What is the spread rate for the chip spreader?

The spread rate for a chip spreader is crucial for ensuring that the right amount of asphalt binder is applied evenly across the surface before chips are placed. A spread rate of 0.26 to 0.33 ft/syd is considered optimal for most applications involving chip seal operations. This range allows for effective adhesion of the aggregate to the asphalt while also minimizing wastage and ensuring that the surface provides the intended texture and grip for vehicles.

Applying within this spread rate ensures that the asphalt binder is neither over-applied, which could lead to bleeding or excessive runoff, nor under-applied, which may result in inadequate bonding of the chips and potential surface failure. Thus, the specified range supports the overall performance and durability of the asphalt surface.
