Bitumen and asphalt modifying polymers with Plasfa brand is a product proposed by Beta Polymer Fardangar Company, which is the result of interdisciplinary cooperation and multi-year specialized research in the fields of road engineering and polymer. With the production of PLASFA products, the knowledge of producing a specific polymer that improves and improves the functional properties of bitumen and asphalt according to customer needs, geographical climate, road conditions and asphalt production process has been obtained. This achievement has brought benefits such as increasing the lifespan of asphalt, reducing road maintenance and repair costs, optimal use of oil resources, preserving natural resources and the environment, and contributing to the sustainable development of transportation infrastructure.
