What is Oxidized Bitumen 90/15? Oxidized Bitumen 90/15 is a semi-solid, thermoplastic petroleum bitumen product. It is made by blowing hot air into penetration-grade bitumen (usually 60/70), which yields a product of higher viscosity, thermal stability, and high adhesion. The numbers 90/15 represent its softening point (around 90°C) and penetration value (15 dmm), according to […]
What is Oxidized Bitumen 85/35? Oxidized Bitumen 85/35, or blown asphalt, is a semi-solid bitumen obtained from petroleum that is obtained by air-blowing bitumen 60/70 under regulated high temperatures. This increases its softening point and minimizes temperature sensitivity, and it is perfect for applications in construction that require it to be tough and withstand weather […]
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 […]
Definition of Oxidized Bitumen 75/35 Oxidized Bitumen 75/35 is an oxidized Asphalt produced by oxidizing a selected petroleum asphalts without adding the catalyst. Oxidized Bitumen 75/35 has high softening point, high flash point and it is highly stable during melting. As said before, Bitumen 75/35 is based on petroleum bitumen which is made by Blowing […]
