Quick Answer
Gravel driveways require regular maintenance to extend their lifespan. Proper maintenance practices include raking the gravel surface, filling potholes, and applying a stabilizing agent.
Regular Raking and Grading
Rake the gravel surface at least once a month to redistribute the aggregate material and prevent it from becoming compacted. Use a box blade or a skid-steer loader with a grading attachment to maintain an even surface and smooth out any imperfections. For optimal performance, maintain a 2-3 inch layer of gravel on top of the driveway.
Filling Potholes and Cracks
Filling potholes and cracks promptly is essential to prevent further damage to the driveway. Use a mixture of compacted gravel and a binding agent, such as asphalt emulsion or cement, to fill potholes and cracks. Apply a layer of gravel and compact it using a plate compactor or a hand tamper. For large potholes, apply multiple layers of the mixture, allowing each layer to set before adding the next.
Stabilizing the Gravel Surface
Applying a stabilizing agent, such as a polymer-based or asphalt-based stabilization product, can extend the lifespan of the gravel driveway. Follow the manufacturer’s instructions for application rates and procedures. Typically, a stabilizing agent is applied to the entire driveway surface and then compacted using a plate compactor or a hand tamper. This process can increase the driveway’s load-bearing capacity and prevent rutting and erosion.
