Major and Local Streets receive this treatment in an effort to preserve each for approximately 7-10 years. The treatment consists of placing a ½” asphalt micro-surface over an existing asphalt street. The process generally takes less than one day to complete.
This process involves placing a new hot asphalt surface over the entire street or possibly just the driving lanes in some cases. These processes hold a street together for approximately 7-10 years when the street receives a new 1 to 1 ½” over-lay curb to curb.
This process involves placing a 3-inch wide hot asphalt seal over a visible crack in the asphalt or concrete. Applied crack sealing keeps as much water out of the subgrade as possible. Stress cracks can appear as soon as one year after a street is rebuilt. This is not unusual in the type environment we experience in the Great Lakes region. This preventive maintenance measure provides water protection. It does not provide any structure improvement to the pavement.
