▎ 摘　　要

NOVELTY - Preparing polymer modified asphalt (PMA) involves mixing compatibilizer precursor with polymer to obtain polymer concentrate, where polymer is mixed with compatibilizer precursor in weight ratio of polymer to compatibilizer precursor of 1:100-2:1; mixing polymer concentrate with asphalt to result in PMA. USE - Method for preparing polymer modified asphalt used in polymer concentrate formulation (claimed). ADVANTAGE - The method enables to produce PMA with uniformly dispersed polymer in asphalt matrix, and improves compatibility of polymers with asphalt. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a formulation, which consists of polymer; and compatibilizer precursor; where polymer, which is present in formulation in weight ratio of polymer to compatibilizer precursor of 1:100-2:1; and formulation, which is polymer concentrate.
