The condition of the gravel roads is in the Finnish system described on the basis of the service level and the frost damage. The service level describes the gravel road surface condition, and is evaluated on a scale of 1 to 5 (best) for each sub factor: road surface smoothness, density and dustiness.
Rolling dips should be dug 3 to 6 inches deep at an angle of 45 to 60 degrees from the centerline of the road. Lanoie recommends replacing the removed dirt or material with crushed angular stone, then adding road surfacing gravel mix atop that. If your road is in very bad shape, you may be forced to consider rebuilding it, at least in part.

The quantities of calcium chloride recommended for ap plication on roads having one-half to one inch of loose gravel on the surface are: First application—1 pound per square yard. Second application— 1/2 pound per square yard. For fairly heavy traffic, a third application of one-half pound per square yard is usually required.
This manual was developed with a major emphasis on the maintenance of gravel surfaced roads, including some basic design elements. Gravel roads are often considered to provide lower quality service than paved road surfaces. Yet, in many rural regions, the volume of traffic is so low that paving and maintaining a paved road is not economically ...

Here are six types of road maintenance that can be used for each job. 1. Asphalt Overlays. Asphalt overlays restore roads to a smooth condition. This resurfacing uses the deteriorating asphalt as a base for which the new layer is added on top of, instead of tearing up the worsening one. 2. Patching. Patching is the process of filling potholes ...
