DEVELOPMENT OF 3D CONCRETE PRODUCTION TECHNOLOGY FOR APPLICATION OF ROAD CONSTRUCTION

In recent years, concrete has been commonly used in the construction of many road works. However, because of the poor tensile and bending ability, temperature fluctuation, and other overload factors, the concrete structure is often cracked, broken, or damaged during use. The solutions to increase the load capacity include increasing the pavement thickness, the concrete grade, treating the road well, etc. Nonetheless, due to the limit of conventional techniques, the enhancement was unremarkable. Therefore, it is necessary to develop new technology to overcome these difficulties. Since the creation of a model using the wire mesh reinforcement for concrete pavements, the load capacity of that system was comparably improved [1]. Later, the applications of that idea for civil construction hooked many scientists up [2-6]. However, because the used system was not a three-dimensional structure, the efficiency increased insufficiently. In Vietnam, many engineers and scientists also proposed solutions to overcome these issues [7-13]. Thus, this work contributes some research results related to the development of 3D wire mesh technology as reinforcement for 3D concrete pavement and attempt at road construction and other transportation structures in Vietnam
