1 1/4 MINUS CRUSHED SURFACE BASE COURSE
Roads, much like homes, are only as strong as the foundation they are built on. The go-to base material for heavily trafficked roadways is crushed surfacing base course (CSBC), which gives roads the foundation they need. This article goes over why the material is so effective and how you can go about obtaining and having it installed.
HOW CRUSHED SURFACE BASE COURSE WORKS
Though only the top layer is visible, roads are actually made up of multiple layers. As the name implies, the base course of a roadway is located under the top layer of a roadway and provides support to the material above it, which is usually asphalt. Aside from supporting the upper layer of the roadway, the base course also contributes to drainage, according to industry website PavementInteractive.org. (There may be an additional layer under the base course, called a subbase course, but this is not the case in all instances.)
CSBC is effective as the second layer of a roadway because its traits allow it to do both jobs required of a base course. CSBC is made up of small, crushed stones. Because they are so small, they can be packed very tightly together, which adds to the material’s stability. They are still somewhat permeable, however, which allows for the drainage required of the second layer. Additionally, CSBC can boost the stability of bridges, and it is also useful in areas that are prone to being wet or muddy.
The CSBC used by Reece Aggregates and Recycling meets the Washington State Department of Transportation’s base-course specifications.
