Ground Protection
In addition to temporary roadways, site access also includes stable work areas such as laydown or staging zones. Understanding how each area will be used is the first step in selecting the right approach.
Site access requirements are determined by understanding and evaluating the equipment, the ground and the duration. Different types of equipment impose loads in different ways.
Wheeled equipment concentrates weight on smaller contact areas, creating higher point loads that must be accounted for. Tracked equipment distributes weight over a larger area, reducing ground pressure. However, it introduces lateral forces when turning that can shift or displace materials if the surface is not stable or properly connected.
Ground conditions must be evaluated to determine how those loads are supported. Soil composition, compaction and moisture content all influence product selection. Surfaces that appear stable may not remain that way once equipment is introduced or environmental conditions change. Rain, freeze-thaw cycles and heavy travel can quickly alter ground conditions, reducing its ability to support loads.
In addition to the equipment being used and the ground conditions, the duration of the job needs to be considered. Longer duration jobs with heavier travel will typically require larger access mats.
Applying Principles
With those variables understood, site access decisions can be applied to specific areas of the jobsite.
Access routes must support repeated equipment movement across varying terrain and conditions. These routes are subject to dynamic loading, changing weather and frequent use. The surface must remain stable and consistent to allow equipment to move safely and efficiently without becoming stuck or unstable.
Stable work areas are where equipment operates. These areas must provide a level and predictable surface that allows operators to maintain control and operate within equipment tolerances. Any movement or inconsistency in the surface can affect stability and performance. Even minor changes in the supporting surface can result in shifting or uneven load distribution, which may
Ground protection mats are typically used to minimize surface damage when working in established residential and commercial sites. They are usually smaller, lighter and deployed by hand.
