MASTIC SURFACINGS STABILIZED WITH CHIPPINGS AND PLACED ON OKTA ADHESIVES AS SURFACINGS FOR ORTHOTROPIC BRIDGE SLABS

Practical experience has shown that the durability of surfacings on orthotropic decks can only be guaranteed if the surfacings are firmly bonded to the metallic base. They must also withstand thermal and traffic stresses and have sufficient stability at high temperatures. A satisfactory method of construction consists in placing an adhesive on the bridge deck and covering it with a mastic layer and a further protective layer. A new method which has been developed combines the advantages of a mastic layer and the protective action of gussasphalt in one layer. The mastic layer contains chippings which are twice crushed and screened and rolled in with a static roller and also has an admixture of highpolymers to improve the adhesion strength. Gussasphalt, fine asphaltic concrete or aspiphalt can be used as a top course. An important role is played by the Okta adhesive which also gives protection against corrosion. /TRRL/
