BEARING CAPACITY WITH STATIC PLATE LOADING AND ESTABLISHMENT OF DATABASE

BAERIGHETSMAETNING MED STATISK PLATTBELASTARE SAMT UPPRAETTANDE AV FUNKTIONSBANK

The new Swedish Road Standards specified in VAEG 94 are valid from August 1 1994. The standards described therein require that one must measure the bearing capacity with either Static Plate Loading or Isotope measurement. In this report have been measured the bearing capacity of several different surfaces and subgrade layers. In order to obtain a better interpretation of these measurements a database is constructed for bearing capacity measurements and material composition. It should be noted that none of the selected road sections have been tendered in accordance with VAEG 94. If the bearing capacity standards in VAEG 94 were to be applied at this point all the measurements would have to been rejected. In the opinion of the authors all the control surfaces fail due to a low bearing capacity in the subgrade layer. No other explanation for the lower values could be found. A low bearing capacity in the subgrade layer tends to make the standards specified in VAEG 94 unobtainable. To achieve these standards it is suggested a number of measures whereby the standard of the subgrade layer would be adjusted according to seasonal and material variations. One should perhaps confine production solely to the drier summer period in order to avoid wet subgrade layers. The bearing capacity standards of the subbase and base layers need further investigation, possibly these standards could even be withdrawn. One might consider having regulations governing only the materials, thicknesses and compaction of such layers. This is considered to be economically advantageous. (A)
