AbstractPrestressed duct grouting technology and quality assurance measures are the key factors to ensure the quality of bridge construction. Grouting materialsgrouting technology and quality testing were required very strict in the process of applying prestressed duct grouting technology. A highway prestressed duct grouting construction practice was introduced in this paper. Pressure test of the thick liquid material and related technical clarificaiton and technical trainingconstruction preparationgrouting technology were indruced, which can provide reference for similar projects.
