Salt Air and Humidity Accelerate Charleston Pavement Decay
Coastal humidity keeps asphalt pores saturated longer after storms, while salt air accelerates oxidation on parking lots near harbor corridors. The combination shortens sealer life and promotes subgrade softening.
Historic Charleston properties must balance modern ADA compliance with aesthetic standards. Faded crosswalks, illegible fire lanes, and uneven brick-adjacent transitions create both code violations and guest safety risks.
Tourist retail lots along King Street and Mount Pleasant see seasonal traffic spikes that expose under-maintained pavement. Proactive crack filling and striping before peak season prevents emergency closures.
