Good gravel road maintenance or rehabilitation depends on two basic principles: proper use of a motorgrader (or other grading device) and use of good surface gravel The use of the grader to properly shape the road is obvious to almost everyone, but the quality and volume of gravel needed is not as well understoodIt seems that most gravel.

Gravel road

A gravel road is a type of unpaved road surfaced with gravel that has been brought to the site from a quarry or stream bedThey are common in less-developed nations, and also in the rural areas of developed nations such as Canada and the United StatIn New Zealand, and other Commonwealth countries, they may be known as 'metal roads' They may be referred to as 'dirt roads' in common.

Geometric design of roads

The alignment is the route of the road, defined as a series of horizontal tangents and curv The profile is the vertical aspect of the road, including crest and sag curves, and the straight grade lines connecting them The cross section shows the position and number of vehicle and bicycle lanes and sidewalks, along with their cross slope or.

Cross Slope

Cross Slope Pavement cross slope is an important cross-sectional design element The cross slope drains water from the roadway laterally and helps minimize ponding of water on the pavement This prevents maintenance problems and also minimizes icing from occurring on poorly drained pavement.

Safe Driving on Gravel Roads

We must equip ourselves with the knowledge and skills required to adjust our driving behaviour when moving away from tarred roads to gravel roads What is Gravel Road? To consider safe driving techniques on gravel roads we need to start with a better understanding of the nature of gravel roads Gravel is small, broken-down rock material.

Superelevation

A design exception is also required if a superelevation rate is proposed that is different from the published rate per the State’s policy for that curve, regardless of whether the curve is a controlling one (minimum radius for a design speed) or not Note that no design exception is required for superelevation transition lengths.
