Tar and bitumen, specially cutback bitumen, are flammable liquids at high temperature and therefore, there is a risk of catching fire if care is not exercised during construction. The Flash Point of bitumen is determined by Open Pensky- Martens Method. In this method, a small cup filled with bitumen is subjected to rise in temperature at a specified rate. A small flame of 0.16 in. diameter is applied to the surface of the cup containing molten bitumen at specified intervals until a flash first appears at any point on the surface. That particular temperature is considered as the Flash Point.
