9 Tips for Choosing the Right Road Plates

On a construction site, road plates provide a

suitable solution to the challenges posed by the terrain, whether for construction work, a temporary project, or the protection of specific areas. Also known as construction site plates, they facilitate the movement of machinery while reducing the risk of soil damage. They protect surfaces subject to frequent traffic from vehicles and heavy equipment.

To select the right solution for your construction sites, check out these 9 tips from Altec France to help you choose the right road plates.

Define Your Needs Precisely

The choice of a road plate depends primarily on the characteristics of your construction site. Several criteria must be taken into account to identify the most suitable solution:

The type of work being performed
The duration of the project
The number and frequency of vehicle passes

For example:

A short-term project lasting a few days → choose a lightweight solution that is easy to install and move.
A long-term project with regular traffic → opt for slabs designed to withstand heavy use.

The greater the demands of the project, the more the traffic slab must offer appropriate strength and durability.

Selecting the Right Traffic Mat for the Type of Vehicle

When selecting a traffic mat, you must consider the vehicles that will be traveling on the job site and their loads. A traffic mat whose capacity does not match the weight of the equipment may deform or deteriorate under repeated traffic. Proper sizing thus helps minimize risks and protect traffic surfaces.

It is also essential to evaluate several factors before selecting your road plate:

The total weight of the loaded vehicle, including any materials or equipment being transported
Traffic intensity, depending on whether vehicle passes are occasional or regular
Soil characteristics, including moisture content, slope, and soil stability

Consider the Nature of the Ground

The nature of the ground is an important factor in selecting construction mats. Each surface presents specific challenges that require an appropriate solution.

• Loose soil: mud, sand, dirt

→ Choose wide, thick mats

→ Distribute the weight of the equipment over a larger area

→ Minimize sinking and damage to the ground

• Green spaces: lawns and landscaped areas

→ Choose HDPE (high-density polyethylene) mats

→ Opt for a flexible material that minimizes damage to vegetated surfaces

→ Preserve lawns and landscaping

• Roadways and hard surfaces: concrete, asphalt, and paved surfaces

→ Use mats with a non-slip surface

→ improve vehicle traction

→ reduce the risk of damage to road surfaces

• Sloped or uneven terrain

→ prioritize panels that offer optimal traction

→ install fastening systems to keep the panels in place and ensure safe traffic flow.

Choosing the Size of Your Construction Site Pavers

Common sizes are 1 × 2 m and 2 × 3 m, but the size should be chosen based on site conditions and anticipated traffic.

• Large-format pavers

→ cover a larger area

→ reduce the number of joints between pavers

→ are suitable for areas with heavy equipment traffic

• Small slabs

→ easier to transport and handle

→ facilitate installation in hard-to-reach areas

→ particularly well-suited for narrow passages or confined spaces

To determine the most appropriate size, consider the available space, access conditions, and the volume of traffic on the construction site.

Choosing the Right Thickness for Roll-Off Plates

The thickness of a roll-off plate must be appropriate for the weight of the vehicles and the frequency of their passage.

10 to 15 mm: suitable for light use and occasional traffic

• 15 to 30 mm: suitable for regular use, offering a good balance between strength and ease of handling

• 30 mm and above: recommended for heavy loads and areas subject to heavy traffic

Insufficient thickness can reduce the effectiveness of the plate and lead to:

• Deformation under the weight of vehicles

• Lack of stability during passage

• Insufficient protection of the ground

The choice of thickness must therefore be based on the weight of the vehicles, the frequency of traffic, and the characteristics of the terrain.

Check the load capacity of your plates

The load capacity of a traffic plate must match the weight of the vehicles that will be traveling on the job site. Each model has a load limit that must be observed.

• 10 to 20 metric tons → suitable for moderate use

• 20 to 50 metric tons → recommended for heavy traffic

• 50 metric tons and above → intended for job sites subject to heavy loads

Always allow for a safety margin between the plate’s maximum load capacity and the actual weight of the equipment.

An undersized plate can result in:

• Risks to equipment and operators

• Soil degradation

• Additional costs related to damage or replacement of equipment.

Choosing the Right Material

HDPE (high-density polyethylene) stands out for its light weight and ease of handling. It is particularly well-suited for green spaces and sensitive areas, as it facilitates the movement of equipment while minimizing the risk of soil damage.

Planning for Installation and Logistics

A rolling plate must also be easy and convenient to use on the job site. Built-in handles make it easy to handle and position, while a non-slip surface improves traction for machinery. The ability to connect the plates together also allows for the creation of a stable, continuous traffic surface. These features help reduce installation time, simplify setup, and ensure safe movement of machinery.

Buying or Renting Road Plates: Which Option Should You Choose?

The choice between buying and renting road plates depends on the frequency and duration of your projects. Renting is particularly well-suited for one-time jobs, offering a cost-effective solution for a short period without requiring a significant investment. Conversely, buying becomes more advantageous for regular use, as it gives teams greater autonomy and ensures the equipment is available for every job.
