Benefits of GlobeCore Polymer Modified Bitumen Plants

Polymer modified bitumen is used for road construction

The intensity of freight traffic is rapidly growing every year. Proportionally increases the load on pavements. These conditions lead to irreversible deformations, degradation, brittleness, cracking and aging of roadways.

In this situation, a method has been developed to improve thermal  characteristics, fragility and tendency to aging – by adding special substances into bitumen. They are called modifiers, and bitumen obtained in this method – modified. The modifiers applied are  synthetic polymeric materials.

Introducing polymers creates a complex colloidal structure of bitumen,  changing its rheological characteristics:  temperature sensitivity, adhesion properties, elastic and strength characteristics. As well as decreasing deformation under load, and restoring elasticity.

A polymer-modifier added to bitumen absorbs the low molecular weight  fraction of the bitumen, reducing its volatility and increasing its strength. For technical realisation of modified bitumen GlobeCore  developed an installation UVB-2.

Polymer modified asphalt

Polymer modified asphalt plant includes: two reactors, colloid mill, an oil heater (used to heat the bitumen without damages), bitumen supply pump, polymer feed pump, bitumen valves, control cabinet, technological heating system, an input node of adhesive additive, plasticizer, and  polymer loading platform.

Mounted inside the heated colloid mill there are  movable and stationary discs, that allow to adjust the gap.

The control system works  the equipment, in both manual and automatic mode.

Advantages equipment for modified asphalt production:

UVB-2 Units have following advantages:

  • Can be used for administering all currently known polymers, waxes and various specific additives;
  • Work with a variety of forms of modifiers : powders, granules, etc .;
  • Allow to realize almost any bitumen modification chart;
  • During pumping and modifications other additional plasticizers and additives could be introduced that improve the adhesion of the bitumen;
  • In the pumping mode, there is the possibility of introducing additional quantities of polymer;
  • Oil heating system can reduce costs on electricity;
  • The ability to operate both  outside, under a canopy or inside.
