Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh karet alam siklik terhadap rongga aspal modifikasi. Tahapan peneltian meliputi pembuatan aspal modifikasi dengan menyampur aspal murni dengan karet alam siklik, pengujian persyaratan fisik aspal, pembuatan benda uji dan pengujian marshall. Berdasarkan pengujian sifat fisik aspal diperoleh data bahwa keseluruhan aspal modifikasi memenuhi persyaratan fisik aspal. Setelah pembuatan benda uji, dilakukan pengujian marshall untuk memperoleh rongga aspal meliputi VIM, VMA dan VFA. Nilai VIM pada penambahan 0 phr, 1 phr, 2 phr, 3 phr, dan 4 phr adalah 3,65%, 5,41%, 4,27%, 3,84%, dan 2,88%. Nilai VMA sebesar 15,52%, 17,26%, 16,07%, 15,80%, dan 15,17%. Nilai VFA sebesar 76,48%, 68,72%, 73,54%, 75,76%, dan 81,34%. Diperoleh kesimpulan bahwa karet alam siklik bisa dijadikan sebagai bahan memodifikasi aspal dan berpengaruh terhadap rongga aspal.

This research aimed to determine the effect of cyclic natural rubber (CNR) to cavity of modified bitumen. The steps of the research were mixing the pure bitumen with CNR, testing bitumen physical requirement, making the specimen, and testing the cavity of modified bitumen with marshall method. Testing showed that all the modified bitumen met the physical requirement. After making specimen, marshall method was used to determine the cavity of bitumen, including VIM, VMA, and VFA. VIM in addition of 0 phr, 1 phr, 2 phr, 3 phr, and 4 phr was 3,65%, 5,41%, 4,27%, 3,84%, and 2,88%. The value of VMA was 15.52%, 17.26%, 16.07%, 15.80% and 15.17%. The value of VFA was 76.48%, 68.72%, 73.54%, 75.76% and 81.34%. The conclusion of this study was CNR could be used as material for bitumen modified and had the effect on bitumen cavity.
