This 2018 asphalt parking lot design guide has been prepared to assist readers in understanding all phases of asphalt parking lot design including planning construction and maintenance.

For businesses and commuter lots the design must consider the use of the pavement by buses trucks and other heavy vehicles. Minimum pavement thickness designs are given for various size parking lots heavily loaded ar eas and industrial parking lots. After paving the two layers are compacted to a thickness of 4 to form the final thickness. By focusing on the thickness of the asphalt driveway it can help provide longevity.

As such asphalt paving contractors must find a way to smooth the transition from old surface to new. For standard commercial jobs the dense graded aggregate layer is typically about 8 thick. Butt joints are areas where old asphalt or concrete meets new asphalt pavement. When resurfacing existing pavement the asphalt covering should be 2 inches thick.
