Road Grading

Road Grading

Road Grading consists of using a motor grader (aka “road” grader) to restore the driving surface and drainage attributes of 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.

Motorists should exercise extreme caution when driving in the area of a grading operation. Be patient, stay behind the grader and do not cross over the gravel windrow that may be present. Operators will move out of the way only when it is safe to do so.

Q: How does the Metro District determine which roads will be graded, and when?

A:  There are some 400 miles of roadways within the Metro District’s area of responsibility. Roads are continually evaluated by Roads and Streets crews to determine which roads will be graded. Factors such as volume of daily traffic using the road, average speed of traffic, amount of heavy truck traffic, among others, are all factors in determining when and where the grading resources will be deployed. Citizen input is also considered. Citizens can place information into the community inquiry system on the Pueblo West Metro District website, and while this cannot guarantee a service response, it will generate the Streets and Roads condition to do a visual inspection of the issue, and place the issue onto a priority based list.

Q:  What is a windrow in motor grading terminology?

A:  A windrow is a conical ridge, or a long narrow accumulation of gravel material placed by the grader while maintaining a gravel road. The purpose of this wind row of material is to scrape dips, divots and holes out of the road, and to re-smooth material thereby filling in washboard sections, dips, and divots. Grading in this manner should be followed up with wheel compaction with a mechanically driven compactor. You should not try to cross over the wind row of material, or your vehicle could be damaged. The grader operator is constantly watching the mirrors and is aware of your presence. The operator will pull over and let you pass when it is safe to do so.
