Hot melt marking construction on highways is a must see! 90% of construction teams make these mistakes

In the field of highway marking construction, seemingly simple operations conceal many technical details, and many common construction problems often stem from overlooked fundamental errors. TOP ROAD Transportation Technology Co., Ltd., as a professional supplier deeply involved in the road marking industry for many years, has summarized several major mistakes that construction teams are prone to make in the process of serving thousands of marking projects across the country. This article will reveal these common construction misconceptions and provide professional solutions to help your construction team avoid these “pitfalls”, significantly improving the quality and durability of the marking project.

Error 1: Neglecting road surface pretreatment

The first mistake that many construction teams are prone to make is underestimating road surface preparation work. The technical team of TOP ROAD Transportation Technology found during on-site inspections that nearly half of the problem of marking detachment is due to insufficient road surface cleaning. Dust, oil, moisture and other pollutants can form an isolation layer, seriously affecting the bonding strength between the marking and the road surface.

The correct approach is: TOP ROAD recommends using a two-step pretreatment method of “cleaning+activation”. Firstly, professional cleaning equipment should be used to thoroughly remove impurities from the road surface. For sections with severe oil pollution, specialized cleaning agents should also be used; Secondly, before marking the road surface, select a suitable primer based on the road surface material to enhance the interfacial adhesion. This standardized preprocessing process can significantly improve the adhesion performance and service life of markings.

Error 2: Improper temperature control

Temperature control is a key factor in hot melt marking construction, but it is also one of the technical points that construction teams often make mistakes in. TOP ROAD Transportation Technology found during quality follow-up that many issues with blistering, poor leveling, and insufficient glass bead embedding on the markings are directly related to improper temperature control.

Professional temperature management should achieve: TOP ROAD recommends using the “three-stage” temperature control method. The material melting stage adopts a gradual heating strategy to avoid local overheating; Maintain a stable temperature range during the insulation stage to ensure uniform material properties; During construction, real-time adjustments should be made according to the ambient temperature to ensure optimal working viscosity. At the same time, temperature detection equipment should be calibrated regularly to avoid temperature loss due to instrument errors.

Error 3: Improper spreading of glass beads

The spreading of glass beads may seem simple, but in reality, it requires a high level of technical expertise, which can be easily handled hastily during construction. According to market research by TOP ROAD Transportation Technology, over 80% of cases where the reflective effect does not meet the standard at night are related to improper distribution of glass beads.

Standard glass bead spreading should be noted: TOP ROAD recommends using the “three synchronous” spreading method. The spreading time should be strictly synchronized with the marking to ensure that the glass beads are embedded at an appropriate depth; The spreading amount should be precisely controlled according to the type of marking and traffic flow; The uniformity of spreading should be ensured by professional equipment. At the same time, high-quality glass beads that meet national standards should be selected to avoid using products that are damp or have uneven particle sizes.

Error 4: Neglecting the influence of environmental factors

Many construction teams often overlook the impact of environmental factors when developing construction plans, which is also an important reason for the quality problems of marking lines. The project analysis of TOP ROAD Transportation Technology shows that environmental factors such as seasonal changes, temperature differences between day and night, and air humidity directly affect the curing process and performance of markings.

Scientific construction arrangements should: TOP ROAD suggests establishing an environmental factor assessment mechanism. Before construction, monitor the environmental temperature and humidity to avoid extreme weather conditions; Adjust material formulas and construction techniques according to seasonal characteristics; In humid environments, specialized products should be selected and the curing time should be appropriately extended. These targeted adjustments can effectively reduce the impact of environmental factors on construction quality.
