    Concrete is widely used in the land development sector of civil engineering.  A brand new residential or commercial subdivision includes many components that will involve concrete, but the component that is concentrated on in this section of the website is parking lots.  Parking lots are abundantly found throughout the world, and there are two main materials that parking lots are made out of, either cement concrete or asphalt concrete.  According to ACI 330R, cement concrete pavements have many advantages over asphalt pavements.  These include:

  • Loads are spread over larger areas of the subgrade compared with asphaltic pavements.

  • Thinner concrete pavements can be used for the same subgrade material.

  • Concrete surfaces resist deformation from maneuvering vehicles.

  • Concrete surfaces drain well on relatively flat slopes.

  • Concrete has relatively simple maintenance requirements.

  • Traffic-lane and parking stall markings can be incorporated into the jointing pattern.

  • Concrete is not adversely affected by leaking petroleum products.

  • The light-reflective surface of concrete can be efficiently illuminated with minimal energy requirements and can help reduce summertime surface temperatures.

  • Concrete parking lots reduce the impacts of the urban heat island effect by providing a cooler urban environment and reducing ozone protection.

    Much consideration goes into the design and construction of these concrete parking lots.  This section of the web page will describe the process of design and construction, and also drainage characteristics and new technologies that are found in the field.  Below is a further summary of the different pages located in this section of Concrete in Society.

Summary of Pages

Design of Concrete Parking Lots- This page describes the properties that determine how thick the concrete must be in a parking lot, the types of subgrade, and how these properties are related to determine the thickness.  Also, this page describes the different types of joints that are used in the construction of concrete parking lots and what purpose each one serves.

Construction - This page describes processes in construction of a concrete parking lot, and atmospheric conditions which can affect a paving schedule.

Drainage- This page describes drainage characteristics in concrete parking lots.  Also, a recent technology that is being used more often, pervious concrete is discussed along with its role in water drainage.

Links- This page lists many links that contain further information about land development and concrete pavements in general.
