What is a gravel road grading?
Road grading consists of using a motor grader to restore the driving surface and drainage attributes to roads. The operator will remove washboards, potholes and other irregularities by cutting the surface of the road or filling them with material moved back and forth across the road with the road grader.
How long do gravel roads last?
How Long Will a Gravel Driveway Last?
With proper care and maintenance, a gravel driveway can last up to 100 years. The beauty of gravel is that it can be repaired and replenished on an ongoing basis.
How do you stabilize a gravel road?
The best long-term solution for driveway stabilization includes digging down 8 to 12 inches below the surface of the driveway, removing all roots and plant material, and thoroughly compacting the soil with a plate compactor or roller. On top of this compacted sub-grade layer, put down a 4-inch layer of coarse gravel.
How do you scrape a gravel road?
Leave the tines in the ?up? position and just use the blade on the bottom to scrape the surface. Depending on the width of your scraper and your road, you simply run up/down the road until the entire surface has been scraped.

Why do gravel roads fail in heavy traffic?
Unfortunately, most gravel roads will fail when exposed to heavy hauls even when shaped properly.This is due to weak subgrade strength and marginal gravel depths which are often problems with gravel roads.The low volume of normal traffic does not warrant recon- struction to a higher standard.
What should the angle of moldboard be when grading gravel?
When grading a gravel road, the ideal horizontal angle for the moldboard is between 30 and 45 degrees. This gives you the best control over the loose aggregate and makes sure it doesn?t spill around the leading edge of the moldboard. The pitch of the moldboard is the angle that the blade edge touches the road surface at.
