447:— the formation of corrugations across the surface at right angles to the direction of travel. Narrow-spaced washboarding can develop on gravel roads due to inconsistent moisture levels in the gravel, poor quality gravel, and vehicular stress to the road. Washboarding can also occur when graders exceed recommended speeds during the construction or maintenance phase causing the blade to bounce on the surface creating a pattern of widely-spaced corrugations. Corrugations from washboarding can become severe enough to cause vibration in vehicles so that bolts loosen or cracks form in components. Proper grading is needed to remove the corrugations, and reconstruction with careful choice of good quality gravel can help prevent them reforming. Additionally, installing a

Construction of the road surface is done gradually through multiple applications of layers of gravel, with compaction prior to the addition of the following layer.

Gravel roads require much more frequent maintenance than paved roads, especially after wet periods and when accommodating increased traffic.

Although well-constructed and graded gravel roads are suitable for speeds of up to 100 km/h (60 mph), driving on them requires far more attention to variations of the surface, and it is easier to lose control than on a paved road. In addition to potholes, ruts and loose stony or sandy
