Constitutive relations for split cylinder tests on bituminous concrete
Abstract The scope of this progress report was to a determine the constitutive relations for asphaltic concrete using the split cylinder test for two percents of bitumen, and b. compare the results with uniaxial tensile data on asphaltic concrete to assess the suitability of the split cylinder test for routine material characterizations. A special digital computer routine was used to reduce the experimental data, develop the constitutive relations, and perform the statistical analysis. Using the procedures reported here, the split cylinder tests, compared with uniaxial tension tests, overestimated the strain at high rates of loading, underestimated at very low rates of loading, and the ultimate strain values for the two test methods were the same for a value of R of about 0.1%/min. The split cylinder test underestimated the ultimate tensile stress by about one-half an order of magnitude for all values of strain rate that would be used in highway work.
