Description of Oxidized Bitumen 95/25
Oxidized Bitumen 95/25 is based on petroleum bitumen which is made by Blowing Grade 60/70 bitumen by hot air.
Blown Asphalt 95/25 is the semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction business. The softening point value measured by Ring and Ball method as determined by ASTM D36. Also, the penetration value is in 1/10 mm as determined by IP49 or ASTM- D5. Oxidized bitumen has a higher softening point than viscosity grade and penetration bitumen. Consequently, oxidized bitumen is less susceptible than penetration bitumen and viscosity bitumen to temperature changes.

How is the 95/25 oxidized bitumen blowing process performed?
The production involves a bitumen blowing process, where oxidation, dehydrogenation, and polymerization occur simultaneously. The oxygen in hot air reacts with the bitumen, forming hydroxide, carbon, acid, and ester groups that enhance its physical and chemical properties.
Application of Blown Asphalt 95/25
Oxidized bitumen 95/25 has a wide range of applications in various industries, such as chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack sealing and repair, civil engineering, roofing, and general construction.
It is used for sealing and insulating buildings, as an adhesive, an additive in construction materials, a dust-binding agent, and as an insulating and impregnating material. It is also used in the production of rubber and plastic products.
Bitumen 95/25 oxidized finds a very wide application in paving, corrosion protection of metals by asphalt varnishes, and lining of public works. These also serve as adhesives in electrical laminates and as a base for synthetic turf. Their normal uses include waterproofing, pipe coatings for corrosion resistance, Portland cement pavement, hydraulic works, paint manufacturing, caulking, mastics, and damp proofing. More importantly, bitumen 95/25 is also used to manufacture insulation and isolation membranes.
Blown asphalt, on the other hand, has great importance in the car undercoating industry. Undercoating materials based on bitumen possess excellent qualities of waterproofing, dust resistance, and noise insulation that protect car surfaces from harsh environmental elements.
Storage and Handling of Bitumen 95/25
Oxidized Asphalt 95/25 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. Please refer to MSDS for more information.
Health & Safety of Oxidized Asphalt 95/25
Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline.

FAQs
1. What is the suitable climate for Oxidized Bitumen 95/25?
Since the softening point is higher in Oxidized Bitumen 95/25, it is highly suitable for moderate to warm climates, as it does not readily get affected by increased temperatures. It retains its shape in higher temperatures and resists cracks at low temperatures, so a wide range of environmental conditions suits it.
2. What is the life span of Oxidized Bitumen 95/25, and what are the parameters that affect its durability?
The average life span of Oxidized Bitumen 95/25 is between 15 to 20 years. However, factors such as the quality of the bitumen, application method, climatic conditions, and resistance to chemicals and UV rays also determine its durability. Proper care and following standard methods during application can greatly increase the life span.
3. What determines the price of Oxidized Bitumen 95/25?
Some of the key factors affecting the price of Oxidized Bitumen 95/25 include the quality of raw materials used in production, the process of oxidation, and transportation costs, given that this product is heavy in weight and requires special packing. Moreover, market demand controls its price; where there is high demand for the product, its price fluctuates. Currency exchange rates also might affect the price in the international market. Products with specific certifications, features, or special formulations might be more expensive due to the value addition and regulatory compliance involved.
4. Does this product have any environmental certifications?
Yes, many renowned manufacturers of Blown bitumen 95/25 supply environmental certification of ISO 14001 or similar standards, proving the production is conducted with accordance to environmental consideration and environmental pollution is just minimal. One can surely ask relevant certification from suppliers for environment friendliness of the products.
