PENGARUH PENAMBAHAN ‘LIMBAH KARET BAN LUAR’ TERHADAP KARAKTERISTIK MARSHALL PADA LAPIS TIPIS ASPAL PASIR (LATASIR) KELAS B

Abstract

Asphalt mixture Latasir called HRSS (Hot Rolled Sand Sheet). Proper aggregate gradation,
asphalt latasir distinct class A and class B. A known class Latasir HRSS-A with a nominal minimum
thickness of 1.5 cm. As a class known as HRSS Latasir B-B with a nominal minimum thickness of
2 cm. Latasir intended for asphalt road with light traffic, especially in areas where coarse aggregate
is not available. The use of “rubber tire waste” as asphalt additives latasir is expected to reduce the
use of asphalt and benefits, including increases due to the braking surface traction and reduces tire
noise due to friction with the floor surface. The addition of “waste tire rubber” mixing the asphalt
made with a variety B latasir rubber content of 1%, 2%, 3%, 4% and 5% of the bitumen content. It
is known that a mixture of asphalt latasir B with the addition of “waste rubber tire ‘can improve the
quality of Marshal. In the rubber content optimum for the ratio of 0312% rubber content and
asphalt content of 7.89%, resulting in a mixture characteristics: Marshall Stability 950 kg, Marshall
Quotient 4.1 kN/mm, Air Voids 3.5 % dan film thickness 8 μm.

Key word : Asphalt mixture Latasir B, and waste rubber tires, Marshall test
