Why are some rural roads not so good?
As a practical matter, many rural roads are not con- structed in this way but consist entirely of native materials encountered during grading. This can be a factor contributing to poor performance. All roads must incorporate features to drain water off the road surface and allow it to cross from one side to the other.
What are the steps in the construction of a road?
20. Construction Steps • Clearing & Grubbing: It includes removing any unwanted material i.e. tree roots, grass, loose soil, Preparing the leveled surface • Stripping off the top of soil to avoid the plant growth on the road.
How is the construction of an earthen road?
Construction Procedure for Earthen Road • Preparation of Sub-Grade: Arranging sub-grade in proper gradient & camber. • The sub-grade is rolled & watered to have OMC & compacted to MDD. • Over it, a layer of soil 10cm thick is sprayed, rolled, & finished to have required camber & gradient. • 4-5 days curing. • Opening to traffic.
Why are unpaved roads bad for the environment?
Rural roads are a major source of sediment that ends up in stream channels (fig. 2). This is especially true for unpaved roads located near streams that are used year-round. Sediment delivered to streams from roads causes streams to run muddy and take a long time to clear after storms.
What’s the best way to avoid road construction?
We’ve got some tips to help you avoid road construction. Ask the area highway patrol if they have a special radio frequency you can tune into to hear the latest traffic or construction reports. Look at the state’s Department of Transportation for websites that will alert you to construction areas and problematic traffic spots.

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.
