The durability of a bitumen pavement greatly depends upon the ability of the bitumen to adhere to the aggregate in the presence of water. Loss of adherence between aggregate and bitumen causes deterioration of the road in an early age. Stripping of bitumen from the aggregate has been limited to cold mixes only, using cut backs. In such cases anti-strip additives may be used with bitumen, to improve the bond between aggregate and bitumen.
