Scope: 1.1 This document specifies the terms and definitions, classification, marking, general requirements, requirements, test methods, sampling methods, and inspection rules for green ecological aggregate concrete kerbstones (hereinafter referred to as ecological kerbstones). It also covers general provisions, requirements, test methods, sampling methods, and inspection rules, as well as marking, product quality certificates, user manuals, and packaging, transportation, and storage. 1.2 This document applies to concrete kerbstones made from green ecological aggregates and cement as the main raw materials, which are prefabricated by vibration or other methods and used for laying on road edges, road boundaries, and water drainage. Their visible surfaces may have a surface layer (material) or no surface layer (material), and may be natural-colored, colored, or surface-processed. Main Technical Content: 5.3 Shape 5.3.1.1 Ecological kerbstones should have complete edges and corners, intact shapes, and smooth surfaces without through cracks. The visible surfaces of the kerbstones should have chamfered or rounded corners, except for angles formed by slopes, arcs, or chamfered corners. All other angles should be right angles. 5.3.1.2 The thickness of the surface layer (material) of ecological kerbstones, including any part of the surface with chamfered or rounded corners, should not be less than 4 mm. 6 Requirements 6.1 Green Ecological Aggregate Utilization Index and Green Ecological Grade 6.1.1 The green ecological aggregates utilization index of ecological kerbstones should not be less than 30. 6.1.2 The requirements for the green ecological grade of ecological kerbstones should comply with Table 6.1. Table 6.1 Green Ecological Grade of Ecological Kerbstones Level I Level II Level III Green Ecological Aggregates Utilization Index ≥70 ≥50 ≥30 Visual Quality The visual quality of ecological kerbstones should comply with Table 6.2
