Municipal road markings are the “lifeline” of urban traffic safety, and the reflectivity value directly determines the visibility of markings at night and in rainy and foggy weather. Insufficient reflection of hot-melt markings not only affects the acceptance rate, but also poses significant safety hazards. TOP ROAD Transportation Technology Co., Ltd. has been deeply involved in the field of road marking for 30 years. We have developed a high reverse thermal fusion system for complex working conditions of municipal roads, and solved the problem of reflection attenuation with scientific solutions to help engineering teams create “all-weather visible” safety markings.
1、 The three main causes of low reflectance values: precise targeting of problem targets
The unique challenges of the municipal environment have exacerbated the degradation of reflective performance:
Uncontrolled settlement of glass beads: Excessive material temperature causes glass beads to sink into the bottom layer of the coating, while insufficient material temperature prevents effective embedding; Vehicle crushing frequency is high, and the glass beads on the acceleration surface fall off.
High concealment of base pollution: urban road oil pollution (catering street) and dust (construction belt) cover the surface of the marking line, forming a reflective barrier; Newly laid asphalt spills and pollutes the edge of the marking line.
Mismatch between materials and scenes: Ordinary glass beads have insufficient stain resistance, and reflection drops sharply in rainy and foggy days; Low resin content and weak anchoring force of glass beads in low-priced coatings.
TOP ROAD breakthrough logic: “Glass bead coating substrate” three in one collaborative optimization, building a long-term reflective system.

2、 Material Upgrade: The Genetic Revolution of Reflex Values
Scientific selection of glass beads:
High refractive index bead core (1.7+): Breaking through the reflective limit of ordinary glass beads, improving the penetration power on rainy nights;
Composite coating technology: surface titanium dioxide coating enhances anti fouling properties and slows down oil adhesion;
Particle size gradient ratio: Large particle size beads (0.8-1.2mm) provide basic reflection, while small particle size beads (0.4-0.6mm) fill gaps to improve uniformity.
Innovation in coating formula:
High whiteness resin substrate: enhances the reflectivity of the base color and amplifies the reflective efficiency of glass beads;
Micro porous curing technology: The coating surface forms a honeycomb structure and mechanically locks glass beads;
Oil repellent additive: Resists oil pollution infiltration in catering areas and maintains surface cleanliness.
3、 Construction precision control: the birth site of retroreflection value
Accurate temperature management:
Melting temperature: lower than asphalt pavement to prevent excessive settlement of glass beads caused by high temperature;
Ground temperature: Real time monitoring by infrared thermometer to ensure that the flowability of the coating matches the speed of glass bead embedding.
Revolution in Glass Bead Spreading Technology:
Dual channel spreading system: The bottom layer is pre mixed with glass beads to provide basic reflection, and the surface is sprinkled with specialized beads to enhance instant reflection;
Windproof and stable flow cover: solves the problem of crosswind interference between urban buildings and ensures uniform distribution.
Base defense works:
Oil pollution sniper plan: Fire gun baking+specialized cleaning agent to remove stubborn oil stains;
Anti oil overflow primer: Apply oil resistant primer on new asphalt pavement to cut off pollution sources.
4、 Long term maintenance: lifecycle management of reflectance values
Active defense during the acceptance period:
Golden 72 hour maintenance: Cover with breathable protective film before opening to traffic to prevent tires from adhering to glass beads;
Pre check of reflectance value: Simulate vehicle inspection 24 hours after construction to detect dark areas in advance.
Intelligent maintenance during operation:
Strengthening of high wear areas: adding glass bead re scattering points in front of intersections;
Pollution emergency response: Special marking cleaning agent to restore surface transparency.
