| Abstract: | It shows that using non-nuclear density gauge to measure the compaction degree of asphalt pavement is fast, high efficient, accurate and harmless. In this paper, the working theory, manipulations of non-nuclear density gauge are introduced. Construction quality could be evaluated using non-nuclear density gauge to measure the compaction degree frequently. Kolmogolov principle was used to analyze the measuring results whether they belonged to the same distribution. The conclusion is reached, that using 16m^2/spot measuring method could insure the precision and improve efficiency. |
