STRIPPING UNDER CHIP SEALS LRRB PROJECT NO 904

stripping of the upper ½ to 1 inch of hot mixed asphalt (HMA) pavements under chip seal surface treatments. The distress usually starts out as a small blister and develops to small potholes, at which point the chip seal delaminates from the pavement. This distress is an expensive maintenance problem. This appears to happen mainly on curb and ...

Investigating Asphalt Pavement Stripping Under Seal Coats

most premature stripping of chip seals. Underlying pavement may also offer some bond strength at the interface and may be damaged from multiple freeze-thaw cycles. Such seasonal wear can strip asphalt material from aggregate in the asphalt pavement just as it strips asphalt binder from seal coat chips.

Parking Lot Restriping and Seal Coating - FCAP

The asphalt binder (the glue that bonds the pavement together) usually starts to oxidize and weather over time, allowing moisture to penetrate the asphalt and cause damage to the pavement subbase. Other significant concerns for parking lot maintenance include oil, gas, and salt—these cause further substantial damage to the pavement surface.
