After installation, how long should I wait to put vehicles on the asphalt?

Typically overnight. You should expect some “scuffing” of the new surface, especially during the warmest months and in areas where vehicles are stopping and making sharp turns. These visual imperfections will disappear over time as the surface seasons and becomes less pliable. The most prone area for damage is where the vehicle reverses out and stops, the wheel is then turned from hard left to right (or viceversa) while the car is stationary and it “scuffs” the asphalt. Tyres are designed to stick to asphalt.
