2021-8-21  Granular Sub Base is a layer in road foundation just above the compacted sub-grade layer. 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.

2005-8-6  However, my question is can you accurately test compaction of #610 stone? I thought the only stone that you could test accurately was dense grade aggregate or DGA. Although #610's has some fines in it and is more dense than #57's I am inclined to think that there are still to many voids and compaction tests would not be accurate.
