Unpaved Roads, Car Parks and Windfarm Access Routes

Any temporary or permanent unpaved surface subject to trafficking needs a correctly engineered, but cost-efficient design, especially when considering weak subgrade conditions. This approach ensures optimal use of resources and provides a reasonably smooth surface, with tire loads distributed evenly to avoid rutting and meet the required design expectancy and lifetime.

    Project Geometry and Loading





    Vehicle type

    Number of visits

    Typical cars [w ≈ 10kN (≈ 1 tonne)]

    Light construction vehicles [w ≈ 50kN (≈ 5 tonnes)]

    Fully loaded vans [w ≈ 25kN (≈ 2.5 tonnes)]

    Typical lorries [w ≈ 80kN (≈ 8 tonnes)]

    Heavy tippers and lorries [w ≈ 120kN (≈ 12 tonnes)]





    Note: For construction purposes, we will consider a typical 20t truck (max axle load 97.5kN) in our assessment.
