COMMERCIAL TRAFFIC AND ROAD PAVEMENTS

The primary purpose of a road network is to facilitate the movement of commercial vehicles, and the author notes the effects which the heavier and larger loads being carried since the increase in fuel costs, are having on road structures. It is suggested that policy should be to provide and improve progressively the roads as need arises. Maintenance will be required because of foundation movements and the need to restore surface resistance to skidding. Pavement design according to the recommendations of Road Note no 29 is discussed and reference made to the difficulty in forecasting traffic intensities. The performance of various UK motorways is considered with reference to Road Note no 29, and reasons for early failures are presented. Statistics available indicate increasing number of axles per commercial vehicle and consequent greater damaging effect on road pavements. A progressive strengthening programme built into the pavement design is suggested to provide for increasing traffic intensity. Stricter control is advocated for overloaded vehicles and notifiable heavy loads. (TRRL)
