ABSTRACT: Geosynthetics have been widely used to enhance the performance of roadways in seasonal frost regions, but their effectiveness against freeze-thaw induced deterioration in pavements is not well appreciated. This study introduces full-scale experiments on the freeze-thaw (F-T) performance of geosynthetics-stabilized bases in a flexible pavement located in Sturgeon County, Alberta. The test was composed of three sections with the base courses stabilized by geocomposites and two types of novel polymeric alloy (NPA) geocells (100-mm Type-D and 150-mm Type-C), respectively. The pavement sections were fully instrumented with earth pressure cells, moisture sensors, and thermal sensors. Plate loading tests and trafficking tests were performed on each section before the ground was frozen in November 2022, and will be conducted after each seasonal F-T cycle. This paper presents the first stage of the experimental study, focusing on the instrumentation in the road sections and plate loading and trafficking tests. Some preliminary observations on the performance of the three test sections are discussed.
