BS ISO 15643:2020 Road construction and maintenance equipment — Bituminous binder sprayers and synchronous bituminous binder sprayers-chip spreaders — Terminology and commercial specifications. 1 Scope This document establishes the terminology and the content of commercial literature specifications for bituminous binder sprayers and synchronous bituminous binder sprayers-chip spreaders (i.e. synchronised combined units) including their components and their technical characteristics. This document covers cold and hot bituminous binder sprayers. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 15644, Road construction and maintenance equipment — Chippings spreaders — Terminology and commercial specifications 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 15644 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https://www.iso.org/obp — IEC Electropedia: available at http://www.electropedia.org/ 3.1 bituminous binder sprayer machine used to apply a film of bituminous binder on a pavement at a predetermined application rate Note 1 to entry: The particular sprayer types may be defined by associating the operating principle, the shape of the components, the type of binder, and by specifying the spraying performances. 3.2 synchronised combined unit synchronous bituminous binder sprayer-chip spreader machine which consists of a combination of bituminous binder sprayer (3.1) and chip spreader, used to make synchronised application of bituminous binder and chips on a pavement at predetermined application rate for a complete road surface treatment 3.3 displacement pump sprayer bituminous binder sprayer (3.1) in which bituminous binder transfer from the storage tank to the spray bar is provided by a pump Note 1 to entry: The pump’s output is proportional to its rotating speed which may be controlled by the vehicle movement speed. 4 Description of sprayer components 4.1 Transport vehicle The vehicle, in the form of a truck, trailer or semi-trailer, carries all the components and provides movement of the sprayer during spraying and during road transfers. 4.2 Tank The tank is used to store the binder during work and transport. It may have a facility to heat the binder and may have a system to prevent loss of heat, e.g. a heat- insulated...
