According to the Chaptet 02742 of Specification the thickness and compaction of the pavement are very important for the quality of construction but in reality only saturated surface dry method (SSRD) other than wax sealing Method (WSM) was usually adopted in experiments. This research is proposed to adopt three experimental mthods including direct measurement method (DMM), SSRD and WSM, and two kinds of specimens:, the Marshall specimens and drilled specimens. Different contents and mixtures are tried and tested for investigating the difference. Experimental results show that DMM can onlybe used for measurement of Marshall specimen, submerge time has no obvious effect in SSRD, the maximal difference of measured thickness and unit weight between WSM and SSRD may reach 0.06cm and 0.85%, respectively. Finally overall grey correlation was employed and the results depict that volumetric specific weight and unit weight play the most important role among the content of specimen.
