CA MORTAR CONSTRUCTION OF THE TRIAL SECTION OF WUHAN-GUANGZHOU RAILWAY PASSENGER DEDICATED LINE

摘要

A five-step controlling method in the construction of cement-emulsified asphalt mortar (CA mortar) at Wuhan-Guangzhou Railway Passenger Dedicated Line (WGRPDL) is presented. The gathered data of the temperature, the construction rate, the fluidity and the air content of CA mortar are also analyzed. Results showed that the controlling method was effective in the construction management and the temperature had serious impact on the construction rate. Results also showed that the fluidity and air content of CA mortar almost had the same relative standard deviation; moreover, the two factors seemed to have linear relationships.
