MB1000 Series was developed by ART for the booming requirement in the early 2000’s when CRMB and PMB was being introduced. These entry level Modified Bitumens provided a quick suitable fix to issues faced by contractors and surpassed the basic binders in performance, especially in high temperature zones.
