Chip Sealing

Chip Sealing

Chip Seal: (Oil &Stone) 
Chip seal driveways have been in existence for over 100 years. There are two types of Chip sealed driveways.

Type I: 
Over a compacted base we recommend 6/8 “ of process gravel compacted . Based on soil conditions it could be as high as 12“. To achieve proper compaction the base should be damp. A heavy oil is then applied. A light coating of aggregate stone is then spread on the oil and then lightly rolled in place. This process is repeated a second time.

Type II: 
Removing asphalt or if asphalt is in good condition will be decided by inspection. We may apply the oil process over the existing asphalt. Repairs may be made to existing asphalt such as crack filling, cutting and patching small pot holes and a general clean up. Remember if your driveway is crumbling or sinking the driveway is only as good as the base below it. If we need to re-move the old driveway we will regrade and add up to 6/8” of compacted process gravel. We then apply 2” of compacted asphalt. We usually wait 30 days after the asphalt is applied to apply the stone process. The reason for the wait is to allow the oil in the asphalt to balance off the top and allow tracing oil to bond to the asphalt. After tracing oil is applied stone is spread and lightly rolled in place. We suggest staying off the driveway for two to nine days to ensure proper curing.

New driveway or additions to your existing driveway: 
After the driveway has been marked out for the new or addition to your old driveway we excavate 8-10“. This is based on soil conditions. After excavation 1 ½ to ¾ process gravel is used to ensure good compaction. The stone is applied in lifts, usually 2 to 3“ at a time, with compaction after every layer is applied. The top layer is usually ¾ compacted. We recommend waiting 6 to 8 weeks before paving to ensure settling and compaction.
