The purpose of the study was to examine the usability of geopolymer materials for pavement pothole patching. The special focus of the study was on the use of materials in cold (5.. .-10°C) weather conditions, such as at the end of winter when the problems faced while conducting repairs are most serious. The influence of the chosen factors on the performance of the material was studied using the Taguchi design of experiments method. The experiment was conducted using 13 control factors, with special attention given to strength development and weather resistance characteristics. The results indicated that the magnesium phosphate material studied had good weather resistance, as a result of the low-grade reactive waste magnesia used. According to the results using bitumen as an additive and a high activator to magnesia ratio had a positive impact on the performance of the patching material. In addition, relations between the responses were analysed using structural equation modelling. According to the model, higher water demand indicated an increase in water absorption and further lowered water and freeze-thaw resistance.
