Pavement Design - Use of mechanistic procedures for the design of a flexible pavement. Design parameters: Two lanes two-way road (one lane in each direction) Length of road: 2.0~3.0 km (Flexible) Direction factor: 0.5 Lane distribution factor: 1.00 NHVAG and ESA/HVAG should be calculated from the traffic distribution table.
