A rule of thumb used in the construction of South African G1 base course layers is that OMC values less than 4% are indicative of too few fines in the aggregate matrix, whereas OMC values higher than 6% are indicative of …

Base courses are usually constructed out of crushed aggregate or HMA. Subbase Course. The layer between the base course and subgrade. It functions primarily as structural support but it can also minimize the intrusion of fines from the subgrade into the pavement structure and improve drainage. The subbase generally consists of lower quality ...
