Base & Subbase
Base and subbase
Continuously graded mixes for load-bearing pavement and foundation layers.
About Base and subbase
Base and subbase layers spread traffic loads through the pavement foundation. Continuous grading, fractured faces and plasticity of the fines determine their compactability and bearing capacity.
In Iran these materials are specified mainly under Publications 101 and 234 and each project's particular specification.
