— For maximum base stability, the granular base should have sufficient fines to just fill the voids and the entire gradation should be close to its maximum density. However, while base density is maximized at fines content between 6 and 20 percent, load-carrying capacity decreases when the fines content exceeds about 9 percent.

Granular soil offers ultimate load carrying capacity and can be compacted easily. Cohesive soil does not provide bearing strength as much as granular soil. additionally, it may suffer from shrinkage and settlement and hardly compacted when it is wet. Finally, cohesive soil requires great effort to make it suitable for subgrade of concrete floor. 2.

This Tarmac Granular Sub Base MOT 1 is ideal as a sub-base for driveways and paths when compacted, with excellent load bearing properties. MOT Type 1 is a crushed aggregate material used to provide a stable sub-base for road surfaces and pathways. Read more. Read less. View product details.
The sub-base is finely graded, with a maximum size of 63mm. Once compressed, the gravel blends to form a robust flat surface with few gaps, creating a smoother road that minimises potholes and preserves your pavement.
B. Granular Subbases. Purpose: Subbases serve a variety of purposes, including reducing the stress applied to the subgrade and providing drainage for the pavement structure.
— SUB- BASE GRANULAR Es la capa formada por la combinación de piedra o grava, con arena y suelo, en su estado natural, clasificados o con trituración parcial para constituir una sub-base integrante de un pavimento, la cual está destinada fundamentalmente a soportar, transmitir y distribuir con uniformidad el efecto de las …
The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and …
