THE USE OF A DATA BANK FOR AXLE LOAD POLICY PLANNING AND STRENGTHENING PURPOSE

A general bearing capacity register has been established for the entire main road network in Norway, comprising 25000 km. Both the summer bearing capacity (based on deflection measurements) and the spring thaw bearing capacity (based on sampling from trial holes) is given. Deflection measurements have been taken every 50 M, while sampling was carried out at 500 M intervals. At the same time other road data were collected (surface width, shoulder width, surface failures, drainage condition etc). The total costs amounted to $120-160 per km, the deflection measurements being responsible for approx 25% of this (1976). For each of the 18 districts the results are summarized in a detailed printout for each km of road with deflection and sampling data including strengthening requirements for 8 and 10 tons axle loads; a graphical presentation of the same; and summary data for each road. Many districts are now establishing bearing capacity registers also for the secondary road network (31000 km), but only deflection measurements, giving the summer bearing capacity, are taken.
