Abstract

Laboratory experiments indicate that spray-applied biopolymer mixtures and biopolymer admixtures for compacted soil may offer cost effective means of mitigating wind-induced soil erosion. Mitigating wind-induced erosion can be a serious geotechnical consideration due to the associated soil loss and air and water quality impacts. Agricultural soil loss is a serious concern worldwide. Air quality problems due to wind-induced erosion of fine grained soil (fugitive dust) from construction sites are common in arid and semi-arid regions. Conventional techniques for wind erosion control include frequent watering of the soil, application of covering materials (e.g. geosynthetic rolled erosion control products), and application of chemical stabilizers (e.g. hydrocarbon emulsions or synthetic polymeric emulsions). All of these techniques have limitations: application of water may require continuous treatment, particularly in relatively hot and arid climates; covering with geosynthetic materials can be expensive; chemical stabilizers can be expensive and have adverse environmental impacts. Biopolymers may offer a cost-effective alternative to these conventional techniques. Laboratory testing shows that surface application of a biopolymer emulsion can significantly increase the resistance of sandy and silty soil to wind-induced detachment. Experiments also suggest that the crust formed by the application of the biopolymer emulsion may be relatively stable in the field for an extended period of time. Compaction of soil with a biopolymer admixture, though more expensive than surface application, can achieve similar results and may provide enhanced resistance to surface water-induced erosion. Furthermore, the impacts of introducing the biopolymer into the environment are expected to be relatively benign.
