The Importance of Gravel in Road Construction

February 14, 2024

Take a moment to visualize the intricacies of society—multi-story buildings, the interplay of roads, the constant influx of energy. Amidst this complex network, our daily commutes remain grounded—literally—by a surprisingly simple element: gravel. At first glance, it may seem unassuming, but its importance in road construction is monumental. United Companies is deeply aware of the vital role this humble, yet essential material plays in facilitating progress and enabling a society in motion.

The Fundamental Role of Gravel

Gravel’s function encompasses more than just forming a sturdy surface; it is also integral to the durability and uniformity of the road structure. As the structural foundation, gravel’s blend of tiny rocks, silt, clay, and sand possesses high compressive strength and excellent load-bearing attributes, qualifying it as the cornerstone of global road systems. Beyond that, over 2 million miles of roads in the United States are unpaved, and largely composed of gravel.

Gravel for Effective Drainage

Probing further into gravel’s use, its permeable nature provides a proficient drainage system, crucial during high precipitation conditions. Facilitating rapid water flow, gravel defends against water accumulation, resisting premature road degradation. Waterlogged roads are not merely inconvenient but hazardous, reinforcing gravel’s contribution to road safety.

Gravel in Erosion Control

The role of gravel in preventing soil erosion cannot be overstated. Particularly in hilly terrains where roads are built, the deliberate placement of gravel decreases risks of landslides by providing resistance to downward forces, emphasizing once more the safety parameters of its application. In a practical sense, gravels’ employment in road construction has witnessed up to 34% reduction in soil erosion.

Environment-Friendly Road Construction with Gravel

It’s crucial to acknowledge that beyond its technical role, gravel also plays an important part in eco-friendly road construction. This environmentally responsible choice, has low environmental impact due to the more sustainable extraction and usage processes utilized. Herein lies its value as a viable alternative, in a time where focus has been significantly pivoted towards sustainable practices.

The Latest Advancements

One can’t help but marvel at the advancements gravel technology has seen in the world of road construction. We’re talking about innovations that have developed gravel into something more robust and cost-efficient – courtesy of geogrid technology. Or how about resin-bound gravel, which envelops us with its smooth, weather-resilient surface and an underlying tone of eco-friendliness. Cold recycling certainly deserves acknowledgement, breathing new life into old asphalt while conserving energy and resources. Then there’s self-binding gravel, its clay component making roads resistant to natural erosion. These breakthroughs have redefined gravel as not just a bunch of stones but as a technological instrument geared towards building sustainable, economical roads.

Paving Our Progress with Gravel

A simple truth surfaces when we reflect on elements that have profound impacts on how we shape our society. Gravel in road construction unveils this truth. It is a perfect example of how we blend science, art, and wisdom in our road construction processes.

When we think about gravel, there is a clear realization of how much we can do with simplest of materials. Our drive to combine necessity and environmental preservation mirrors our journey to progress. It is this progress that paints a picture, shaping our world with every road constructed and mile traveled.
