Polymer Modified Bitumens
Polymer modified binders deliver outstanding performance in a range of sprayed seal and asphalt applications.
Why use PMBs?
Polymer modified binders (PMBs) are generally considered to provide prolonged life or enhanced pavement performance. In sprayed seal and interlayer (membrane) applications, polymers can greatly prolong pavement life by inhibiting reflection cracking. In dense-graded asphalt applications, PMBs are effective in reducing rutting and improving fatigue crack resistance.
The higher shear resistance provided by PMBs can give beneficial effects in roundabouts, tight corners and
other high stress areas. Polymers have also demonstrated the ability to prolong the life of open-graded surfacings by allowing thicker binder films, which are less prone to oxidation and tougher films that resist collection of foreign matter and dust, thus maintaining the desirable water drainage capacity of these mixes.
The role of a PMB varies in each different application. Also, the different PMBs work in different ways. It is therefore very important to choose the correct binder for each application and it is equally important to design the mix or seal correctly.
