Chip seal aggregate is a mix of small, uniform-sized stones and liquid asphalt used in road construction. It’s applied as a top layer over existing asphalt to enhance durability and provide skid resistance. The aggregate chips become embedded in the asphalt as it cures, creating a textured surface that improves traction and extends pavement life.

FAQs
How do I know how much aggregate I need? The amount of aggregate you need depends on the specific project and its dimensions. To estimate, measure the length, width, and depth of the area you want to fill with aggregate (in feet) and then use the formula: Volume = Length x Width x Depth. Convert the volume to cubic yards (1 cubic yard = 27 cubic feet) for aggregate ordering.
How do you calculate aggregate tonnage? Aggregate tonnage depends on the density of the material. On average, one cubic yard of aggregate weighs approximately 1.3 to 1.4 tons. So, to calculate tonnage, divide the cubic yardage by this weight factor.
How much tack coat per square meter? A general estimation is that you’ll need about 0.05 to 0.1 liters of tack coat per square meter. This can vary based on factors like the type of tack coat and surface condition.
How much recycled asphalt do I need? Estimate the volume you need in cubic yards (using the length, width, and depth of the area) and then convert it to tons. Recycled asphalt typically weighs around 1.2 to 1.4 tons per cubic yard.
