Building a Durable Gravel Driveway in Alaska

For a gravel driveway that withstands spring breakup, use a geotextile driveway fabric over the subgrade to separate gravel from wet clay. Choose a non-woven fabric with high tensile strength. Layer 3-4 inches of crushed gravel (3/4-inch minus) over the fabric and compact with a vibrating plate compactor. Crown the center slightly (1/4 inch per foot) for drainage. Railroad ties for edging are optional; investing in proper grading and compaction yields better long-term results. Recycled concrete is a cost-effective alternative. Ensure the fabric extends beyond the driveway edges to prevent migration.
