Bitumen VG20 Description
Bitumen VG20 is a type of bitumen-a, a thick, black, sticky product highly popular in the construction industry because of its myriad uses, starting from road construction to waterproofing and roofing.
The “VG” in Bitumen VG 20 is an abbreviation of the term “Viscosity Grade,” while the number “20” defines its viscosity at 60°C.
Bitumen viscosity is the measure of resistance in flowing; it is one of the most basic properties of bitumen, as it dictates its uses for particular applications. Bitumen VG 20 is such a commonly used grade in the road construction activities, particularly for high-temperature areas, as it provides good resistance to rutting and deformation under high traffic loads.
Uses of Bitumen VG20
Bitumen VG20 is a road-laying grade of bitumen, specially designed to be laid on roads in cold weather and high-altitude areas, where the temperature is typically 30 to 37°C. It is optimally used for the production of hot mix asphalt for base courses and wearing courses, having excellent skid resistance and longer-duration durability. The grade also suits best for places like North India, where temperatures are low and bitumen of better workability is needed. In addition, VG20 enhances the flexibility of asphalt, reducing the chance of cracks in cold temperatures, and is therefore ideal for roads that are susceptible to temperature changes.
Difference Between Bitumen VG20 & VG30
Packing
Bitumen VG20 are in different packages including bulk,bags and drums .
New Steel Drums and its available in different sizes of 150 Kg,150 Kg, 180 kg,200 kg ,240 kg and any other customized sizes .
Jumbo Bag is other kind of bitumen packing and its in different size and Diamesion for example: 330 kg , 1000kg.
