Effect of vibrating compaction method on the optimum water content and dry density for the cement-stabilized crushed rock mixtures;

Influential factors of maximum dry unit weight and optimum water content of lime-flyash concrete;

This paper starting from the characters of the "rubber soil",basing on overall-analyzing the mechanism of production of rubber soil and by means of corresponding compaction tests,emphasis on researching the optimum water content and the maximum dry density of the clay in the progress of compaction,and discussing prophylactic-therapeutic measures of it.

Optimum moisture content of rapeseed for ultradry storage at different temperature;

Using the regress analysis method and the numerical analysis method to obtain the extremum of the compaction test,we may accurately extract the biggest dry density and the optimum moisture content.

The density is one of main control performances for projects during the highway construction, optimum moisture content and maximum dry density among them are keys for calculating and controlling the density.

So the relationship curve of effective thickness of water film versus inherent properties of aggregate can be utilized for estimating optimal water content during material composition design of unbound graded aggregate base,with sum of specific surface area of aggregate grade calculated.

Based on the conditions of construction,it is suggested that the proportion of lime is 6 to 7 percent,the optimal water content is 15 to 18 percent,the maximum dry density is about 18.

It introduces the interface of Origin,discusses the application of Origin in geo-technical hit-solid experiment,and points out that it can fit the high quality hit-solid curve,and using the data express tool of it,it can be defined speedily and correctly of the maximum dry density and the best moisture content,to prompt the application of Origin in geo-technical hit-solid experiment.

Through the calculation of numerical software of MATLAB and so on,it s easy, it gives theory reference to solve the maximum dry density and the best moisture content of rock,to prospect the get prompting and application in managing of geotechnical experimental data.
