Abstract:Cement asphalt mortar (CA mortar) is the key component in the structure of Shinkansen slab track and serves as the elastic shock-absorber. CA mortar is a fluid mixture suitable for placing in structures without vibration. CA mortar development must ensure a good balance between fluidity and stability. Hydrophobically associating watersoluble polymers not only have the unique advantage of segregation resistance but also good properties of fluidity. The fluidity and segregation tests show that by adding hydropho… Show more
