Asphalt pavement is made up of fine stone or sand, and asphalt cement. The asphalt cement is what gives the pavement its black appearance is the “glue” that holds everything together. New asphalt is jet black but soon begins to fade. That’s oxidation; this is the effect of sun, rain and snow oxidizing the asphalt cement in the pavement. Given enough time the pavement becomes brittle and has less resistance to the loads placed on it. Asphalt is a petroleum product so any other petroleum derivatives that contact it will dissolve into the asphalt, weakening or dissolving the “glue-like” properties. These products commonly include motor oil, transmission/power steering or brake fluids, gasoline and perhaps household solvents. A good quality sealcoating will protect the asphalt from all these damaging factors while providing curb appeal. McKenzie Paving Inc. provides this service at a fair price.
