The study is carried out based on a post-grouting method for pre-stressed prefabricated road design and construction to improve the level of highway engineering assembly construction in China.Further,the study on the aspects of assembly road structure innovation design,optimization of process flow,quality control,improvement of structural durability,shortening of the construction period,environmental protection,and promotion of industry transformation and development,etc.,a technical system of prefabricated road structure based on the staggered cross-section is established after grouting process,which adopts the technical scheme of vertical and horizontal two-way latticed beam design,two-way cross-section prestress,overlay plate inverted support process,post-grouting method closure,and follows the principle of modular design,segmented hoisting,two-way prestressed tension and closure,and post-grouting construction as a whole.The technical scheme is proven by experts and is feasible and valid,which is of significant application value to promote highway engineering assembly construction in China.
