1. In the handling of seriflux injection into crosswise crevice on bituminous pavement in industrial development zone of Zhangzhou, FWD is used to examine and analyse the handling effect.

2. The organic acid in seriflux was mainly lactic acid which developed by the fermentation of lactobacillus, and lactobacillus mainly came from environmental microbial groups.

3. When water glass seriflux as chemistry injection material, its kinetic viscosity is varying with time, so the process of seriflux permeating in the sand is complicated.

4. The reasons of the turbidity produced in production or in shelf period were analyzed. The turbidity was induced mainly by inorganic salt in seriflux and the ethyl fatty acid in brut liquor.

5. Optimal parameters for various factors in yellows'eriflux and methods of use of esterized seriflux in practical production were also explored.
