Claims
- 1. A process for coating a structure with a composition which comprises (a) 80 to 99%w of a bitumen component; (b) 1 to 20%w of an elastomer; (c) 1 to 60%w of a hydrocarbon resin which has been modified to contain carboxyl, carboxylic anhydride, hydroxyl and/or amino groups; and (d) 1 to 100%w of an inorganic filler, the weight percentages being based on the total weight of the bitumen component and the elastomer; wherein the structure is first coated with a primer which comprises bitumen and at least one resin in a solvent; and then, at elevated temperatures, the composition is applied onto the primer coating.
- 2. The process as claimed in claim 1, in which the primer also contains a block copolymer, a hydrogenated block copolymer of a monovinylaromatic hydrocarbon and a 1-alkene and a conjugated diene.
- 3. The process as claimed in claim 1, in which the composition is applied onto the primer coating at a temperature of from 120.degree. to 210.degree. C.
- 4. An article coated with an asphaltic composition according to the process of claim 1.
