  • Storage stable emulsions from low penetration grade bituminous binders
    Patent number: 9045624
    Abstract: The present invention relates to emulsions comprising a (1?3)-?-D-glucan, a cationic emulsifier and a bituminous binder having a low penetration. The emulsion is storage stable while fast breaking, even under unfavorable environmental conditions such as high humidity and low temperature. The emulsions can conveniently be used in chip less surface dressings, trackless tack coating compositions, water-proofing compositions, flooring applications, bonding layers, impregnation layers, dense coated materials and semi-dense coated materials which are cold-cast or storable, slurry seals, micro-surfacing compositions and mortars.
