The ground to which the pavement is applied is the most important part of the sequence. Many areas of New Hampshire and Vermont have different types of soil, so the sub-base quantity will vary from region to region. A minimum of six inches pf crushed gravel is a must. Remember, pavement is only as good as the material it is applied to. Asphalt minimum thickness should be two inches compacted over crushed gravel. A thicker application of asphalt is recommended in high traffic areas.
Cracks in pavement are inevitable. The northern winters are brutal and frost will move any ground. That is why it is so important to maintain new pavement. We recommend seal coating your new driveway in the first 12 months to help insure its durability.
