Abstract
1 General Provisions
1.0.1 This code is established to standardize the application of two-component road traffic markings in road engineering projects and to reduce environmental pollution.
Article Explanation:
According to the definition in the current standard GB5768.3, road traffic markings include pavement markings, vertical surface delineators, raised pavement markers, and outline markers. Currently, China primarily uses a two-component material system for applying the pavement marking sections. Therefore, in this regulation, "two-component road traffic markings" refer to traffic markings applied to the road surface using a two-component material system.
1.0.2 This regulation applies to the construction, reconstruction, expansion, and maintenance projects of highways and urban roads.
Article Explanation:
The application scenarios for road traffic markings include both highway projects and municipal roads. This regulation outlines specific technical requirements tailored to these two distinct application contexts, covering aspects such as construction guidelines and recommended design service life.
1.0.3 This procedure specifies the material, design, construction, and quality inspection requirements for MMA two-component road traffic markings.
Article Explanation:
According to domestic and international sources, line-marking coatings typically utilize two-component (or multi-component) systems, including MMA systems, polyurethane systems, polyurea systems, and epoxy systems, among others.
In the early 21st century, China began introducing two-component material systems from abroad. The "Road Marking Coatings" standard (JT/T 280-2004) officially incorporated two-component coatings into its system. However, due to uneven development in the research and application of different material systems as well as variations in construction equipment availability, the domestic market for two-component road markings currently remains dominated by MMA-based two-component coatings.
MMA (Methyl Methacrylate) is the English abbreviation for methyl methacrylate, an active monomer that serves as the foundational raw material for reactive acrylic resins. MMA resin is a composite material composed of various reactive monomers, including (methyl)acrylate groups. Under the action of a curing agent, the carbon-carbon double bonds undergo crosslinking reactions to form a film, resulting in coatings with excellent mechanical properties after curing. Road traffic markings prepared using MMA resin are classified as MMA two-component coatings. When these MMA two-component coatings are applied to create road markings, the resulting markings are known as MMA two-component road traffic markings, often referred to simply as MMA two-component markings in this standard.
European countries, represented by Germany and Switzerland, began using MMA two-component road markings as early as the 1970s, while the United States adopted the technology in the 1990s. Today, it is already widely used overseas. China introduced this technology in the early 21st century, and after more than 20 years of development, it is now extensively applied to both highways and urban roads domestically.
MMA resin goes by several names internationally, such as methacrylate resins, acrylic resins, cold plastic resins methacrylate, methyl methacrylate (MMA), and polymethyl methacrylate (PMMA). For convenience, this procedure will be referred to simply as MMA resin.
Solvent-based coatings do not use acrylic resins as part of this type of resin.
1.0.4 The application of two-component road marking materials for MMA shall, in addition to complying with the provisions of this regulation, also adhere to the current relevant national and industry standards.
Article Explanation:
Group standards are an important component of China's national standard system, effectively complementing both national and industry standards. The corresponding clauses in this regulation are all formulated on the basis of meeting current national and industry standards, while further clarifying and refining certain specific indicators and parameters.
