There are some important steps in a successful resurfacing application that occur months before the product is actually applied. If your subdivision is scheduled for resurfacing this year, County Road and Bridge crews have already, or will be shortly, started preparing your streets for resurfacing operations that will occur next Spring or Summer.
In preparation for the resurfacing, County crews perform the following operations:
Sweep the streets to remove loose debris to better analyze the condition of the road.
Assess the street conditions and determine if there are any locations where the road base (foundation) has been overly stressed and failed. Failed material is removed and replaced with fresh road base material and a patch.
Seal larger cracks that need to be filled prior to resurfacing. Road and Bridge crews use a hot applied rubber product to fill the cracks and seal them off. While some residents might consider the resulting crack sealant to be unattractive, it is very successful at preserving the integrity of the street. Crack sealant is often applied during colder months when the crack is wider due to thermal contraction.
Spray herbicide on the shoulders of the road. Root systems from grasses and weeds assist in the crack proliferation of the roadway surface and should be removed prior to resurfacing.
Trim and remove tree limbs that will impede the large construction equipment during resurfacing operations.
Apply a cold paving material by spreading it on the roadway to level uneven spots and repair the shoulder. This process requires larger equipment such as motor graders, haul trucks and rollers to maneuver and perform a finish type work on narrow streets and roads.
Once all of these preparatory steps have been performed, the binders in the sealants and leveling products need time to cure. You might not see any maintenance activity again until we are ready to resurface the roadway with a seal coat or fog seal.
Road and Bridge crews will notify residents in advance of the work by door hangers, flashing message signs or static message signs.
