Description of Oxidized Bitumen 115/15

Oxidized bitumen 115/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. The most oxidized bitumen usable grade is bitumen 115/15 and 70% of our capacity is dedicated to this grade. Bitumen 115/15 is a semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons and oxidized bitumen normally used for different purposes in the construction business. Bitumen Malaysia’s oxidized bitumen 115/15 has high softening the point, high flash point and it is highly stable during melting.

Bitumen Malaysia’s oxidized bitumen 115/15 a bituminous product manufactured by the special process of non-oxidization but modification of vacuum bottoms at 230 °C temperature, resulting in a material of a much higher penetration index. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides superior adhesive and waterproofing qualities when applied hot and allowed to cool than oxidized bitumen.

Bitumen Malaysia guarantee the quality of our oxidized bitumen 115/15 with the arrangement of the international inspectors to check quality and quantity of our oxidized bitumen 115/15 during the loading to the vessel and controlling the production by QC by batch test report before shipping. Bitumen Malaysia guarantees the quality to meet with ASTM standard.

Uses of oxidized bitumen 115/15

Oxidized bitumen 115/15 is used as raw material for bitumen coat, the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, crack seals and repairs, civil works, construction industries; pavement, sealing and insulating buildings, insulation and isolation bitumen membrane sheet, adhesive, construction materials additive, dust-binding, coating, insulating and impregnating agent, to manufacture rubber and plastic products. Oxidized bitumen 115/15 products are for paving, roofing; also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, the base for synthetic turf; typical uses for bitumen 115/15 include roofing, pipe coating, hydraulic applications. Most bitumen 115/15 used to produce “mopping-grade” roofing asphalts. The special usage of oxidized bitumen 115/15 is bitumen paint manufacturing and oil well drill fluids. Oxidized bitumen 115/15 is used in roofing manufacturing plants to produce shingles, roll goods, built-up roofing felts.

Application of oxidized bitumen 115/15

Oxidized bitumen 115/15 should be heated double temperature against the softening point to be able to have flow and viscosity. Normally oxidized bitumen 115/15 is heated up to 230 °C while it is in bale. However, if it is inside of bitumen bag,  we will require 50 °C more to melt the bags.
Before using oxidized bitumen 115/15 surfaces must be dry, clean and free of loose particles, curing products, irregularities, and slurries. If you use this types of bitumen without cleaning the area first, it will easily be removed.

Storage and handling of oxidized bitumen 115/15

Oxidized bitumen 115/15 has 10 years validity with multi-time heating and cooling, please refer to MSDS. It is better to keep the bitumen 115/15 under shelter and out of the rain and sun.

By mopping or by the pour-and-roll method, it should be heated to a temperature between 180 to 200 °C.

Packing of oxidized bitumen 115/15

Oxidized bitumen 115/15 is available in bulk, drums, meltable bags and craft bag. Oxidized bitumen 115/15 are generally shipped as a solid and heated in a kettle at the worksite.
