Abstract:

       We designed three different proportions of cementasphalt emulsion cold recycling mixtures by different mixing ratios of new aggregates and RAP. We also investigated the impacts of cement and RAP contents on their water stability. Results show that cement addition can improve their water stability, but optimum content exists. Their water stability reduces with the increase of RAP content.

Key words: cement, asphalt emulsion, cold recycling, proportion design, water stability
