The bituminous material is more often asphalt material whose viscous nature form allows significant plastic deformation. Prime Coat: It is low viscous cutback bitumen to an absorbent surface like granular bases on which the binder layer is placed on the road layer. The prime coat provides bonding between two layers together. The methods

1 The maximum temperature for cutback asphalt shall be that at which fogging occurs. The FAA allows use of materials listed in Table 1. Highways recommends Type SS-1 or SS1h. If cutbacks are specified in the Special Provisions, their use is limited. Prime coats are only applied to untreated aggregate base prior to placing bituminous concrete.

The different materials are used for base courses such as crushed stone, crushed slag, and other untreated or stabilized materials. 4. Prime Coat. A prime coat is applied by spreading low viscous cutback bitumen to an absorbent surface like granular bases on which the binder layer is placed. It is primly used to provide a bond between two layers.

Major use for Cutback bitumen is in the road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course. Its purpose is to bind the granular material of the base course to the asphalt layer. Usual application is by spray using a distributor. Other uses include the following:
