What is Oxidized Bitumen 105/15? Oxidized Bitumen 105/15, or Blown Asphalt 105/15, is a semi-solid bitumen material produced by blowing hot bitumen with air. This oxidative process increases the softening point of the product and decreases the penetration value, making it more hard and heat-resistant. With a softening point of approximately 105°C and penetration of […]
