Sub-grade deficiencies or old & damaged pavement may require removal of part or all of the pavement and base material. Once the pavement is removed pre-existing conditions in the sub-grade such as excess moisture, poor aggregate base, or poorly prepared sub-grade may require additional base preparations. These conditions are usually not discovered until the overlying asphalt is removed.
After careful inspection Hall Brothers, Inc. can recommend the most effective methods to resolve these conditions.
When pre-existing conditions have been corrected, the base is then prepared as needed and re-compacted. The new asphalt is then placed.
