Different to asphalt, spray seal is a rougher surface that is formed by spraying
a layer of water based liquid bitumen and then covering the liquid layer with a layer of aggregate (the size of the stone varies according to the usage of the surface). A bitumen spray seal is usually a two-coat system. Liquid bitumen is sprayed onto a prepared road base surface. A 14mm aggregate is spread in a uniform layer and rolled with a rubber tyred roller. A second coat of bitumen is sprayed, followed by a layer of 7mm aggregate (which fills the voids between the aggregate of the previous coat) and then rolled. The surface texture of a spray seal is coarse with an amount of excess (or loose) stone on the surface. This is usually left and will bed in over time.
