UVB-2 Small Plant for Modified Bitumen production, the capacity = 4 cubic meters / hour

UVB-2(4) Modified Bitumen

Modified Bitumen. The UVB-2 bitumen modification plant is designed for modification of bitumen by adding polymers, adhesion additives and plasticizers into viscous road bitumen. Modified bitumen is used in production of asphalt/ concrete top layer, cement protection layers and crack sealants.

The use of modified bitumen instead of regular bitumen in asphalt concrete mixes allows to extend temperature range of asphalt concrete layer operability with seasonal temperature fluctuations, ensures load deformation resistance (crack and rut formation), increases general service time of automobile roads.

The unit is designed for implementation of virtually any bitumen modification process using a wide range of polymer modifiers (polymers, waxes etc).

The compatibility of bitumen and polymers is essential to obtain a high-quality final product. In such a case, the polymer is able to absorb oil components of the binder, preserving the network structure. Due to the modification process, bitumen is turned into an elastomer that possesses better elasticity.
Modern petrochemical industry professionals attempt to maximize the yield of light oil products and extract most of the paraffin-naphthenic fractions from the bitumen. This reduces its flexibility at low temperatures and reduces the softening point at high temperatures. Most modern bitumen will lose elasticity at approximately twenty degrees (20oC) and begin to soften at between +45oC to 48oС. The use of non-modified bitumen therefore, in both road construction, which requires a binder with a temperature range from -40oC to +70oC, and for roofing materials, which are often subjected to temperatures up to 90oC, is not efficient. Fortunately, there are ways to change and improve the properties of bitumen by mixing it with various additives. This is best achieved in special bitumen modification units such as the GlobeCore UVB bitumen modification system.
