PHASE II REPORT - Caltrans

APPENDIX C RESULTS OF RUGGEDNESS AMT TESTING
Mix 5 was used for performing the AMT ruggedness tests. The target optimized proportions for
M5 were 10% emulsion, 8% water, 0% liquid additive, and 0.5% type 2 cement. There were six
conditions which were adjusted for evaluation. The room temperature used was either 73.4°F
(23°C) or 80.6°F (27°C). The humidity condition used was either 40% or 60%. The emulsion
content used was either 8% or 12%. The liquid additive used was either 0% or 0.1%. The
mineral filler proportion used was either 0% or 1%.
The AMT data for the trials are contained in Table C.1 and the traces fro the trials are illustrated
in Figures C.1 through C.4..
