Hot bitumen is exactly that, Hot Bitumen. It is a liquid bitumen that needs to be heated to around 180°C prior to being sprayed. Hot bitumen is made in controlled bitumen plants and comes in a variety of different grades, the most common ones are Multi-grade and PMB’s.
Multi-grade bitumen such as C170 or C320 are most commonly used as spray seals on Australian roads.
PMB or Polymer Modified Bitumen is a bitumen blended with either a synthetic polymer or crumbed rubber. PMB’s come in varying types containing different percentages of rubber. The rubber content gives PMB bitumen increased elasticity and cohesion and has an improved crack resistance.

Unfortunately, due to emulsion being water based, these dodgy operators will add additional water, thereby diluting and weakening the strength and effectiveness of the emulsion. These operators are relying on most people not knowing the difference between quality and poor quality bitumen spray’s.
