What density to use for road material if...
(OP)
Hi there everyone,
I got some test results for some quarry material from a supplier for a road material.
Say for example, if I need to put down the quarried material at 102% Standard compaction effort for a 100m x 10m road at 150mm thick... what's the density I'm actually looking at in the test report? What would the working out be besides volume of the road...
100 x 10 x 0.15 x density??
Right now I'm looking at a report that says the Standard MDD for the material is 1.99, at 9.8% OMC... would that mean I'd be going for the Bulk Density? I.e. 1.99 * (1 + .098) = 2.19 t/m3?
I've always used a "rule of thumb" for base courses and sub base materials through out my career... but would like to be slightly more refined...
Thanks!

The proctor tells you the standard dry density and the moisture content. To get 102% compaction (which is achievable) the standard proctor maximum dry density is multiplied by 102%. Then you add the water content 2.03+2.03x0.098=2.229g/cc or T/m3.
Based on your example above you would have 100m x 10 m x 0.15 m x 2.229 t/m3 = 334 t in place. You should understand that part of the weight is soil and part of it is water, your source material does not come at the optimum moisture content.
