We all know that water is the most destructive element to our pavements. If it rained and snowed
everywhere but on our roads and bridges, 90 percent of highway and street work would be
eliminated. Since that is not likely to happen any time soon, we need to prevent water intrusion
into our pavements. Filling or sealing pavement cracks to prevent water from entering the base
and subbase will extend the pavement life by three to five years.
