetration Index values. It is found that the addition of pure asbuton of 2%-30% will result in larger Penetration Index values, meaning that the level of asphalt’s temperature susceptibility is better. Keywords: Penetration Index, softening point, petroleum asphalt, Asbuton  Abstrak Indeks Penetrasi adalah salah satu parameter pengukur kepekaan aspal terhadap temperatur. Makin rendah nilai Indeks Penetrasi, makin rendah tingkat ketahanan aspal terhadap perubahan temperatur. Salah satu cara yang dapat dilakukan untuk memperbaiki tingkat kepekaan aspal terhadap perubahan temperatur adalah dengan memodifikasi aspal minyak penetrasi 60/70 dengan asbuton murni. Persentase kadar asbuton murni yang ditambahkan ke dalam aspal minyak penetrasi 60/70 bervariasi mulai dari 0% sampai 100%. Nilai PI ditentukan berdasarkan Persamaan Pfeiffer dan Van Doormall, yang merupakan hubungan antara nilai penetrasi dan titik lembek aspal. Hasil analisis menghasilkan 2 zona yang berbeda. Pada zona pertama, untuk kadar asbuton murni 0%-30%, nilai Indeks Penetrasi tidak berubah secara signifikan. Sedangkan pada zona kedua terjadi perubahan yang signifikan pada nilai Indeks Penetrasi. Penambahan asbuton murni sebesar 2%-30% menghasilkan nilai PI yang lebih besar, artinya tingkat ketahanan aspal terhadap perubahan temperatur semakin baik. Kata-kata kunci: indeks penetrasi, titik lembek, aspal minyak, Asbuton

Abstract

Abstract One way to reduce damage of the pavement structure is to improve the quality of asphalt used. In an effort to improve the quality of the asphalt, additives are added, such as polymers. This study aims to determine the basic characteristics of Low Density Polyethylene Plastic modified asphalt, which includes penetration, softening point, flash and fire point, specific gravity, ductility, viscosity. In addition, it will be determined the maximum content of Low Density Polyethylene Plastic which produces modified asphalt that meets the standards of the Directorate General of Highways. The results of this study show that modified asphalt with Low Density Polyethylene Plastic can increase the asphalt softening point and reduce penetration value, flash and fire point, specific gravity, ductility, and viscosity of asphalt. The maximum LDPE Plastic content that can produce modified asphalt that meets specifications of the Directorate General of Highways is 5%. Keywords: plastic, asphalt quality, additives, basic characteristics of asphalt, modified asphalt  Abstrak Salah satu cara untuk mengurangi kerusakan struktur perkerasan jalan adalah dengan meningkatkan mutu aspal yang digunakan.

Abstract

Ravelling is road damage that occurs when the bond between aggregate and asphalt has been lost. One of the factors of ravelling damage is caused by the decreasing value of cohesion and adhesion. Therefore, the material factor becomes one of the parameters in increasing the value of cohesion and adhesion to asphalt. To improve material quality as well as an effort to reduce environmental pollution, polypropylene (PP) plastic waste is used in asphalt concrete wearing course mixtures. This study aims to determine the effect of adding polypropylene (PP) plastic waste to Marshall characteristics and revelling resistance seen from the VIM value and abrasion value with variations in polypropylene (PP) waste content as much as 0%, 2%, 4%, and 6% of the weight of the asphalt. Marshall test results show that the values ​​of stability, VMA, and MQ tend to increase, while the values ​​of flow, VIM and VFA tend to decrease with the increase in the percentage of polypropylene (PP) plastic waste content in the asphalt. As for the reMults of the abrasion value with a simple ravelling modification tool, it shows that the higher the percentage of polypropylene (PP) plastic waste in the asphalt, the smaller the VIM and abrasion value. It can be concluded that the addition of polypropylene (PP) plastic waste can improve the performance of the mixture against ravelling resistance seen from the VIM value on the Marshall parameter and the abrasion value of the ravelling test.
