What is Oxidized Bitumen 90/15?
Oxidized Bitumen 90/15 is a Semi Solid type of pure petroleum bitumen manufactured by manipulation of hot air-blowing through an asphalt flux.
The numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36 Standards and regulations. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.
Oxidized Asphalt 90/15 is based on petroleum bitumen which is made by blowing grade 60/70 bitumen by hot air.
Our sales team is committed who understands your requirements due to many years of experience in supplying the bitumen products.

Application of Oxidized Asphalt 90/15
his kind of bitumen is suitable to be used in the chemical, raw material for bitumen coat, paper-pulp-board, textile processing, pavement, crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products.
typical uses for Bitumen 90/15 include roofing, pipe coating, hydraulic applications, 90/15 is mainly using in paint manufacturing and coating in hot area.
Storage and Handling of Oxidized Bitumen 90/15
Blown Asphalt 90/15 is best up to 10 years from the day it was manufactured. It is suggested for higher time of warehouse keeping to keep the bitumen under shelter and out of the rain and sun shine.
Health & safety
Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline.
Packing of Oxidized Bitumen 90/15
Blown Asphalt 90/15 in various packing, including bitumen 90/15 is available in 20 & 50 Kg Kraft Paper Bags 25 Kg Carton box & 150, 180, 200 Kg Steel Drums:
25kg carton box
25kg mold packing
It is most expensive packing since there is mold on and with same mold we can ship out. The mold is carton and at destination you can remove the mold easily.
25Kg Polyamide bag
It is heat resistance bag and filling directly in water to cool down fast. It is firstly use not possible to take out the Polyamide from the bitumen and then use.
25kg craft bag
Craft bag is recycle packing and inside is special material to prevent sticking the bitumen to bag. This grade also possible to load on pallet or without pallet for customer.
