Maintenance of a gravel road in Denmark. Gravel roads require much more frequent maintenance than paved roads, especially after wet periods and when accommodating increased traffic. Wheel motion shoves material to the outside (as well as in-between travelled lanes), leading to rutting, reduced water-runoff, and eventual road destruction if ...
Washboarding effect on a road. Washboarding or corrugation [1] is the formation of periodic, transverse ripples in the surface of gravel and dirt roads.Washboarding occurs in dry, granular road material [2] with repeated traffic, traveling at speeds above 8.0 kilometres per hour (5 mph). [3]
A grader, also commonly referred to as a road grader, motor grader, or simply blade, is a form of heavy equipment with a long blade used to create a flat surface during grading. Although the earliest models were towed behind horses, and later tractors , most modern graders are self-propelled and thus technically "motor graders".
Chip seal products can be installed over gravel roads to eliminate the cost of grading, road roughness, dust, mud, and the cost of adding gravel lost from grading. Adding chip seal over gravel is about 25% of the price of resurfacing with asphalt, $170,000 for a 4-mile project done in Minnesota [6] compared to $760,000 had it been redone with ...

When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. [1]
As a road stabilizer, magnesium chloride binds gravel and clay particles to keep them from leaving the road. The water-absorbing (hygroscopic) characteristics of magnesium chloride prevent the road from drying out, which keeps gravel on the ground. The road remains continually "wet" as if a water truck had just sprayed the road. [26]
