Due to poor bonding between pavement layers, slippage cracking appears as crescent-shaped (half-moon) or wave-like cracking. This type of pavement displacement can be caused by poor bonding of material with an underlying layer or a low-strength surface mix and may be exacerbated by continual traffic breaking or wheel turning.
Slipping asphalt will create rough riding surfaces, voids, and bulges and will begin incurring heavier and heavier impact forces from traffic, which will increase the damage. This will cause potentially larger damage later on, especially as water channeling and penetration damage the pavement base and advance the deterioration.
