DESIGN AND CONTROL OF SOIL-AGGREGATE ROAD MIXTURES BY MEANS OF THE METAL HYDROMETER

ALTHOUGH THE METAL HYDROMETER METHOD WAS DEVELOPED FOR FASTER FIELD TESTING, LABORATORY TESTING IS STILL NECESSARY FOR DETERMINING THE PLASTICITY INDEX VALUES OF BINDER SOILS. IN PENNSYLVANIA, THE SPECIFICATIONS PERMIT A ZERO PLASTICITY INDEX ON WEARING COURSE, BUT REQUIRE THAT THE BINDER SOIL ORIGINALLY USED MUST HAVE A PLASTICITY INDEX OF NOT LESS THAN FIVE. ALSO THE SPECIFICATIONS PERMIT FROM 10 TO 40 PERCENT OF THE SOIL MORTAR FRACTION OF THE FINISHED MIX TO PASS THE NO. 270 SIEVE DEPENDING ON THE DESIGN BEING USED.
