The construction method of the road is started once the site is fully prepared. The concrete should be set in proper depth and for this purpose, 2.5 – 5 cm thick and 3 mtr long wooden sheeting should be applied.

The size of movement depends upon the change in temperature and the coefficient of thermal expansion o f concrete. The coefficient of thermal expansion of concrete is influenced largely by the coefficient of thermal expansion of the aggregates since the aggregate occupies 70-80% of the volume of the concrete.
