The Ministry of Transportation in Ontario , Canada (Rogers , C .A . , et al , , 1991 ) and the National Center for Asphalt Technology at Auburn University (Kandhal , P .S . , et al . , 1998 ) have performed research studies and have concluded that the Micro -Deval test provides a better correlation between aggregate durability than any other test currently in use . The MSS and the Micro -Deval test procedures were compared in terms of single and multiple laboratory precision .
The purpose of this study is to perform the statistical analyses that will be used to determine if a relationship can be found between the two tests so that TxDOT may adopt the Micro -Deval as a suitable alternative to the MSS procedure . Also , a statistical analysis will be performed to determine whether a relationship can be found between the Micro -Deval and Wet Ball Mill procedures . Based on the results from this study , appropriate specification limits will be proposed and recommendations presented concerning the implementation of the Micro -Deval test , for use by the Texas Department of Transportation . |
