It was developed during the late 1950’s from single stage crusher-run material that complies with Fuller curve particle grading and very strict material and construction specifications.

GSB or granular sub-base prevents capillary water from rising; its particle size is so designed that the capillary action stops and cant go beyond GSB layer. Secondly, it works like a drainage layer where water can pass without damaging other road layers.
