Surface Treatments
Adding a surface treatment to a road surface optimizes its quality and extends its life. Gecan provides a selection of chip seal surface treatments, including:
Single
A basic chip seal treatment, where one layer of asphalt binder and one layer of aggregate are used to resurface the roadway.
Double
Similar to a single chip seal treatment, but with two layers each of binder and aggregate for added durability.
Racked-in
A layer of choke stone that is applied to temporarily protect a single course chip seal from damage. The choke stone helps hold the aggregate together while the binder cures.
Sandwich
A method where large aggregate is covered with a layer of emulsion, and then a layer of finer aggregate. The emulsion and fine aggregate seal in the large aggregate, making it more durable and long-lasting.
