A novel prefabricated road base stands out for its high strength and rapid construction. The cost and difficulty of full-scale experiments are high, which poses obstacles to the mechanical behaviour analysis of prefabricated base asphalt pavements. This study employs small-scale model experiments to analyse the mechanical behaviour of the novel prefabricated base pavement. Firstly, a 1/4-scale experimental method of prefabricated base asphalt pavement based on the similarity theory was proposed and verified. Secondly, the mechanical properties of the prefabricated base pavement under various l...
