Temperature sensitivity effect in asphalt modification with natural rubber sir20

Abstract

The use of asphalt material is needed so that surface layer could be water-resistant. Asphalt material also improves tensile stress which means enhancing support capacity for traffic load. Asphalt modification can be done by adding certain materials, such as natural rubber, to improve asphalt performance. Experimental methods were taken in this study. Asphalt tests which carried out are specific gravity, softening point and penetration with natural rubber variation 2%, 4%, 6%, 7%, 8%, 9%, 11% and 13%. Results were shown that the higher addition of natural rubber SIR20, asphalt more hardened and more insensitive to changes in temperature. This hardness characteristic of asphalt could be the initial parameter for making asphalt mixtures that more resistant to rutting and permanent deformation.

Sensitivitas Aspal Modifikasi Terhadap Temperatur

“…Setiap bahan tambah memiliki karakteristik yang berbeda-beda sehingga sensitivitas aspal modifikasi yang dihasilkan akan beragam. Beberapa penelitian skala laboratorium yang dilakukan program studi Magister Rekayasa Infrastruktur Politeknik Negeri Bandung menunjukkan bahwa aspal modifikasi dengan polimer memiliki nilai titik lembek dan penetrasi yang berbeda [2][3][4][5] [6]. Aspal modifikasi dengan karet SIR20 merupakan modifikasi aspal dengan polimer jenis elastomer.…”

“…Berbagai penelitian telah dilakukan pada karet alam berdasarkan aspek kompatibilitas dan interaksi yang berbeda antara polimer dan aspal yang bertujuan untuk meningkatkan kinerja material yang dimodifikasi. Dari tinjauan tersebut, karet alam yang digunakan dalam bentuk lateks pekat, Ribbed Smoked Sheet (RSS) dan Liquid Natural Rubber (LNR) menunjukkan harapan dalam memperbaiki campuran aspal [6].…”

“…Hal tersebut menunjukkan sifat aspal yang semakin tidak sensitif dan semakin kuat terhadap temperatur. Referensi [6] berpendapat jika suatu aspal semakin tidak sensitif terhadap temperatur, maka campuran aspal ini semakin kuat terhadap deformasi permanen akibat penambahan beban.…”

“…Adhesive between layers of adhesion on paved road pavement is a heterogeneous composite material [17][18][19][20]. Road damage is not only caused by the incompatibility of adhesive materials, instability of the road sub-layer, temperature IOP Publishing doi:10.1088/1755-1315/1358/1/012002 2 factors, traffic load, and density [21][22]. Road damage is also caused by asphalt pavement failure, resulting in cracks that then become holes [23][24][25].…”
