A good road base should cover the surface soil completely and be able support heavy vehicles evenly. And depending on the weight and amount of traffic and weather, the base can be as deep as thirty inches. Our rock base is made up of crushed concrete and stone screenings. No matter if you need rock base for a driveway or highway, we have the amount and quality you are looking for.

Thus it is desirable that the road stones used in the construction should be sound enough to withstand the weathering action. The property of aggregates to withstand the adverse actions of weather may be called soundness. 5. Shape of Aggregate. Road aggregates may be rounded, angular, flaky or elongated. Flaky and elongated particles have less

Here are 7 key points to keep in mind to make the best gravel road. 1. Understand Your Needs. Before construction begins, it is necessary to understand the needs and uses of the area where the road is going. Heavy industrial vehicles used for farming, for example, can wreak havoc on a gravel roadway if it is not strong enough, as the DOT exmplains.

They are often confused for one another since both gravel and crushed stone come from rocks and are aggregates used for construction projects. But these two aggregates serve different uses. Ultimately, if you want an aggregate for construction, such as building, paving, and any hardscaping, go with crushed stone.

Much of the crushed stone is also recycled right on the construction site, especially with road construction, and this makes it difficult to measure. The most common use for recycled crushed stone is as a base for roadways, especially when the old road can be torn up, crushed, and reused.

Stones for construction purposes are obtained by quarrying from solid massive rocks. The stones used for masonry construction should be hard, durable, tough, and should be free from weathered soft patches of material, cracks, and other defects that are responsible for the reduction of strength and durability.
