Rheological Behavior of Fresh Cement Asphalt Mortar
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 composite material with cement and asphalt emulsion and acts as a cushion layer in the structure of slab track. The workability and homogeneity quality of fresh CA mortar is governed by its rheological behavior. Influences of cement type, emulsified asphalt type and superplasticizer dosages on the rheological parameters were analyzed by means of a rheometer. The rheological model was also explored. The results show that the CA mortar is a non Newtonian fluid and it shows thixotropic flow behaviour. The fresh CA mortar behavior is better described by the Herschel-Bulkley model. From the point of thixotropic behavior, the cement C-3 and emulsion A-1 may be beneficial for higher static and dynamic segregation resistance.
