A kind of material and application method for preparing semi-flexible fluorescent pavement

technical field

The invention belongs to the technical field of compositions of cement and asphalt materials, and particularly relates to a material and an application method for preparing semi-flexible fluorescent pavement.

Background technique

With the rapid development of my country's economy and the increasing enrichment of material life, the urban landscape environment has also been greatly developed. Under this background, urban builders have put forward the important concept of using iconic landscapes to show the city's style. ("Research on the Iconic Improvement of Urban Landscape Roads", Master's Thesis, Northeast Forestry University, 2014, abstract, published on April 1, 2014; "Theory and Practice Exploration Research on Landscape Road Pavement", Northwest A&F University Master's thesis, 2012, abstract, published on May 1, 2012).

A functional pavement that can not only meet the needs of highway lighting at night, but also save energy has become a research hotspot in today's road engineering, and fluorescent pavement materials are such a new type of luminescent material. Fluorescent pavement is mainly used in the decoration of colored urban walkway system, warning and lighting on special pavements such as wetland parks and mountain roads, which can greatly reduce the contrast of light and light, extend the night vision distance of pedestrians or drivers, and ensure travel safety. Satisfying the landscape effect can save a lot of electric energy and reduce operating costs ("On the status and development of luminous pavement", Xu Yijia, Jiangxi Building Materials, No. 2, 2017, pp. 168 and 169, published on January 30, 2017; "Research and Application of Self-luminous Coatings for Long Afterglow Pavement", Xu Jianhui, Highway Traffic Technology, Issue 6, 2017, Page 15, published on December 25, 2017; Application”, Wang Xiuyuan, Urban Roads, Bridges and Flood Control, Issue 3, 2018, p. 220, published on March 15, 2017)

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

(1) Material strength is limited

Since some fluorescent stone or fluorescent powder is added to the existing fluorescent road research and development materials, some traditional road materials are replaced accordingly, and in order to ensure that fluorescent substances need to absorb light independently, a translucent or transparent material is selected as the matrix. Therefore, the strength of the material itself is greatly reduced, which cannot meet the strength and bearing capacity requirements of vehicle roads, and can only be applied to landscape roads or pedestrian walkways.

(2) Insufficient skid resistance of luminous pavement

Since the fluorescent pavement is generally made of composite luminescent materials, the traditional pavement materials cannot meet the luminous requirements, so other road performances are usually lost in order to obtain the self-luminous efficacy. At present, luminous pavement mainly uses cement and polymer compound luminescent material as the main research body, but the formed road surface has insufficient anti-skid performance, which seriously affects the driving safety.
