LOW TEMPERATURE CHARACTERISTICS OF BITUMEN POLYMER BINDERS AT CYCLIC FROSTING AND DEFROSTING
Journal Title: Вестник Харьковского национального автомобильно-дорожного университета - Year 2017, Vol 79, Issue
Abstract
The results for determining rheological characteristics (stiffness and relaxation rate) of 8 bitumen polymer binders in their initial condition and after 25 cycles of frosting-defrosting at the temperatures of –24 °С, –30 °С and –36 °С using the bending beam rheometer (BBR) are presented. It has been established that the stiffness of binders increases considerably with the temperature decrease.
