Scope

Scope: This document specifies the materials, design, construction, acceptance, and maintenance of permeable concrete pavements with color ceramic particles. This document applies to new construction, expansion, or renovation of pedestrian walkways, squares, and other high-traffic pavements, as well as light-load pavements such as non-motorized lanes and parking lots. Main technical content: This document stipulates the basic technical requirements for the materials, design, construction, quality inspection, and acceptance of permeable concrete pavements with color ceramic particles. 1. The preparation strength of permeable concrete with color ceramic particles shall meet the design requirements and be no less than C20 grade. 2. The mix design of permeable concrete with color ceramic particles shall meet the technical requirements in Table 3. 3. The mix ratio of permeable concrete with color ceramic particles shall be calculated using the filling theory and volume method according to Equation 1, and its strength shall be determined by testing. Equation 1: Mg/ρg + Mc/ρc + P = 1 where: Mg – the amount of color ceramic particles (kg) in 1 m3 of permeable concrete Mc – the amount of binder (kg) in 1 m3 of permeable concrete ρg – the apparent density of color ceramic particles (kg/m3) ρc – the apparent density of binder (kg/m3) P – the designed voidage (%), with a recommended value of 11% to 17% 4. The recommended material usage in each cubic meter of permeable concrete with ceramic particles is: Binder: 55 kg to 90 kg Color ceramic particles: 1550 kg to 1650 kg Binder-to-aggregate ratio: 3.5% to 5.5% 5. The roadbed and subbase of the road should be stable, compact, and have sufficient strength and rigidity, meeting the relevant provisions of CJJ 1. 6. The subbase structure of permeable concrete with color ceramic particles should preferably be a fully permeable structure: 1) The total thickness of the permeable concrete subbase h2 sha
