Asphalt crack sealing materials must have good adhesion or bonding. They must be elastic yet resist softening. They must be easy to apply yet resist cracking, aging and weathering. Also, they must be compatible with asphalt pavement.
Asphalt emulsions, asphalt cements and fiberized asphalt are used for crack filling. Asphalt rubber, rubberized asphalt, low-modulus rubberized asphalt and self-leveling silicone are used for crack sealing.
