Polymer-Modified Asphalt (PMA) enhances standard asphalt by blending polymers (like SBS, EVA) into the bitumen to significantly improve road performance, offering superior resistance to rutting, cracking (hot & cold), and fatigue, thereby extending pavement life and reducing maintenance costs despite higher initial investment. PMA creates more durable, resilient pavements suitable for heavy traffic and extreme climates, often using simpler production methods (like one-plant systems) and reducing energy use compared to older Polymer Modified Bitumen (PMB) approaches, leading to better lifecycle cost savings.
