Technology of asphalt pavements by asphalt oil started 170 years ago, with an experiment involving natural rubber with bitumen in the 1840s , attempting to capture the flexible nature of rubber in a longer lasting paving surface. Now a days especially rubber process oil use instead of natural rubber for bitumen rubber blend as asphalt oil for pavement.
Nowadays the rubberized asphalt technology is being adopted in many other parts of the world: Taiwan is pioneer inasphalt mixtures for flexible pavement rehabilitation; furthermore, rubberised asphalt oil has been trialled in Beijing and for use in new and maintenance work as part of the preparation for the 2008 Olympics in China and it has also been used in EcoPark Project in Hong Kong.
Bitumen flux rubber blended oil
On the basis of first positive experiences also Brazil and Sudan are strongly investing in the application of this technology for road pavements.Modified bitumen increase viscosity of bitumen flux rubber blended oil should blend with penetration bitumen grades 60/70 or 80/100 to provide a product with a particular viscosity and other prescribed properties.
This product is well know as Extender Oil – Asphalt Oil – Bituminous Oil – Bitumen Oil – Modified Bitumen Oil – Asphalt Rubber Oil – Bitumen Blend Tyre Oil .
