For the prevention of surface-soil erosion, synthetic resin emulsions are used recently as erosion stabilizer. One way of their utilization is to spray synthetic resin emulsion over the surface soil so that the soil particles may be combined together by the elasticity of the resin to form a covering layer united with the lower layer of the soil and thus prevent its erosion.
This method of stabilization is, however, of recent date and there have been but few reports of basic studies that have been made of it, and little is known of the properties of the emulsions themselves as erosion stabilizer.
In the present paper is given an account of the studies we have made of the characteristic features of acrylic emulsions with respect to the properties of erosion stabilizer, and especially the water resistance of the soil which was treated with some acrylic emulsions at various temperature.
The result obtained is that the effect of erosion stabilizer is closely related to the minimum film-forming temperature (MFT) of emulsion, and that particularly when it is treated under the low temperature, the emulsions of low MFT give a good result.
