polymer itum

Bitum 45-80/65 and 25-55/55 are a premium grade polymer modified bitumen that can be adjusted to meet the most severe requirements of the European paving projects.

Bitum 45-80/65 and 25-55/55 can be used in various asphalt mixtures to improve a number of specific characteristics of the asphalt mixtures in which it is applied.

Performance properties of the asphalt that are improved are:

  • Increased resistance to permanent deformation (pavement rutting) due to the increased viscosity and elasticity
  • Resistance to cracking and raveling because of the increase in bitumen flexibility, which allows the asphalt to absorb mechanical and thermal stresses
  • Better adhesion between bitumen and aggregate
  • Improved performance at lower temperatures because of the increased flexibility over a wide range of temperatures
