Asphalt binder content affects hot mix asphalt (HMA) mixture performance in the areas of strength, durability, fatigue life, ravelling, rutting and moisture damage. ABA – Asphalt Binder Analyser The ABA 7/35B is designed to measure the asphalt binder content of hot mix asphalt (HMA) using loss on ignition, in accordance with AASHTO T 308-10, ASTM D6307-10 & BSEN 12697-39:2012. The integral microprocessor controlled weighing and calculation system is configurable to allow variations to the standard test method. Test result reports are available in both printed and software format. The high temperature...

Hot mix asphalt (HMA) that has too much asphalt binder may experience problems such as, reduced skid resistance and reduced resistance to permanent deformation, eg rutting. HMA that has too little asphalt binder may experience reduced fatigue resistance and problems with stripping. Safe design • Failsafe door interlock keeps the door locked during a test even in the event of a power failure, protecting the operator from the burning test sample • Electrical supply is isolated from the heating elements when the door is opened • Afterburner temperature is controlled independently from the main chamber •...
