ESTIMATING THE SHOCK ENVIRONMENT ENCOUNTERED DURING TRANSPORTATION OVER PUBLIC ROADS

The report describes an attempt to specify the distribution of shocks to packages during transportation over public roads. The method makes use of data collected in local government offices for road maintenance purposes. The main cause of discrete irregularities in the surface of an existing road were frost damage, subsidence and openings made by public utilities. The author discusses the current maintenance procedure and its effect on the road surface. An expression is derived for the incidence rate of all defects including manhole covers for trunk and secondary roads. Tables are given to show the distribution of patches by area, the period of temporary repair and the intervals between treatments. The total annual repairs per mile of road undertaken by selection of five counties in the years 1968 to 1972 is given. The damaging effect of public roads is proposed in equivalent terms to that of the well defined Belgian pave. Equivalent exposure times on the nel transportation simulator or "bouncer" are derived for pave, trunk and secondary roads. /TRRL/
