  • All of our SBS and SBR asphalt modification products are designed to increase pavement life 3 to 7 times.
  • Our asphalt modification products are engineered to blend seamlessly with bitumen, a binding agent often used in asphalt.
  • We offer technical assistance and cutting-edge laboratory support to all of our clients.
  • All of our asphalt/bitumen products are versatile and provide excellent benefits for the cost.

The Benefits of Modified Asphalt

The adhesive characteristics of traditional asphalt make it the preferred binding agent for highway construction, sealants and waterproofing, since these characteristics enable it to hold the aggregate in place. Modified asphalt – particularly asphalt modified by Dynasol's styrene-butadiene copolymers – can deliver improved weather resistance, reduce cracking and rutting, and greatly increase time between repaving or reconstruction.
