Scope

Scope: This document specifies the terms and definitions, classification and marking, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of materials for cast-in-place microporous pavement systems. This document applies to materials for cast-in-place microporous pavement systems used in projects with permeability requirements, such as pavements, square floors, and parking lot floors, excluding roadbed cushion layers. Main technical content: This standard specifies seven items including terms and definitions, classification and marking, general requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of microporous ecological cast-in-place pavement systems. It is determined that this standard applies to cement-based microporous ecological cast-in-place pavement systems used in projects with permeability requirements, such as pavements, square floors, and parking lot floors. In the requirements, the technical indicators such as the permeability coefficient, wear resistance, impact resistance, resistance to water erosion, frost resistance, resistance to chemical media, compressive strength grade of the system base layer, flexural strength grade of the system surface layer, bonding strength, bonding strength of the base layer binder, and bonding strength of the pavement protective agent are all clearly specified. In the test methods, the test method standards for each item are determined.
