Concrete parking lots are a potentially lucrative market for concrete contractors and make good economic sense for building owners. Today, about 90% of parking lots are paved with asphalt, but improved equipment and rising prices of asphalt have made concrete more competitive.A concrete parking lot is really nothing more than an exterior slab on ground (or slab on grade). Perhaps what defines it as a parking lot, and what makes it a little different to design and build, is the sloped surface for drainage, the ability to handle heavy vehicular loads, and severe environmental exposure.
how to design and build concrete parking lots and also why concrete parking lots are preferable to asphalt.
An important consideration is that there's more to the parking lot than just pavement. Parking lots include slabs, joints, curbs, light poles, and drainage facilities — and all of these need to work together. Parking lots are typically placed directly on the existing soil rather than on a compressed subgrade.
The important thing is to get the compaction of the subgrade uniform so that some areas don't sink and crack the pavement. Find more information on subbases and subgrades.
