New material that makes it possible for trial mix to modify concrete-asphalt (LASTON) is used tires waste. Used tires are useless waste of vehicles. In Indonesia there are a lot of used tires and its benefit is very limit. On this research carried out to used tires waste with variation 0%, 1%, 2%, 3%, 4%, 5%, and 6% and made 3 samples for each variation, using Concrete-Asphalt Method on Asphalt Concrete Wearing Course (AC-WC) layer, with asphalt rasio plan (Pb) 5,55%. The best used tires waste mix compotition that showed on Marshall Test from 7 sample variations is on rasio 1% with value of VIM 4,88%, value of VMA 16,55%, value of VFA 70,56 %, value of Marshall Stability 1886,13 Kg, value of melt (Flow) 3,43 mm, value of Marshall Quotient (MQ) 546,27 Kg/mm.
