LARGE VARIATIONS IN STRAIN ON ROADS BY LORRIES

SUURIA EROJA KUORMA-AUTOJEN TIESTOLLE AIHEUTTAMISSA RASITUKSISSA

The volume of strain conveyed from the vehicle to the road is affected by the structure of the axle system, type of tyres and their pressure, and naturally by the weight carried on the axles. In addition, there are a number of factors not yet included in the calculations. In summer 1982 the National Board of Public Roads and Waterways weighed about 2000 lorries and in spring 1984 about 4000 lorries. The AASHT formulae were applied to these results in order to obtain the strain applied to roads as a function of total weight. The volume of lorry traffic has remained almost constant during the last ten years. On the other hand the internal structure of lorry traffic has changed essentially as the proportion of heavy lorries is growing all the time. (TRRL)
