(DOC) Laboratory Comparison of Crushed Aggregate and

To properly design a pavement with RPM as base course materials, it is imperative to test or estimate the above mentioned engineering properties. Unlike traditional base course materials, such as crushed aggregate, the engineering properties of RPM are not readily available. Kim et al studied the resilient modulus of RPM (5).Get price

Crushed Limestone Concrete Aggregate

Second, because crushed limestone has a lighter unit weight than gravel, it will require about 12% less crushed limestone than gravel to mix a cubic yard of concrete. Additionally, crushed limestone concrete is easier to saw through than gravel concrete. This is because most gravel is silica. Silica is almost impossible to cut with a steel saw.Get price
