What are the differences between capping layer and sub-base?

In order to save cost for sub-base which is relatively expensive, the concept of capping layer is introduced in which capping materials of cheap but strong nature are used to cap the weak subgrade. In this way, the thickness of expensive subgrade is not required to be increased. Crushed gravels and rockfill may be suitable options of cappingget price

Paving Expert AJ McCormack and Son FAQ for Sub-bases

DTp1 has, in theory, a maximum particle size of 37½mm, so using this 'rule of thumb', the min layer thickness would be 3½ × 2 = 75mm. If a fill layer or sub-base layer was using a 50mm crusher run material, then the minimum layer thickness/depth would be 50 × 2 = 100mm, and so on and so forth.get price
