The Complete 7

This process involves undercutting the sub base, but instead of removing all of the soft clay and soil, it is instead mixed with added aggregate to improve the strength of the compromised areas. Step 5: Binder and Surface Course . Once the sub base is laid and any soft areas are identified and repaired, it is time to add the binder.
