base course

The layer(s) of a specified material of designed thickness placed on a sub-base or subgrade to support the surface course. The base course and subgrade are structural elements of the pavement. In conjunction with the overlying asphalt surface, their purpose is to distribute traffic wheel loads over the whole foundation. Also called a base.

Puzzolanic cement can be an effective solution to improve base course performance by means of bearing capacity and permeability.
Analysis of the results of pavement structure bearing capacity shows that the highest values are obtained in pavement structures where the thicker (30 cm) base course of crushed dolomite was used, also where the base course was constructed with reclaimed asphalt 10 cm plus crushed dolomite 10 cm.
Clearly, the advantages are many, and whether material is used as base course or back as aggregate, on-site practices are now well established.
