Is Damaged Asphalt Endangering Your Andover Property?
In Andover, where large residential parcels meet the sandy soils and shallow water tables of Anoka County, unsealed pavement defects create silent, rapid sub-surface destruction. Autumn rain and winter snowmelt quickly enter surface fissures, soaking into the underlying base rock and sandy sub-grade.
J&W Asphalt stops this cycle using state-of-the-art infrared thermal technology. By reheating existing asphalt in place and fusing fresh hot mix directly into the repair zone, we produce a continuous, watertight barrier that permanently seals out groundwater without leaving cold, brittle saw-cut joints.
Here are the most common types of asphalt pavement damage we can repair and replace in Andover:
- Surface Cracking (Alligator & Hairline): Brought on by natural binder oil oxidation, intense sun exposure, and traffic stress over time. Untreated hairline fractures permit moisture to penetrate the sub-base, where seasonal freeze-thaw cycles turn them into webbed "alligator" failure patterns.
- Settlement & Low Spots: Occurs when sections of pavement drop below original grade due to sandy subsoil shifting or base rock erosion. These low areas trap standing water, which rapidly accelerates asphalt breakdown.
- Potholes (Full-Depth Failure): A complete structural breakdown where both the top asphalt mat and the underlying aggregate base have broken down. Potholes create severe vehicle damage hazards and tripping risks, requiring deep hot-mix thermal fusion to repair correctly.
- Edge Cracking & Raveling: Develops along exposed driveway perimeters and lot borders where lateral soil support has washed away. We rebuild compacted aggregate fill along the edge and thermally fuse fresh hot mix directly into the existing border.
