A Novel Method for Polymer Content Determination in Asphalt Binder and Emulsion

Modification of asphalt binder is a must to enhance the performance of asphalt binder. The objectives of this study are to develop an extensional deformation test method using a Sentmanat Extensional Rheometer (SER) fixture inside a Dynamic Shear Rheometer (DSR) and to investigate the relationship between different percentages of latex polymer and force ductility in polymer (latex) modified asphalt emulsion (PMAE) and polymer modified asphalt binder (PMAB). The sample geometry used in this study is 3 mm × 0.72 mm. Total twenty-four samples are tested by the SER where twelve samples are PMAE and twelve samples are PMAB. One neat binder PG 64-22 and one PMAE are used. 2%, 4% and 6% latex are mixed with PG 64-22 by a mechanical mixer and a high shear mixer for making PMAB. PMAEs are collected from the manufacture with 0%, 2.5%, 4% and 5.5% latex in it. Second peak elongation force, F2 is only obtained from the latex modified binders and emulsions. First peak elongation force, F1 has no linear correlation in case of PMAE and PMAB where F2 has a linear correlation with the percent of the polymer in the PMAE and PMAB with R2 values equal to 0.9934 and 0.9535 respectively indicating extensional deformation test with SER is very promising. Additionally, DSR temperature sweep test results and multiple stress creep recovery (MSCR) test results indicate that F2 is a better indicator of polymer content than rutting factor G*/sinδ and non-recoverable creep compliance, Jnr.
