Performance of Polymer Modified Chip Seals
The purpose of the study was to construct a full-scale test pavement using binders consisting of two sources of polymer modified high-float asphalt emulsion and one control high-float emulsion. Aggregates used varied from clean, high quality materials to marginally dirty materials. All materials were placed at rates appropriate for the existing pavement surface conditions and aggregate properties. Emulsions were applied from two pressure distributors equipped with standard and variable rate nozzles such that effect of lower emulsion application rates in the wheel paths could be observed. Field and laboratory Vialit tests were conducted during the experiment and suggestions are presented for improvement to the recommended procedure for obtaining repeatable test results.
