- Technical Specification (Requirement Specifications)
Prevent plastic from ending up as uncontrolled waste (pollution) and dispersed in the natural environment, either during the construction phase or through subsequent replacement.
It is difficult and inappropriate to impose a general requirement that the use of plastics must be avoided. The risks that the various products will entail will vary. As regards explosives, ignition systems with plastic hoses may be used, which can cause plastic residues to be lost in aggregates and end up in the natural environment. Plastics used in underground pipes do not necessarily represent a challenge as regards the generation of uncontrolled waste (pollution) and dispersal in the natural environment. However, it will then be important to maintain control over microplastics and waste when cutting pipes. Plastics used as a sealing membrane can also have good environmental properties compared with chemicals which are applied to joints.
Measures must be implemented to reduce the use of plastics in the project. Macro-polymer fibres must not be used in spraycrete for rock stabilisation purposes.
Documentation of the Requirement Specification:
Documentation of measures and the assessments that have been carried out, minutes of meetings, memos, etc.
Information about the Requirement Specification:
Plastic reinforcement in spraycrete is a source of pollution. The Norwegian Public Roads Administration has carried out an assessment of the consequences of banning polymer fibre in spraycrete and concluded that it would be prudent to impose appropriate technical requirements in cases involving aggressive environments.
