An asphalt overlay or new asphalt installation is a fresh start for your property’s first impression. Nothing beats the feel, noise reduction, and look of a newly paved parking lot or roadway!
The preparation for an asphalt overlay should be assessed by a professional to see the extent of asphalt milling, base repairs, leveling, and drainage considerations needed to create the right paving base for a long overlay life.
Binder or Base Course
The binder or base course of asphalt is load-bearing and a heavier aggregate mix of hot mix asphalt pavement. This first layer of asphalt on the base material has aggregate up to ¾” or 1” to provide a high-strength, flexible paving course that can last up to 30 years.
This intermediate course does not make for the smoothest ride, which is why it is laid beneath the surface course, but it is essential for a long-lasting, properly functioning pavement surface.
Surface or Wearing Course
The top layer of asphalt that comes in contact with traffic is the surface or wearing asphalt course. This top course of asphalt contains aggregate that does not exceed 0.5” to provide a smooth, noise-reducing, driving, and walking surface. The pliability, workability, and strength of surface hot mix asphalt make it the preferred medium for correcting asphalt ADA parking fields and transitional areas.
Our paving, loot, and roller operators match and compact every joint to perfection. By taking the joint integrity seriously with every paver pass, we ensure a seamless driving surface and the prevention of longitudinal cracks.
We pay special attention to hitting the right grades during the paving process, installing a leveling course to add stability and depth of asphalt to low areas preventing water ponding or pooling.
