Which important tests required on crushed stone base?
(OP)
I'm current supervising a road designed to a bitumen stard-surface dressing.The pavement layers composes of stabilised base,crushed stone base(CRR)and surfacing.Now I'm at base course stage and in principal I have already analysing the most important tests required for the assessment of the rock to be used as stone base.The test already conducted are grading analysis,P.I,ACV,LAAV,SSS(5cycles)and TFVdry/TFVsoaked.Is pertographic analysis important in this case?and what else important tests to be conducted?





RE: Which important tests required on crushed stone base?
Unless you suspect some type of aggregate reactivity, I would not recommend petrography for this. Have you done abrasion testing? Even though it is a base material, and not subject to direct traffic abrasion, the test gives you a good idea of the aggregate's general durability.
My guess is that you are in UK,S. Africa, or Australia...your acronyms are unfamiliar to me. I'm in the US
