Once a road has deteriorated to a point where preventative maintenance is no longer a viable option, then other corrective actions become necessary. Each road is different. Roads have different traffic loadings, different soil conditions, different existing materials in the pavement structure, and different drainage characteristics. By analyzing the existing road conditions, we determine whether to improve, replace or construct pavement structures underneath the roadway surface on a case by case basis. The worst case scenario for corrective actions involves total reconstruction. The time, equipment and material costs associated with total reconstruction are many times greater than preventive maintenance. That is why preventive maintenance is so important.
