crushed gravel base course

Crushed Concrete Base Course

The base course, which lies below the surface course of the pavement, may consist of crushed stone, crushed slag is often regarded as the most important structural layer of a pavement. This course ensures efficient distribution of the traffic load and enables adequate sub-surface drainage.

For Class A gravel base course, the field tests taken during any crushing shift shall yield an average of 65% or lower passing the 4.75mm sieve. For Quarried Limestone, a maximum of 7% clean fine sand or any quantity of limestone fines may be added to achieve the required gradation.

Open

Such open-graded (permeable) base courses are intended to serve as subdrainage layers in concrete pavements and as a capillary break that prevents liquid water from rising to the bottom of interior concrete slabs through capillary action in the base course. Open-graded bases are not as stable as densely graded, well-compacted, crushed stone bases.

Crushed Stone vs. Pea Gravel: What's the Difference?

Crushed stone is available in a variety of sizes, from 3/8" to 4". Because it is literally crushed stone, there is no consistency to its shape. The edges tend to be sharper and it feels rougher to the touch than pea gravel. Also, most crushed stone will either be in a white or gray hue, giving you a more neutral look than the colorful pea

Aggregate Base Courses

Aug 14, 2021In order to adequately serve their function, aggregate base course soils must contain enough larger soil particles (gravel, crushed stone) to provide strength and permeability, yet enough fine particles (clay, silt) or additives (chemical stabilizers) to maintain their cohesion and structure under loads. For this reason, aggregate base courses are usually a graded mixture of soil elements
