Asphalt Content Tester
An Asphalt Content Tester, also known as an Asphalt Binder Ignition Furnace or Analyzer, is a laboratory instrument used to determine the percentage of asphalt binder (bitumen) in hot mix asphalt (HMA) samples. It operates on the principle of loss on ignition (LOI), where the asphalt is burned off at high temperatures (typically around 538°C or 1,000°F), and the weight loss is measured to calculate the binder content. This method is faster, more environmentally friendly, and cost-effective compared to traditional solvent extraction techniques, as it avoids the use of hazardous chemicals.
This process typically takes 30–45 minutes for standard samples, allowing for up to 5,000g at longer durations.
Standard Following
ASTM D6307, AASHTO T308.
