THE ADHESION OF BITUMINOUS BINDERS TO AGGREGATES UNDER HYDRODYNAMIC STRESS, AND ULTRASONIC TESTING IN SOLUTIONS OF DE-ICING SALT

A LABORATORY METHOD IS DESCRIBED WHICH ENABLES THE DECREASE IN BINDER CONTENT AFTER HYDRODYNAMIC STRESS TO BE DETERMINED. THE BITUMINOUS SAMPLE IS PLACED IN A SOLUTION OF DEICING SALT AND EXPOSED TO ULTRASONIC WAVES. THIS CAUSES PARTICLES OF THE BINDER TO DISSOLVE. TWO INTERESTING RESULTS ARE: 1 - THE AMOUNT OF BINDER WHICH DISSOLVES INCREASES AS THE SALT CONCENTRATION INCREASES; AND 2 - THE INCREASE IN THE DISSOLVING OF THE BINDER IS SIGNIFICANTLY DIFFERENT FOR EACH OF THE BINDERS USED. THE INVESTIGATIONS ARE TO BE CONTINUED. /TRRL/
