What causes potholes on dirt roads?
Water is the biggest contributor to the deterioration of unpaved roads. Regardless whether it seeps in from above or below, water simply destroys roads. Besides rutting and eroding away an unsealed road surface, water causes the development of potholes.
How do you fill holes in dirt roads?
Start by filling the pothole with coarse gravel up to about three inches below the surface of the driveway. Next you should compact the coarse gravel using a steel tamper or a 4×4 wooden post. For a dirt driveway, fill the hole with dirt up to three to four inches above the desired surface level.
What factors lead to potholes?
Potholes are caused by the expansion and contraction of water after it has entered into the ground under the pavement. As the weight of cars and trucks pass over the weak spot in the road, pieces of the pavement weaken, which causes the material to break down from the weight, creating the pothole.
Why do potholes keep coming back?
One major factor is the freeze-thaw cycle. Water gets into cracks in the pavement, whether that pavement is new or old. That water freezes, then expands those cracks, creating a hole. Cars driving over those filled holes causes the hole to grow and furthers the crumbling.
How do you fix a muddy dirt road?
