Sustainable Ecological Development Reducing Negative Effects of Road Maintenance Salts

Abstract

abstract. To ensure traffic safety in winter, large amounts of technical salts (chlorides) are applied on roads. De-icing salts directly or indirectly contaminate the road environment and have a negative effect on the components of road environment. The analysis of the situation raises a question: how to ensure traffic safety in wintertime applying salts and achieve sustainable development. The article presents the investigations of chloride concentrations on the roadsides of a highway. In 5 recent years, complex environmental laboratory investigations and investigations under natural conditions of the effect of salts on the components of the road environment have been carried out proving their toxic effect. Consequently, to reduce a negative effect of salts on the road environment, measures of sustainable ecological development have to be taken. To achieve a balanced use of salts, the proposal is to apply alternative materials (formiates, molasses-based material). The introduction of biotechnical measures (an infiltration-grassy ditch, biological and chemical indication on roadsides) is expedient to eliminate the consequences but not the reasons of salt use.Keywords: sustainable ecological development, road maintenance salts, chloride in roadside soil, antipollution of road environment, vegetation saving.reference to this paper should be made as follows: Baltrėnas, P.; Kazlauskienė, A. 2009.

Strategies to Mitigate the Impacts of Chloride Roadway Deicers on the Natural Environment

“…suggested revegetation with salt-tolerant species. Biotechnical methods suggest using a 70:30 mix of perennial rye-grass, because it shows high resistance to the toxic effects of salt, and fescue-grass when building new roads or reconstructing existing road (Baltrenas and Kazlauskiene 2009 This chapter presents information on strategies used to reduce the impacts of chloride deicers once they are in the environment. These are typically defined as structural effective practices; that is, reactive measures implemented along the roadside to physically trap salt-laden stormwater runoff and to allow pollutants to settle out, evaporate, infiltrate, or be absorbed.…”
