The entire subbase and base system should be at least 4 inches thick—thicker if the engineer feels it is needed for proper support. The base course material, according to ACI 302, "Concrete Floor and Slab Construction," should be "compactible, easy to trim, granular fill that will remain stable and support construction traffic."
Base Materials The base layer is the second layer of road pavement which has a specific characteristics and thickness on the sub base layer and it is constructed on the entire width. The function of the base layer in the pavement is as follows: Loads Bearing

The subbase layer works by distributing the surface load over a wide area, and it dramatically improves the ability of the top surface to carry heavy loads and maintain integrity notwithstanding long and repeated use.. The value of a properly laid subbase layer, even a thin one, cannot be overestimated. Just a few centimetres of crushed aggregate can help ensure a reliable .
Product Details: Crushed Stone Aggregate is a broad egory of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Crushed stone or Stone or angular rock is a construction aggregate.

Base course. The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field. It is loed under the surface layer consisting of the wearing course and sometimes an extra binder course . If there is a subbase course, the base course is constructed directly above this layer.
Gabbro rock is an intrusive igneous, dark, and coarsegrained rock. This rock is usually black or dark green and is mainly composed of plagioclase and augite minerals. Gabbro rock is the most abundant rock in the oceanic crust. It forms when volcanic lavas fall under the surface of the earth and got cold in the shape of crystalline masses.
