Jun 01 2006 therefore to account for these errors regression analyses were performed to calibrate or correct thecorelok methodtest results to associated t 8485 values "calibrationof thecorelok methodfordeterminationof missouri aggregate specific gravities" by david newton richardson
Thismethodmay be used as an alternative to the conventional rice test for thedeterminationof maximum specific gravity of loose asphalt mixtures thecorelok test can be completed in seven minutes with minimal exposure to water eliminating the need for a lengthy dry backmethod
Thismethodmay be used as an alternative to the conventional rice test for thedeterminationof maximum specific density of loose asphalt mixtures thecorelok test can be completed in seven minutes with minimal exposure to water eliminating the need for a lengthy dry backmethod
Calibration of the corelok method for determinationofmissouri aggregatespecific gravities the current aashto procedures fordeterminationof specific gravity and absorption of coarse and fine aggregates are time consuming and the repeatability is less than generally desired
Based on this observation we developed a twostep calibration method that overcomes said limitations the first step is an external calibration with a highorder polynomial function used for the determination of the relation between mz and t2 and the second step is a firstorder internal correction for sample positiondependent errors
Thismethodmay be used as an alternative to the conventional rice test for thedeterminationof maximum specific density of loose asphalt mixtures thecorelok test can be completed in seven minutes with minimal exposure to water eliminating the need for a lengthy dry backmethod
Thecorelokprocedure for fine aggregate was the only procedure that produced statistically similar results to the aashto procedures there was a high correlation between thecorelokprocedures for bulk specific gravity and aashto t84 and t85 adjustments to the algorithm used by thecorelokprocedure could produce more acceptable results
Ggau calculation were performed for oxides of ti v mo and ce with the objective of establishing the best value of the parameter ueff to use in order to match the calculated reduction and oxidation energies of each oxide with experimental values in each case the reaction involved the hydrogen reduction of an oxide to its next lower oxide and the formation of water our calculations show
