Abstract:

The Federal Highway Administration (FHWA) is conducting an interlaboratory study to validate certain findings in the Strategic Highway Research Program (SHRP) C-343 report on alkali-silica reactivity. This paper reports the Virginia Transportation Research Council (VTRC) findings relative to the rapid immersion test (AASHTO TP 14). Tests were conducted examining the use of AASHTO TP 14 for evaluating the effectiveness of fly ash and to determine the necessary dosage of lithium hydroxide monohydrate (LiOH H₂O) to prevent excessive expansion resulting from alkali-silica reactivity (ASR). The results obtained are encouraging with respect to the use of the TP 14 test to evaluate the effectiveness of a particular fly ash with a particular aggregate; however, it does not appear to be suitable for determining (LiOH H₂O) dosage rates. A summary report incorporating the results of all participating laboratories will be issued by the FHWA..
