Material for preparing semi-flexible fluorescent pavement, and application method thereof

Abstract

The invention relates to a material for preparing a semi-flexible fluorescent pavement, and an application method there. The material comprises, by weight, 70-80% of an asphalt mixture as a parent material and 20-30% of fluorescent concrete mortar as a matrix material; the asphalt mixture is prepared from, by weight, 1 to 2 parts of SBS modified asphalt, 4 to 5 parts of coarse aggregate, 0.4 to 0.9 part of fine aggregate, 0.3 to 0.5 part of limestone mineral powder and 0.01 to 0.02 part of high-viscosity modified additive; the coarse aggregate is basalt with the particle size of 13.2-16 mm, and the fine aggregate is natural sand with the particle size of 4.5-9 mm; and the fluorescent concrete mortar comprises, by weight, 0.6 to 1.6 parts of white Portland cement, 0.2 to 0.4 part of super-fine sand, 0.1 to 0.2 part of a water reducing agent, 0.05 to 0.1 part of fly ash, 0.2 to 0.3 part of yellow-green fluorescent stone particles, 0.2 to 0.4 part of glass beads, 0.4 to 0.8 part of water,0 to 0.4 part of an SD emulsion and 0.01 to 0.04 part of polyvinyl alcohol. The pavement material has a photoluminescence function, and is high in luminous intensity, long in luminous time, good in pavement skid resistance, high in durability and high in pavement overall strength.

Description

technical field [0001] The invention belongs to the technical field of the composition of cement and asphalt materials, and in particular relates to a material for preparing a semi-flexible fluorescent pavement and an application method. Background technique [0002] With the rapid development of my country's economy and the increasing abundance of material life, the urban landscape environment has also been greatly developed. Under this background, city builders put forward the important concept of using iconic landscapes to show the city's style.

AI Technical Summary

Problems solved by technology

[0004] At present, there have been some studies on fluorescent pavement technology, but the application of these technologies has certain limitations:

[0006] Since some fluorescent stones or phosphors are added to the existing fluorescent road surface research and development materials, some traditional road materials are replaced accordingly, and in order to ensure that the fluorescent substances need to absorb light independently, translucent or transparent materials are selected as the matrix , so the strength of the material itself is greatly reduced, unable to meet the strength and bearing capacity requirements of vehicle roads, and can only be applied to landscape roads or pedestrian walkways. Due to insufficient material strength, the scope of use of fluorescent pavement is limited.

[0007] (2) Insufficient skid resistance of luminous pavement

[0008] Because fluorescent pavements are generally made of composite luminescent materials, traditional pavement materials cannot meet the luminous requirements, so other road performances are usually lost in order to obtain self-luminous effects

At present, the luminescent pavement mainly uses cement and polymer composite luminescent materials as the research subject, and the formed pavement surface has insufficient anti-skid performance, which seriously affects driving safety.
