Four triangle reinforced concrete cantilever beams are designed as main supports of the bow to bear weight from secondary beams and boards, thus a super-long and overweight cantilever structure is builtup.According to bearing characteristics,construction conditions of the cantilever structure are rationally defined under premise of keeping safety and stability of the system.At the same time,position of section steel and steel pipes is used for large and high formwork. Monitoring results during construction process indicates that the technical scheme is reasonable and the structure is safe.

The physical quality of pumped cement emulsified asphalt mortar as the filing layer on site also met the requirements. Therefore， the pumping technique was proved to be suitable for the rapid large-scale construction of cement emulsified asphalt in ballastless track. Key words;emulsification; asphalts; pum...
