ROAD GRADE AND ALIGNMENT STANDARDS Clause Samples
The 'Road Grade and Alignment Standards' clause sets the required specifications for the slope (grade) and layout (alignment) of roads constructed under the agreement. It typically details acceptable maximum and minimum grades, curvature, and other geometric requirements to ensure roads are safe and suitable for their intended use. By establishing these standards, the clause ensures that all road construction meets safety, accessibility, and regulatory requirements, thereby preventing disputes and reducing the risk of substandard or unsafe roadways.
ROAD GRADE AND ALIGNMENT STANDARDS. Purchaser shall follow these standards for road grade and alignment except as designed: Grade and alignment must have smooth continuity, without abrupt changes in direction. Maximum grades may not exceed 18 percent favorable and 12 percent adverse. Minimum curve radius is 60 feet at centerline. Maximum grade change for sag vertical curves is 5% in 100 feet. Maximum grade change for crest vertical curves is 4% in 100 feet.

ROAD GRADE AND ALIGNMENT STANDARDS. Purchaser shall follow these standards for road grade and alignment. ▪ Grade and alignment must have smooth continuity, without abrupt changes in direction. ▪ Maximum grades may not exceed 18 percent favorable and 12 percent adverse. ▪ Minimum curve radius is 60 feet at centerline. ▪ Maximum grade change for sag vertical curves is 8% in 100 feet. ▪ Maximum grade change for crest vertical curves is 6% in 100 feet. Grade limitations and alignment are modified as follows: Road Stations Maximum Grade (%) Favorable Adverse Purchaser shall construct excavation slopes no steeper than shown on the following table: Material Type Excavation Slope Ratio Excavation Slope Percent Common Earth (on side slopes up to 55%) 1:1 100 Fractured or loose rock ½:1 200 Hardpan or solid rock ¼:1 400 Purchaser shall construct embankment slopes no steeper than shown on the following table: Material Type Embankment Slope Ratio Embankment Slope Percent ▇▇▇▇▇ Soils 2:1 50 Common Earth and Rounded Gravel 1½:1 67 Angular Rock 1¼:1 80 Purchaser shall construct excavation and embankment slopes to a uniform line and left rough for easier revegetation.
