"LQ-II Standard compactor, manual compactor, proctor compactor, light-duty compactor" is used for determining the soil best water content rate, volume and weight. It provides basis to control the soil moisture and specify lowest dencity for road construction.
(1) for in specified tube, do the compact test to the fine soil grains, natural gravel soil, clay sand, gravel material, graded gravel, graded aggregate, etc. for making the water content and dry unit weight curve of soil or aggregate, so that the optimal water content and optimal dry unit weight can be confirmed.
(2) It is better to control the aggregate diameter from 25mm to 40mm (round mesh sieve)
