by failure of the concrete slab but by problems with the materials beneath the slab. These problems can include poor drainage, unstable or nonuniform materials, or poor compac-tion. Adequate preparation of the roadbed—the subgrade, sub-base, and base—is essential for a strong, durable concrete pavement system.

Concrete pavements require a uniform level of support for good long-term performance. Abrupt changes in support can lead to cracking, poor ride quality and other pavement distresses. Concrete pavements do not benefit significantly from very strong support layers.
Thus cement concrete roads should be the obvious choice in future road programmes. Besides the easy available of cement, concrete roads have a long life and are practically maintenance-free. Another major advantage of concrete roads is the savings in fuel by commercial vehicles to an extent of 14-20%.
