Performance Grade PMB Binders are a special grade of Bituminous Binders based on SuperPave Binder Test and specifications. Its measured lab testing relates to Field Performance. These are rigorously tested with various high-end equipment available with ART in-house (such as Rolling Thin Film Oven (RTFO), Dynamic Shear Rheometer (DSR), etc.) to simulate the performance of a binder at three critical stages:


1. Change in Bitumen properties while transporting, storage and handling prior to mixing with aggregates,

2. Change in Bitumen properties after HM operations and Construction (short term ageing),

3. Change in Bitumen properties after long period of time in service.


The tests are designed to control the pavement with 3 specific types of pavement distresses; rutting, fatigue cracking and thermal cracking. This gives a practical result to the performance of a binder and helps overcome the difficulty in relating empirical tests and performance of pavements.


The results of the test are given in a clear and easy to understand format. For Example: PG76-22 implies that the particular binder will perform in a region with an annual 7 day maximum average temperature of 76֯c and a single day annual minimum temperature of -22֯c. Beyond these parameters, the binder will be unable to perform optimally and over long exposures.


This simple yet highly effective way of identifying the optimal binder enables development of highly customizable solutions that are best suited for a particular site.
