| 摘要 |
A consumable bitumen packaging compound including at least one packaging material/s, such as polymers, plastics and extenders and the like, used in combination with the bituminous material and a metal, either pure in powder form or in the form of salt or oxide, that is physically and/or chemically combined with the polymer material, so that the density of the packaging material is adjusted to prevent the material from floating to the surface of the molten material after melting. The components of the packaging are preferably selected such that they are compatible with the bitumen. After transport and storage, the packaging material can therefore be directly incorporated into the bitumen product for final use, such that the formation of a polymer skin accumulating at the surface of the molten material is largely avoided. |
