The optimal aggregate selection for a stable driveway surface emphasizes minimal displacement under vehicular and pedestrian traffic. This characteristic is achieved by employing materials with specific angularity, size gradation, and compaction properties. An example is crushed stone with a high degree of interlocking, which resists lateral movement more effectively than rounded gravel.
A stable driveway minimizes maintenance, reduces dust generation, and enhances safety by providing a firm, predictable surface. Historically, gravel driveways have been a cost-effective surfacing solution; however, material selection significantly impacts long-term performance and longevity. The benefit of choosing appropriately is a significantly reduced need for regrading and replenishment.
