Binder extraction and recovery is important for both determining the binder content and recovering a representative sample which can be used to perform other tests such as penetration, softening point, etc. The machine used is a Pavelab Systems product, by Controls.
The wheel tracking test is used for determining the susceptibility of Hot Mix Asphalt (HMA) to deform under load by measuring the rut depth formed by repeated passes of a loaded wheel at a fixed temperature.
The penetration test is used as a measure of consistency. Higher values of penetration indicate softer consistency. PAVELAB SYSTEMS Pivot is able to perform this test automatically and it features a very accurate zero point determination to eliminate any operator error.
