Advanced Binder Test

---

 The Pressure Aging Vessel (PAV) has been developed to simulate in-service aging of asphalt binder after 5 to 10 years. The binder is exposed to high pressure and temperature for 20 or 65 hours (selectable up to 99) to simulate the effect of long-term oxidative aging. 

  Rolling Thin Film Oven Test measures the effect of heat and air on a moving film of hot mix asphalt binder, simulating short-term aging that occurs during production and paving operations. 

 The Bending Beam Rheometer (BBR) provides a measure of low temperature stiffness and relaxation properties of asphalt binders. These parameters give an indication of an asphalt binder's ability to resist low temperature cracking. 

 Ring and Ball Apparatus is used to determine the softening point of bitumen, waxes, LDPE, HDPE/PP blend granules, rosin and solid hydrocarbon resins 

Rotational viscometers are designed to measure viscosity by analyzing the torque required to rotate a spindle submerged in bitumen at a constant speed. Calculations are made over time, allowing time-dependent analysis. 

 Used to determine the consistency of a bituminous sample under fixed conditions of load, time and temperature. The penetration is expressed in distance of tenths of millimeters vertically penetrated by a standard needle.

 Saybolt Viscometer is used to determine empirical measurement of Saybolt Viscosity of petroleum products at specified temperatures. 

 Used to determine the distance to which a briquette of molten bitumen can be extended under controlled conditions, before breaking 

Flash point testing is a procedure designed to determine the temperature at which flammability occurs in a sample or whether a sampled mixture of vapour and air is flammable.
