Effect of Particle Shape on The Behavior of Polymer-Improved Sandy Soil Used in Pavements Due to Freeze-Thaw Cycles
نویسندگان
چکیده
Freeze-thaw cycles have a significant negative effect on the engineering behaviour of soil in cold regions. In this study, compressive strength stabilized, poorly graded sandy used road pavement that was subjected to different freeze-thaw studied. Samples with three particle shapes were stabilized binder developed by mixing polyvinyl acetate (PVAc) and ethylene glycol monobutyl ether (EGBE). The PVAc/EGBE weight ratio 2:1, PVAc added at 1%, 2%, 3% dry soil, up ten evaluated. Results showed addition decreased optimum moisture content increased strength. An increase roundness results decrease magnitude but increases composite ductility. Changing shape from angular rounded resulted more than changing well-rounded. is most between first fourth freezing-thawing marginal tenth. increasing particles compensated percentages.
