Rapid hardening cement is used in the repair of roads & Blast furnace slag cement is used in the construction of road b/c road payment are constructed over soil and soil is generally rich in sulphates and BFSC has good resistance against sulphate attack.

** Low heat cement is used for massive works like dams, retaining walls, etc.
** Ordinary Portland Cement is used for general works except the area having sulphate attack(OPC is least resistant to Sulphate attack).

In road pavement we should use rapid hardening cement because road is a very busy line and we can't free road for long time so to open road for use quickly we use rapid hardening cement.

Rapid hardening is correct because the road is open to traffic in minimum days and it also have one day strength equal to 3 day strength of opc.

For road pavement - rapid hardening cement.
For massive concrete - low heat cement.
For canal lining or sever - portland slag cement.

Rapid Hardening cement is used for repairing works.
OPC is use for all new construction works.
So, OPC is correct answer.
OPC is use for all new construction works.

Rapair work - rapid hardening cement.
Road construction- low heat cement (resistance to sulphate and chemical attack).

I think blast furnance cement use because pavement laid on soil. Sulphate present in soil so this cement protect.
