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]
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 ...
Permeable paving systems, especially those with porous surfaces, require maintenance in order to keep the pores clear of fine aggregates as to not hinder the systems ability to infiltrate stormwater. The frequency of cleaning is again dependent on many site specific factors, such as runoff volume, neighboring sites and climate.
Add an inch or so of pea gravel (tiny round river pebbles) on top of the compacted limestone, and then lay the stones out on the pea gravel. Space them for a normal stride, so that an average ...
The decision whether to pave a gravel road or not often hinges on traffic volume. It has been found that maintenance costs for gravel roads often exceed the maintenance costs for paved or surface-treated roads when traffic volumes exceed 200 vehicles per day.

Water content is an important parameter that could change the angle of repose. Reportedly, a higher water content can stabilize a slope and increase the angle of repose. [5] However, water saturation can result in a decrease in the slope's stability since it acts as a lubricant and creates a detachment where mass wasting can occur. [6]
Jul. 19—MASONTOWN — Residents of Burke Road will have no relief until this fall, said Jennifer J. Dooley, West Virginia Department of Transportation public relations director. Dooley said she ...
Infiltration galleries may be used to supplement a storm sewer, by directing storm runoff from non-road areas.. While the catchbasins under sewer grates work well on swift-flowing surfaces like asphalt and concrete, heavy storm water flow on grass lawns or other open areas will pool in low areas if there is no outlet.
