Composition and Structure of Flexible Pavements. Flexible pavements support loads through bearing rather than flexural action. They comprise several layers of carefully selected materials designed to gradually distribute loads from the pavement surface to the layers underneath.
The materials required to construct a road depends upon the type of road (highway, State highway, MDR, Village roads etc.), climate in which it need to stand, loads coming on it, part of country in which it is to be constructed, availability of materials locally, economy of road etc.
3. Experiences from China RIOH In 1978, Empirical-Mechanical asphalt pavement design system was established in China. In 1997, The semi-rigid base asphalt pavement was normally appointed as typical structure for high class highway design and construction.
Design CBR of the subgrade is found to be much less than that of the borrow materials and it is incorrect to use CBR of the borrow material alone as the CBR of the subgrade. ii) Charts are presented for evaluation of design (equivalent / effective) CBR value of subgrade for various combinations of native and borrow soils.
Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway engineering became prominent towards the latter half of the 20th Century after World War II.
