Abstract
"Sugar scum" or "carbonation mud," which is a residual product of the purification of sugar juices, e.g. beet, is mixed with bitumen which melts between 40 and 65 DEG C. such as petroleum bitumen. The scum contains precipitated calcium carbonate and flocculated colloidal lime salts such as lime pectate. The mixing may be performed by adding the scum in the form of an aqueous paste or a dry powder to an aqueous emulsion of bitumen, the mixture being then dried and pulverized; or by grinding the bitumen after cooling or pulverizing, after heating, with a jet of air, and then adding it to the aqueous paste. The grains or drops of bitumen are said to be coated with particles of the scum, so that the mixture can be kept in a granulated form. Mixtures containing upwards of 20 per cent of bitumen can be obtained. To p the mixture may be added, for making a road composition, cold or hot tar or heavy oils derived from coal or petroleum and aggregates such as sand, gravel and slag. The Specification as open to inspection under Sect. 91 contained references to the use of finely-divided substances other than sugar scum for mixing with bitumen, whereby, it was stated, the bitumen particles were coated. This subject-matter does not appear in the Specification as accepted.
