Asphalt Parking Lot Thickness
Let s briefly speak on asphalt resurfacing methods.
Asphalt parking lot thickness. Butt joints are areas where old asphalt or concrete meets new asphalt pavement. By focusing on the thickness of the asphalt driveway it can help provide longevity. Layers of asphalt asphalt is comprised of several layers of different materials. As such asphalt paving contractors must find a way to smooth the transition from old surface to new.
This will ultimately raise the property value of a home. For businesses and commuter lots the design must consider the use of the pavement by buses trucks and other heavy vehicles. 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. The thing is asphalt driveways should always be built to accommodate the traffic load.
On top of the base we typically recommend applying two 1 5 layers of asphalt. The thickness of a parking lot depends heavily on the amount and type of traffic of that specific lot. After paving the two layers are compacted to a thickness of 4 to form the final thickness. For full depth heavy duty parking lots he recommends 7 5 inches of hot mix asphalt on subgrade.
Most parking lots are built with a foundation of native substrate soils which vary in thickness. Several factors go into that answer so let s take a look at how we determine parking lot thickness which begins by understanding the layers used to comprise asphalt. Minimum pavement thickness designs are given for various size parking lots heavily loaded ar eas and industrial parking lots. When resurfacing existing pavement the asphalt covering should be 2 inches thick.
For full depth light duty commercial parking lots murphy recommends 4 5 inches compacted thickness of hot mix asphalt on the subgrade. The parking area is the first part of a building complex seen by the user. For standard commercial jobs the dense graded aggregate layer is typically about 8 thick. It is very rare to install an asphalt surface that does not connect to existing driveways roadways or parking lots.
Please note the primary objective of parking lot design is to provide safe efficient vehicular access to parking stalls that serve businesses commuter lots and residential facilities. 5 2 parking lot design the information in this chapter will provide a general guide to proper parking area design construction and facility layout. Instead it seems 6 inches is the standard asphalt driveway thickness in the case of a commercial parking lot. Busy parking lots like the ones at supermarkets and big box stores are paved in the same way with two lifts residential driveways on the other hand are used only by small numbers of vehicles traveling at slow speeds.
