Abstract: In China Railway Track System II, the bonding of a cement asphalt mortar (CA mortar) layer to concrete slabs is a decisive factor for its durability and serviceability. In this study, the interfacial bonding strength between ...

Abstract: Two types of polymer latexes and one expansive agent were employed to investigate their effects on the resistance of cement asphalt (CA) pastes to sulfuric acid. Mercury intrusion porosimetry, a thermogravimetric analysis, ...
