Preparation and Performance Study of Prefabricated Road Rigid Joint Materials for High Flow Vehicles
This article explores the mechanical properties,fatigue resistance,microstructure,and products of modified mortar through polymer modified cement-based materials,and investigates suitable joint filling materials for prefabricated pavements accommodating high flow vehicles.The research results show that the flexural and compressive strengths of rigid joint mortar at 28d meet the requirements for tensile stress of 0.3 MPa and compressive strength of M10-grade cement mortar for joint filling.This can quickly meet the requirements for traffic opening and reduce traffic interruption times.Additionally,the GIII rigid mortar exhibits fatigue deformation resistance up to 2 million cycles,remaining in the early and middle stages of compressive fatigue failure,which is sufficient for medium-traffic loads.The application of this type of mortar in prefabricated road slab engineering demonstrates excellent overall performance and cost-effectiveness.
