Can a newly constructed cement road accommodate cars after 2 days?

Newly constructed cement roads can accommodate cars depending on specific curing conditions: 1. Normally, cast-in-place concrete with natural curing can allow car traffic within 2 days, but if the concrete strength has not reached C12, it should not be opened to traffic; 2. Generally, rural cement roads require a minimum curing time of no less than 4 days. For the five commonly used types of cement, the curing time under normal temperature conditions should be no less than 7 days. If additives are included or there are anti-freezing requirements, the curing time should be no less than 14 days. Cement roads refer to pavements with cement concrete as the primary surface material, also known as rigid pavements, which are a type of high-grade pavement. Cement pavements include plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete, and various other types of pavements.
I usually drive very carefully. You absolutely must not drive a car on newly paved cement roads within the first two days. The cement doesn’t cure that fast—it usually takes about seven days to gain some strength. In the first few days, there’s a lot of moisture, and the surface is soft. If a car drives over it, it will definitely leave dents or cracks. I’m not exaggerating—last year when they paved the road in my hometown, my neighbor drove on it on the third day, and the wheels sank in, nearly causing the car to flip. What’s worse, it’s bad for your car too—the chassis could get scraped, and the tires will wear out faster. Safety first—wait a few more days, check that the road is dry and hard before driving, and don’t take the risk.
