Question: What is the recommended thickness of aggregate base needed to construct a standard concrete driveway?
Top Answer (39% of 58 votes): 4-6 inches.

Answer: 4-6 inches
Explanation: The recommended thickness of aggregate base for constructing a standard concrete driveway typically ranges from 4 to 6 inches. This aggregate base layer serves several important purposes: 1. Support and Stability: The aggregate base provides a stable foundation for the concrete slab above, distributing the load of vehicles and preventing settling or unevenness. 2. Drainage: Properly compacted aggregate facilitates drainage, preventing water from pooling under the concrete slab, which can lead to erosion and cracking over time. 3. Subgrade Protection: The aggregate base layer protects the subgrade (the native soil beneath) from damage caused by freezing and thawing cycles, moisture fluctuations, and compression from vehicle loads. Key considerations: Compaction: Proper compaction of the aggregate base is crucial to ensure uniform support and stability. Compaction should be done in layers to achieve the desired density and strength. Quality of Aggregate: Use quality aggregate material that meets local specifications and is free of organic matter, debris, and excessive fines. Thickness Variation: The thickness of the aggregate base may vary depending on soil conditions, climate, and anticipated traffic loads. In some cases, particularly heavy-duty applications or poor soil conditions, a thicker aggregate base may be recommended. By following these guidelines and ensuring a well-prepared aggregate base, you can help ensure the long-term durability and performance of your concrete driveway.
