A road is composed of multiple layers of material, each performing separate functions, from providing stability and strength to allowing for proper drainage. The surface of the road – the part we see – is merely one of those layers.
Just as our own skin protects our bodies from harsh elements that can compromise our health, the surface layer of a road protects the integrity of the layers beneath, which in turn, extends the road’s overall service life.
When we speak about preserving a road, we’re not only talking about the surface people drive on but, more importantly, the integrity of what lies beneath the surface.
That is why roads are designed to receive periodic treatments to protect the integrity of its multiple layers of material. To do this, KCRC has a “toolbox” of surface treatments from which to choose. Treatment selection is based on a variety of factors, including the current pavement condition, the ride quality, and the volume of traffic a road carries.
