Abstract
A process and a machine for forming a bonding layer for bonding a bituminous coated material layer on a support. The process includes application of a surface-active agent on the support, application of a bituminous emulsion on the surface-active agent on the support, and application of a breaking agent on the bituminous emulsion to form the bonding layer. A road-type coating made by the process and, therefore, including such a support layer, a bonding layer on the support, and a bituminous coated materials layer on the bonding layer. To perform the process, a machine includes a frame, a displacement mechanism on the frame, a bituminous-emulsion spreader on the frame, a surface-active agent applicator on the frame, and a breaking agent applicator on the frame.
