Chip seals can be used to protect an oxidized or weathered surface by sealing the asphalt to prevent moisture from entering the pavement structure. Chip seal is one of the industry’s oldest and most proven surface treatments available. The entire operation can be conducted with minimal traffic disruption.
EA-90P, EA-150 or HFE-150 can be also be used depending on the aggregate. Contact us for more information on using the right binder with the right aggregate.
Lightweight aggregate is produced by heating shale pellets to 450 degrees Fahrenheit. Shale expands to create a porous, lightweight aggregate. This is a good alternative when natural aggregates are not available or when complaints from the traveling public are a concern.
A chip seal will not increase the strength of an existing pavement. Chip seal will prolong the life of a sound pavement by providing a protective coating.
