Samenvatting
The technical committee on winter maintenance presented to the PIARC world conference at Mexico a report on the influence of chemical substances used to fight winter weather conditions on the environment. This study demonstrates that the situation is not alarming, but that measures can be taken to avoid accidental damage and to limit the quantities of salt used. An article summarizing the report is published in the issue of "revue generale des routes et des aerodromes", no 519, april, 1976, pp 84-86. For the covering abstract, see IRRD abstract no 104484.
