Method of manufacturing bulk material covering for tracks, roads, etc

摘要

The method involves pre-sealing the foundation and producing a smooth and/or even surface by vibration, tamping or rolling. The foundation has good drainage properties. The bulk material is coated by a thermoplastic adhesive by application of heat, cooled, and delivered to its place of application as a coated product. The bulk material is sand, pebbles or crushed stone, and can be round or in chip form. The bulk material is produced by adhesion of the individual parts.
