Aggregate Base Preparation: what to know
The granular base spreads loads and provides a consistent platform for asphalt surfacing.
For aggregate base preparation, the first step is to understand the site rather than assume that a visible surface problem has only a surface-level cause. Existing materials, traffic use, access, slopes and water movement shape the options worth considering.
Key considerations
- Remove soft or unstable soil when needed
- Place suitable aggregate in compactable lifts
- Check grade and density before paving
Planning the next step
Before discussing aggregate base preparation, record the intended use of the space, approximate dimensions, existing surface conditions, and whether water collects or moves across the work area. Photographs, measurements and a list of practical constraints can make an early conversation more productive.
The final design and construction method should be established after a site assessment by a qualified local contractor. Confirm the proposed materials, project boundaries, drainage approach and any access limitations before scheduling work.
