Crushed stone is the most common material for use in the aggregate of bedding course. The aggregate for the bedding course of permeable roads needs to not only meet the requirements of basic mechanical properties but also ensure permeability and structural stability. This work analyzed permeability under extreme rainfall conditions and the particle mass loss during permeation and then ...

Subbase is the secondary loadspreading layer of the pavement. It is usually either crushed stone, broken brick aggregate (frequently mixed with sand) or locally available gravel. Improved Subgrade is imported material ( fine or coarse sand) that is locally available. It is intended to act as a cushioning layer between weak subgrades and the road pavement layers. If the subgrade is of ...
