Proper Bonding

Jul 26, 2021

Slide reads Task 2 - Pavement Bonding (Tack Coats & Bond Strength Test), with immages of defromed pavement. A graphic shows how tension between two layers of pavement that are not properly bonded creates space for friction. Bullet points read: Pavement construction requires construction layers in "lifts." Pavement design is conducted assuming layers are "fully bonded," Poor bonding in HMA layer is associated with, reduced fatigue life, increased drutting, and slippage, cracking, and instability.
