In Texas, we have more than 1,300 different types of soils, all of which react uniquely to environmental conditions. In order to determine the proper pavement types used for development, whether it be neighborhood streets or restaurant parking lots, a geotech report is needed.
In this detailed engineering report, we find a wide range of conditions pertaining to the land. For pavement recommendations, some key factors include type of soil, moister content, and subsurface geological features.With this report and its determinations, pavement surfaces can be constructed.
The next figure illustrates section views of what the geotech might recommend to insure strength and durability for concrete and asphalt.
There are key differences between concrete and asphalt pavement. First, asphalt is a flexible pavement, which is commonly used for the roads we drive on. It is relatively inexpensive and has a quick curing time. However, asphalt requires regular maintenance in order to keep its structural integrity.

Concrete is a rigid pavement, typically found in driveways, parking lots, and other locations requiring more strength and durability. The time and effort that goes into paving with concrete increases the cost considerably. A concrete parking lot can provide a lasting surface that also drains well.
