WINTER MAINTENANCE. THE ACTION OF CHEMICAL SOLVENTS ON HIGHWAY STRUCTURES

LA MANUTENZIONE INVERNALE. L'AZIONE DEI FONDENTI CHIMICI SULLE OPERE D'ARTE

The action of de-icing chemicals on the steel, concrete and reinforced concrete of highway structures is briefly reviewed and it is concluded that the extent of the contribution of these de-icing salts to the damage and deterioration of the structures can be sufficiently determined; it was ascertained that where the de-icing chemicals are not used, the damage is appreciably less. Measures recommended to ensure the maximum resistance of structures to the effects of de-icing chemicals include: A basic design well able to withstand minimum values; slab thicknesses never less than 20 cm; concrete thickness covering reinforcement never less than 2 cm; bonded tendons for prestressed reinforced concrete in preference to sheathed cables; maximum accessibility to bearing and support areas for inspection and maintenance; and protection with high quality resins (epoxy, polyurethane etc). /TRRL/
