## Abstract
LASBUTAG is one of the surface layers in road construction which consists of a mixture of Asbuton, coarse aggregate, fine aggregate and rejuvenating material, which is stirred, spread out and cold compacted. The modifier used 60/70 penetration petroleum bitumen which was cured for ± 3-5 days until dilute petroleum bitumen and lawele granular asbuton were cured with pertalite for ± 24 hours to remove the bitumen content. Variations in the asphalt content used are 1%, 1.5%, 2%, 2.5%, 3% and 3.5% with 3 x 6 test objects for standard marshall 18 pieces and 6 pieces for Marshall immersion so the total test objects made of 24 cylindrical pieces with a volume of 1200 grams. The results showed that all Marshall characteristics obtained had an effect on Marshall Stability, VMA and Marshall Quotient, but had less effect on (VIM), from variations of 1%, 1.5%, 2%, 2.5%, 3% and 3.5% used for stability. The marshall, VMA, VIM and marshall quotient tested all met the standards except for the variation of 3% and 3.5% which did not meet the VIM values for the standards used. And from the variations that meet the stability requirements, VMA, VIM and Marshall quotient are 1.75% variation (Optimum Asphalt Content) and Marshall immersion index (IP) of 95.66%.
