• Type 1 subbase density – Materials Man

    So in my humble option you should use / t/M3 for aggregate that has a relative density of / t /M3. Limestone will be less in proportion to it's relative density as will granite, and some igneous rocks will be more, such as from Hillhouse Quarries in Ayrshire whose relative density from memory is t/M3. the lack of facts is ...

  • What is Type 2 aggregate base?

    Apr 03, 2020· The (150180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150180 lb/ft^3).
