Limiting the cracking of MCE mixtures used in base layers

Abstract

The subject of the analysis conducted in the article are mineral-cement-emulsion (MCE) mixtures containing reclaimed asphalt pavement (RAP). The mixtures contain innovative road binders based on cement-dusty by-products (UCPP). These binders, used instead of conventional cement, can reduce the stiffness of the resulting conglomerate, which will reduce thermal cracking in the road pavement base layers. UCPP binders can also contribute to the decarbonization of the MCE mixture production process. The conducted research demonstrated a significant effect of UCPP binders on the mechanical properties of recycled MCE mixtures. Crack propagation was analyzed using the SCB and UTST methods. As a result of the research, the binders were selected which most effectively limited cracking and its growth rate. These analyses contribute to a detailed understanding of the effective use problem of MCE mixtures with reclaimed asphalt in road pavement construction.
