The primary cause of asphalt failure is the penetration of water into the asphalt base.  This process begins with the oxidation of the pavement surface which causes the asphalt to dry and become brittle.  As your asphalt begins to crack, if left untreated, they will allow water to penetrate to the base of the pavement which causes the base material to move and settle leading to further cracking and low spots.  Sealcoating seals the asphalt pavement, preventing oxidation and erosion and protects your asphalt from the sun and harmful effects of chemical spills such as oil and gasoline.  Sealcoating costs pennies a square foot compared to the dollars needed to repair or replace damaged asphalt.
