Abstract:For the study of asphalt foaming characteristics and the performance of cold recycled mixture, three kinds of asphalt, three foaming temperature and three foaming water consumption were used to test the asphalt foaming in this paper. Under the best foaming condition of asphalt,  the water stability and low temperature performance of the cold recycled mixture were studied. The results showed that foam asphalt could be obtained by choosing the proper bitumen, foaming temperature and foaming water consumption, and the foamed asphalt cold recycled mixture had good road and mechanical properties.
