In highway work, grade is usually given in terms of?

In highway work, grade typically refers to the slope or steepness of the road, and this is most commonly expressed as a percentage. The grade, or slope, is calculated by taking the vertical rise of the road divided by the horizontal run and multiplying by 100 to convert it into a percentage. This provides an easy way to understand how steep the road will be, which is essential for design, safety, and drainage considerations.

Using percent grades in highway work allows engineers and surveyors to communicate slope information clearly and effectively, ensuring that the roadway design meets safety standards and is suitable for vehicular traffic. Percentages are a standard convention in civil engineering because they are straightforward to understand and apply in calculations related to road design and construction.
