Answer: B. Rapid hardening cement

For road pavements, the cement generally used is rapid hardening cement.

Solution

Rapid Hardening Cement (RHC) is a type of cement that has a higher rate of gain of strength as compared to OPC. RHC attains the same strength in 3 days that OPC may attain in 7 days. The ultimate strength of rapid hardening cement is the same as that of OPC. Higher-strength in the early stages is obtained by finely grinding the cement for higher fineness (specific surface area should not be less than 325 m²/kg) and increasing the proportion of C₃S.

Pavement construction may cause disruption to the traffic which will be inconvenient for the public. Therefore, speedy construction of pavement is necessary. Hence, for road pavements, the cement generally used is rapid hardening cement as it attains strength at a comparatively faster rate.
