Can cars drive on cement after 48 hours?

[JamesRose]

For newly constructed cement roads, whether sedans can drive depends on specific curing conditions. Normally, cast-in-place concrete with natural curing allows sedan traffic within 2 days. However, if tests show the concrete strength hasn't reached C12, the road shouldn't be opened to traffic. Relevant details are as follows: 1. Duration: Rural cement roads generally require minimum 4-day curing period. For common five cement types under normal temperatures, curing should last no less than 7 days. With additives or frost resistance requirements, the period shouldn't be shorter than 14 days. 2. Curing: Watering frequency for cement road curing closely relates to climate conditions. In hot weather, curing should last no less than 14 days, while in cold weather no less than 21 days. Otherwise, heavy vehicles may damage the surface and affect concrete durability. In hot weather, early curing should continue until upper concrete layer pouring. To prevent watering damage, covering concrete pavement with non-woven fabric felt is recommended.
