A test has been developed for the rapid measurement of a 'moisture condition value' (mcv) of earthwork material. It is intended as a means of assessing the suitability of earthwork materials for use in embankments while avoiding the measurement of moisture content with its associated delays. Evidence is put forward to indicate that a new method of soil classification could be based on the characteristics of the moisture condition calibration line (the straight line relation between moisture content and mcv). Relations between the undrained shear strength of remoulded soil and mcv have been established, and there are also strong possibilities that CBR can be predicted from mcv. It has been found that the performance of earthmoving plant can be related to mcv and the effects of variations in mcv on the depth of rut, speed of travel, and losses in productivity caused by 'bogging down' during the operation of medium scrapers (15 to 20 M3 struck capacity) are given. The possible applications of the moisture condition test in the prediction of the relative effects of wet weather on different soils and the degree of difficulty of compacting different soils are also discussed.
