Some observations made to check the possible use of the impact soil tester as a compaction control device for bituminous concrete mixes

Results of limited field experiments which were conducted to evaluate an impact soil tester for the control of the compaction of bituminous concrete mixes are presented. The experiments were associated with field trials involving a granulated rubber - bituminous concrete mix and a standard Country Roads Board (CRB, Victoria) bituminous concrete mix. It was observed that the type of bituminous concrete as well as its temperature at the time of testing had a significant effect on the impact meter readings obtained. By considering these effects it was possible to assess the variation in compactive effort that had been applied to the area of bituminous concrete laid. Impact values for the standard CRB bituminous concrete mix at normal in service road temperatures were higher than for normal unbound granular basecourses; however lower values were obtained for the rubber - bituminous concrete mixes. The meter also proved sensitive enough to detect the physical effects of daily temperature fluctuations in the bituminous mixes examined (a).
