The asphalt used in modified bitumen sheets is modified asphalt, which is of two types: SBS modified and APP modified asphalt. What are the differences between the two?

What will be an ideal response?


SBS modifier is synthetic rubber, which makes an SBS-modified bitumen sheet quite flexible and more resistant to cold temperature. APP modifier has greater resistance to ultraviolet radiation, and hence, an APP-modified bitumen sheet is relatively more durable.
