Asphalt Parking Lot Thickness

Layers of asphalt asphalt is comprised of several layers of different materials.

Asphalt parking lot 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. When resurfacing existing pavement the asphalt covering should be 2 inches thick. In addition this chapter gives comparable designs for both full. For businesses and commuter lots the design must consider the use of the pavement by buses trucks and other heavy vehicles.

For full depth light duty commercial parking lots murphy recommends 4 5 inches compacted thickness of hot mix asphalt on the subgrade. As such asphalt paving contractors must find a way to smooth the transition from old surface to new. It is very rare to install an asphalt surface that does not connect to existing driveways roadways or parking lots. Most parking lots are built with a foundation of native substrate soils which vary in thickness.

This will ultimately raise the property value of a home. 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. 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.

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. For standard commercial jobs the dense graded aggregate layer is typically about 8 thick. It is the gateway through which all customers. Instead it seems 6 inches is the standard asphalt driveway thickness in the case of a commercial parking lot.

Is 2 inches of asphalt enough for a driveway in the case of a commercial establishment. Minimum pavement thickness designs are given for various size parking lots heavily loaded ar eas and industrial parking lots. The thickness of a parking lot depends heavily on the amount and type of traffic of that specific lot. The parking area is the first part of a building complex seen by the user.

By focusing on the thickness of the asphalt driveway it can help provide longevity. Let s briefly speak on asphalt resurfacing methods. 5 2 parking lot design the information in this chapter will provide a general guide to proper parking area design construction and facility layout. On top of the base we typically recommend applying two 1 5 layers of asphalt.
