Understanding Dust Control Methods for Gravel Driveways

Managing dust on gravel driveways is essential for keeping the surface clean and stable. Chemical dust suppressants like calcium chloride and magnesium chloride are effective options. These hygroscopic agents attract moisture from the air, keeping the gravel damp and significantly reducing dust for weeks after application. They can be applied using sprayer trucks or handheld spreaders for an even finish. Dust forms when loose soil or dirt particles escape from the ground surface, contributing to the need for effective control measures. For a quick fix, regular watering can help control dust but requires frequent effort. Additionally, soil adhesives and stabilisers, such as Ground Glue®, help bind gravel particles together, improving stability and minimising dust. Combining these methods often provides the best results for maintaining your gravel driveway.

Choosing the Right Gravel Mix

When selecting the right gravel mix for your driveway, focus on aggregate size and quality. Choose coarser materials that interlock well, as these reduce dust and improve stability. It’s also wise to consider dust control features, like a balanced mix of fines and robust rock types, to ensure your driveway lasts. Additionally, incorporating dust control products like calcium chloride or magnesium chloride can significantly enhance the longevity and effectiveness of your dust suppression efforts.

Aggregate Size Importance

Choosing the right gravel mix for your driveway is crucial for stability and longevity. Aim for gravel sizes between 20mm and 25mm, as this range allows for optimal compaction and load distribution. Smaller sizes, under 6mm, can become unstable under the weight of vehicles, while larger gravel lacks the necessary interlock, leading to a loose surface. A well-graded mix, combining both larger stones and finer particles, improves compaction by filling gaps and reducing dust. Additionally, using #57s gravel is recommended for its effectiveness in creating a compact and durable surface. This mix also supports effective drainage, preventing water pooling and erosion. By selecting the correct aggregate size, you ensure a durable, dust-free driveway that can withstand both time and traffic.

Quality Gravel Selection

Selecting the right gravel mix is crucial for the performance and longevity of your driveway. Keep in mind the following gravel selection criteria, including composition and colour, to help minimise dust.
