Road surface noctilucent coating and construction method thereof

Abstract

The invention belongs to the field of functional pavement construction and maintenance, and particularly relates to a pavement noctilucent coating and a construction method thereof. The noctilucent coating comprises a binding material, a noctilucent material, an epoxy material and a solvent, wherein the binding material is a thermoplastic transparent binding material; the noctilucent material is a mixed material of aluminate or borate and rare earth elements; the epoxy material is a mixed material of epoxy resin and an epoxy curing agent; the solvent is a diluent; the preparation method of the noctilucent coating comprises the following steps: mixing the emulsified thermoplastic transparent binder with the noctilucent material, adding the solvent, sequentially adding the epoxy material, and uniformly mixing. The noctilucent paint can be suitable for pavements with early diseases, and on one hand, the noctilucent paint meets the requirements of noctilucent performance and pavement performance of the pavements; on the other hand, pavement regeneration is achieved, and pavement service life is prolonged.

Description

technical field [0001] The invention belongs to the field of functional pavement construction and maintenance, and in particular relates to a pavement luminous paint and a construction method thereof. Background technique [0002] In recent years, with the development of my country's economic construction, a large number of various functional pavement constructions have appeared. As one of the important technologies, luminous pavement has been rapidly researched and developed. It is found in research and practice that luminous pavement It has significant advantages in indicating traffic, guiding people flow, and aesthetics, and has broad application prospects in the field of road functional paving.

AI Technical Summary

Problems solved by technology

[0003] In the construction of luminous pavement, there are mainly two technical solutions: luminous coating and full-thick luminous pavement. The full-thick luminous pavement is to mix luminous materials (fluorescent stone or luminous powder) into the pavement material, or by mixing The luminous material is spread on the surface of the new road, and then the pavement is formed by rolling. The pavement performance is good, but the luminous performance of the road surface is poor, and it is mainly used for the newly built luminous pavement; the luminous coating is mainly made of resin materials and luminous Materials are mixed, and then painted on the road surface to form a luminous pavement. This technology has a better luminous effect, but due to the use of resin materials, the strength is high, and there is a difference in temperature shrinkage and deformation from the original asphalt pavement or cement pavement. The luminous coating is different from the original There is a long-term problem of interlayer bonding on the pavement, and it is prone to overall delamination. At the same time, due to the use of resin materials as the matrix, the coating is prone to temperature shrinkage and cracking.

[0004] At the same time, the current luminous pavement mainly adopts the method of new construction or coating when the performance and quality of the original pavement are still good. When there is a certain degree of performance degradation or micro-disease on the pavement, the original pavement needs to be milled before construction. It restricts the application of luminous pavement, and is not conducive to saving costs and improving resource utilization
