Oxidized bitumen<\/strong><\/em> or blown bitumen<\/strong><\/em> is produced by blowing hot air into pure bitumen<\/strong><\/em> in the final stages of its refinement. In this process, the manufacturers blow hot air<\/strong><\/em> at the temperature of 200 to 300 Celsius through a perforated pipe into the bitumen container<\/strong><\/em>. As a result, the hydrogen atoms in bitumen\u2019s hydrocarbon molecules<\/strong><\/em> combine with oxygen. Consequently, they result in water polymerization of bitumen<\/strong><\/em>. In this article, we will explain more about the properties of blown bitumen<\/strong><\/em>, blown bitumen uses<\/strong><\/em> and the types of blown bitumen. We will also explain more on what is blown bitumen<\/strong><\/em>.<\/p>\r\n

What is oxidized bitumen?<\/h2>\r\n

First of all, let us see what is blown bitumen<\/strong><\/em> definition and how it is made. Oxidized bitumen<\/strong><\/em>, which is also called blown bitumen or blown asphalt, is a substance that manufacturers produce from petroleum at high temperatures by instigating controlled chemical reactions of air or oxygens. This process makes the bitumen<\/strong> sticky and harder<\/strong><\/em> than before and improves its heating properties.

The manufacturers can change the bitumen oxidation degree<\/strong><\/em> to produce a wide range of bitumen products<\/strong><\/em> that have different properties such as increased softening point, reduced penetration degree and improved resistance to air and oxidation. Blown asphalt<\/strong><\/em> has many uses in roofs, humidity insulations and producing Industrial products like adhesives<\/strong><\/em>, covers<\/strong> <\/em>and sealants<\/strong><\/em>.<\/p>\r\n

Solid blown bitumen<\/strong><\/em> is a type of bitumen that manufacturers make by blowing air into pure bitumen. Therefore, it has a lower penetration degree and higher softening point.<\/blockquote>\r\n

\"What<\/p>\r\n

How do you make oxidized bitumen?<\/h2>\r\n

Blown asphalt<\/strong><\/em> is the result of constant blowing into normal bitumen. First, the manufacturers heat the penetration degree bitumen in a controlled environment. Then, they blow air into the bitumen to control the petroleum content in it when it is oxidized. Different oxidized bitumen grades<\/strong><\/em> are used for different purposes.<\/p>\r\n
