Unformatted text preview: process. The airflow meters in the over are calibrated and the material is heated for a certain time and rotated before the change in mass is measured. In RV, the material is applied around a steel cylinder that is inserted into another at a temp controlled by a water bath and the torque required to spin in is measured to test for construction properties. In DSR, a plate size and gap are selected based on temp and the spindle oscillates at a certain speed and torque and deflection angle are measured to test for elasticity. An asphalt emulsion is a suspension with water and an emulsifier. Cutback is mixed with a volatile oil....
