AASHTO T134 – Standard Method of Test for Moisture-Density Relations of Soil-Cement Mixtures


These methods of test are intended for determining the relation between moisture content and density of soil-cement mixtures when compacted before cement hydration as prescribed. A 944 cm³ (1/30 ft³) mold and a 2.5 kg (5.5 lb) rammer dropped from a height of 305 mm (12 in.) are used and two methods, depending on soil gradation, are covered:
  1. Method A – Soil material passing a 4.75 mm (No. 4) sieve. This method shall be used when 100 percent of the soil sample passes the 4.75 mm (No. 4) sieve
  2. Method B – Soil material passing a 19.0 mm (¾ in.) sieve. This method shall be used when part of the soil sample is retained on the 4.75 mm (No. 4) sieve.
