Expansive soil is a special engineering properties of the soil , its civil engineering has a huge impact and danger . People usually the chemistry improved method improved to achieve the prevention and treatment of expansive soil diseases purpose of strengthening expansive soil . In this paper, the highway expansive soil slope a the DAH conditioner mixed with lime solution penetration improved . First study to explain the impact of rainfall on the slope and hazards , Infiltration calculation model to obtain a test level of one-dimensional soil column infiltration test , based on expansive soil infiltration characteristics parameters of expansive soil in a one-dimensional vertical infiltration problems were calculated and analyzed . Expansive soil characteristics before and after the use of different dosage improver improved through a number of pilot studies , and changes in the strength characteristics and comparative analysis of the effect of treatment of different types of conditioner , summed up the new method in practical engineering applications , evaluation of the actual effect of the treatment and engineering economy . In this paper, the mixed solution of improved expansive soil is an effective way to significantly lower its treatment expansive soil resistance , strength and water stability are greatly improved . This method is particularly applicable to the expansive soil in highway slope protection , and its advantage is that facilitate the construction , the economic benefit is obvious .
