Polymer modified Bitumen System
It has been designed for modifying bitumen with polymers, with special focus on hot mix asphalt for road, railway, and airport building.Production of hot asphalt mixes with Polymer modified Bitumen (PMB) is mandatory for enhancing the performance of bitumen used in road, runway and racetrack applications both by improving life expectancy and reducing maintenance levels.
There are 4 important issues for good quality PMB:
Bitumen quality, polymer compatibility (the most used polymer is SBS), mill performance (a high quality mill with high power is fundamental to grant the perfect blending of polymer and bitumen) and good agitation of the final product (which is guaranteed by two/Three agitators in each tank).The plant is specially designed for polymer modification of bitumen with a capacity up to 40ton/h (theoretical capacity, with 5% SBS granular polymer and bitumen temperature at 180°C) and is fitted into a containerized body for stronger structure and easy transportation.It is very flexible and can be adapted to any jobsite thanks to its special lay-out. The batch production can vary from 1 to 6 tons, and the number of passes through the mill can vary, depending on the percentage of polymer required to modify the bitumen.
