The construction of road pavement with concrete seems very advantageous from technical point of view especially for heavy load transportations. However, the use of concrete pavement often results in higher initial cost in comparison to asphalt one though the service life of concrete road is generally longer.

The development of a commercial low cost hydraulic binder of adequate strength capacity will contribute to the reduction of the initial cost of concrete pavement.
