BLUESTONE

BLUESTONE

(OP)
Is using bluestone mixed with soil able to support a roadway?

RE: BLUESTONE

technician06...your question doesn't offer enough background for adequate input.

First, "bluestone" is a colloquial term to describe certain greywhacke or sandstones.  I assume you are somewhere in PA/WV/NY or somewhere along the middle ot upper Appalachians.  

The material itself, if crusher run and well graded can serve as a base material or as a stabilization material when mixed with sand.  Are you considering using spoil materials from a stone quarry operation where architectural stone is produced?

Can it support a roadway?  That depends on the type of roadway and whether there are other components of the pavement section to consider.  To mix bluestone alone with sand would not produce a very good "roadway", but would provide a good starting point for the building of a pavement section.  Above that you would typically install a base material and above that, an asphaltic concrete layer or layers, depending on the traffic type, frequency, and other design conditions.
