    Therefore FL numbers are only specified on elevated slabs when measurements are taken before shores and forms are removed and the slab has no camber. Figures B-5 and B-6 are examples of complete apron layouts with tie-downs, parking areas, taxilanes, and taxiways. If your apron is a Group I apron, then you are finished determining the depth. See a complete description of joints. Why Asphalt is a Good Paving Choice in Wisconsin When deciding between a concrete and an asphalt parking lot, one of the most important things to consider is the climate where the project is located.

    Smaller coarse aggregates will require additional water in concrete and should be avoided if possible. Get more in-depth information about concrete in our Concrete resource page. If it is a parking garage project, for instance, a satisfactory as-built broom-finished surface for another parking garage should be chosen as a sample. Changing weather and temperatures cause more damage and deterioration in concrete surfaces. Required consistency of the concrete will depend on construction methods. Specifiers must recognize this inherent difficulty with different-sized concrete placements and owners must realize that while the larger parking garage placements cost less and shorten the schedule, they will not have the same appearance, flatness, texture, and drainage as a sidewalk.

    Slipforming necessarily limits the amount of water that can be used in mix and the slipform process requires cementitious materials and aggregate combinations that will produce smooth surfaces without handwork for closing voids. Elevation differences are measured every feet within 72 hours after the concrete is placed and those measurements are entered into a calculation to determine floor levelness FL. This pavement drains to a low trough that discharges to a drainage structure at the edge. The long term trade off, however, is asphalt parking lots require more ongoing maintenance than that of concrete parking lots.

Suggested specifications for concrete parking areas. book

A concrete parking lot is really nothing more than an exterior slab on ground or slab on grade. Parking lots include slabs, joints, curbs, light poles, and drainage facilities — and all of these need to work together.

Unlike asphalt, concrete is not pliable, making it much less forgiving when it comes to heaving from freeze and thaw cycles. If it is a parking garage project, for instance, a satisfactory as-built broom-finished surface for another parking garage should be chosen as a sample.

Specifiers must recognize this inherent difficulty with different-sized concrete placements and owners must realize that while the larger parking garage placements cost less and shorten the schedule, they will not have the same appearance, flatness, texture, and drainage as a sidewalk.

Sealing the cracks will help to prevent further damage and failures like alligatoring and even potholes by preventing or minimizing the amount of water entering into them. Concrete parking lots can also be installed in a large variety of colors or, if you have an existing parking lot, it can be stained a variety of different colors as well.

Over its lifetime, the most expensive pavement is a typical asphalt pavement which is cheaper to build initially, but is under-designed in load-carrying capacity and ends up with high maintenance costs. The loads are mostly static or low speedso flatness and smoothness are not as critical as for streets and highways.

The contractor does not know the concrete mixture proportions, setting time, or bleeding rate and duration. The use of standard specifications of the local transportation agency can be advantageous where materials suppliers are familiar with them and routinely deliver quality concrete to meet them.

Contractors can achieve many different specified broom finish characteristics, but the most important issue often affecting achievability is the size effect. The results of brooming in one pass while standing on the placement perimeter differ dramatically from those for large-scale concrete placements.

Better For the Environment: Asphalt is considered a green technology because it can be recycled: A parking lot contractor in Madison can grind up an old asphalt parking lot to be reused. In these conditions, dark asphalt pavement can become extremely hot, while the lighter color of a concrete parking lot results in a lower temperature during the summer.

To right size the apron, the depth of the parking position must be determined. However, only a quality commercial grade concrete sealer is recommended and should only be applied by a reputable sealing contractor.

The pavement designer can use this nomograph and an iterative technique to come up with the pavement thickness based on the subbase strength and the anticipated loads. The concrete must be air entrained and have a high quality cementitious paste to survive many freeze-thaw cycles and applications of deicer salts.

With the introduction of high-stacking, narrow-aisle warehouses in the s it became more important to have concrete floors that were much flatter than in the past.

GUIDE FOR DESIGN AND CONSTRUCTION OF CONCRETE PARKING LOTS

The Top 3 Benefits of Choosing An Asphalt Parking Lot Quick Installation, Lower Cost: An asphalt driveway or parking lot can usually be laid just a few days, depending on the size of the project, which can save you money. In any case, concrete should be placed with the lowest amount of water that will provide workability and finishability.

Standard Details and Specifications

In areas with severe exposure, specifications may require a day compressive strength of at least 4,psi for durability.

Wolf Paving offers professional paving services from Milwaukee to Madisonand everywhere in between, including all areas around: Sun Prairie, Oconomowoc and Waukesha. An asphalt parking lot will soften in extreme heat and become oily. A sidewalk has nearly the same ease-of-placement benefits as a mockup.

This is a better reference than a small sample panel, but is still not indicative of what can be achieved for a large-scale concrete placement in a parking garage.

Concrete Parking Lots

Less Maintenance: A concrete parking lot has a long lifespan and is relatively low maintenance, needing only joint sealing and an annual cleaning. In addition, the dark color of asphalt pavement that can cause problems in the heat actually solves problems in the cold - it absorbs more heat from the sun, causing snow and ice to melt much more quickly.

They primarily accommodate parked vehicles, but may also provide maneuvering areas and access for delivery vehicles. Binding: Paperback Publisher: ACI Concrete parking lots serve many kinds of public facilities, commercial developments, businesses, and multifamily housing projects.

What type of ongoing maintenance does a concrete parking lot require compared to the other types of parking lots? For bigger delivery trucks, the pavement will need to be 5 or 6 inches thick. In addition, it is helpful for architects and owners to visualize how wavy or bumpy different FF values are.

These depths are only a recommendation for planning purposes.Parking lots are a cost effective alternative to asphalt that saves owners money in lifetime costs. To encourage good construction of concrete parking lots, the American Concrete Institute (ACI) formed CommitteeParking Lots, in ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates.

Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
