Erosion surface

Just like mountains and rocks, erosion can also occur on unsealed roads due to natural and anthropogenic factors.

During winter, snow cover slows down erosion rate by preventing direct contact between the raindrop and the road surface.

[4] In addition to natural factors, high traffic volume can also speed up the road erosion rates.

The friction caused by moving vehicles could potentially lead to crushing and abrasion, thus break down the coarse particles on the road surface.

[6] While laser scanning requires many specialist and expensive equipment, repeat photography and digital photogrammetry can also be used to obtain data for researchers with a much smaller budget.
