The amount of cushion sand required for a 1-mile stretch of road will vary depending on several factors such as the width of the road, the depth of the base layer, and the compaction requirements. Generally, a minimum of 6 inches of cushion sand is used as the base layer for road construction.

It is important to note that the depth of the cushion sand layer will depend on several factors such as the soil conditions, the expected traffic volume, and the climate conditions. More cushion sand will be required in areas with heavy traffic or poor soil conditions, while less will be required in areas with light traffic or good soil conditions.

It’s difficult to give an exact amount of cushion sand needed for 1 mile of road, as it will depend on the specific project, however, as a rough estimate it could be around 10,000 – 15,000 cubic yards (7,645 – 11,467 cubic meters) for a 1-mile stretch of road, considering the cushion sand layer is 6 inches deep.

It’s always better to consult a professional or a construction engineer to determine the exact amount of cushion sand required for your specific project, taking into consideration all the factors that affect the road construction.
