Whether curing is priced separately when applying quotas to cement-concrete pavement: Beijing DB11/T 2382-2024, Shenzhen SJG 181.1-2024, and the highway quota all include curing

Topic Positioning

For cement-concrete pavement in municipal/highway budgets and BOQ compilation: which quota sub-item applies, whether curing is comprehended in the quota work content, and whether it must be listed separately. Covers three calibers: Beijing's municipal consumption standard, Shenzhen's, and the highway budget quota.

Core Conclusions

1. Beijing caliber (DB11/T 2382-2024, municipal works)

• Cement-concrete pavement surface applies the "cement concrete surface course" sub-item: D2-2-20 cement concrete surface course, 18 cm thick, unit 100 m2;
• Its work content verbatim: "placing, vibrating, troweling, texturing, curing, etc." — curing is in the quota work content, not to be listed separately in budgets/BOQs; the standard's municipal part sets no independent "concrete pavement curing" sub-item;
• Sub-item consumptions (per 100 m2): composite labor class II 8.2760 workdays; ready-mixed concrete C30 18.18 m3; nylon disc D100 1.5%; other tools 2%.
• Companion rules: surface-course quantities by design dimensions in area, not deducting manholes, but deducting flush channels where present; bridge-deck asphalt overlay does not deduct expansion joints (Clause 7.2.3). Formwork quantities are computed by contact area between concrete and formwork (Clause 7.2.21); formwork, grooving, etc., follow their own sub-items.

2. Shenzhen caliber (SJG 181.1-2024 municipal consumption standard, Vol. 1: roads)

• Verbatim: "Cement-concrete pavement placing comprehensively considers pavement curing, not computed separately."

3. Highway caliber (JTG/T 3832-2018 system; Beijing ordinary highway major/minor repair budget quota)

• Sub-item 2-3-8 cement concrete pavement, work content verbatim includes: "... manual placing of concrete, placing, compacting, vacuum dewatering, leveling, texturing, curing; 4) grooving, filling sealant." Curing is likewise included;
• The sub-item is listed by ordinary/fiber concrete, paver vs manual placement (rail, slipform), thickness 20 cm and each +/-1 cm.

4. General verdict When compiling, first read the work-content column of the applied sub-item: if it contains "curing", curing is not counted again — Beijing, Shenzhen, and the highway caliber agree that routine curing of cement-concrete pavement is comprehended in the placing sub-item.

Applicable Boundaries

• "Included" means the routine curing methods considered by the quota (water spraying, covering for moisture retention); where the design or codes require special curing processes, handle per the applied quota's notes and the contract;
• Municipal and highway are two quota systems with different sub-item numbers and units: the verdict is the same but application follows the project's system; other provinces must check their local standards — the sub-item numbers here map only to their own standards;
• The conclusion targets the cement-concrete surface placing sub-item itself; grooving, sealant, texturing, formwork, etc., follow each standard's sub-items or rules;
• Quantity rules follow the project location's standard (e.g., Beijing: no manhole deduction, flush-channel deduction).
