New Road Marking Standards Drive Industry Upgrades: Heavsty Solutions for Precision Road Renovation

Implementing new national standards and improving marking quality in the ADAS era - Heavsty marking equipment provides precise construction support for the renovation and renovation of existing roads

In May 2026, the mandatory national standard GB 5768.3-2025 "Road Traffic Signs and Markings Part 3: Road Traffic Markings" will be fully implemented, replacing the 2009 version of the standard that has been in use for 16 years. The scope of application has been expanded from "motor vehicles" to "vehicles", the edge line of the left lane has been changed to yellow, and the markings of the stop and dedicated lanes have been updated synchronously - a round of deterministic marking transformation demand has emerged for existing roads nationwide. At the same time, ADAS (Advanced Driver Assistance Systems) has put forward new requirements for the "machine readability" of lane markings. Heavsty, a professional manufacturer of marking facilities, responded to the market upgrade of the "policy+technology" dual wheel drive with a passenger driven marking machine.

Industry pain points: why this round of transformation must be done

At the policy level, compliance is a rigid expenditure. GB 5768.3-2025 adds regulations on the classification of longitudinal marking forms and lane changing lines, and includes non motorized vehicles in the scope of application of the standard. This means that a large number of existing road markings are not in compliance with the new regulations and need to be redrawn - this is a deterministic requirement of 'do it or violate it', rather than an optional requirement.

On a technical level, the value of markings has been redefined. The empirical study (report number CT-2326-F-23-5) released by the Connecticut Department of Transportation in 2024 showed that after redrawing high-quality markings, the success rate of lane detection for 8 different brands of ADAS vehicles significantly improved, and the improvement effect was consistent across brands. Markings are no longer just safety facilities for people to see, but also the "physical sensor interface" of the auto drive system. Clear, continuous, and high contrast markings directly determine whether L2+vehicles can operate stably.

At the construction level, the contradiction between manpower and precision has intensified. The labor cost of road construction continues to rise, and manual layout errors are difficult to meet the requirements of millimeter level markings; 'Saving manpower, time, and one-time molding' has become the top priority for contractor procurement.

Heavsty Solution: Ride on Marking Equipment Family

Regarding the three major pain points mentioned above, Heavsty provides a product line of ride on marking machines covering both hot melt and cold spray processes, allowing construction teams to "trade equipment for manpower and precision for rework".

HW-18CS Vehicle-Mounted Cold Spray Line Marking Machine

3A Multifunctional Hot Melt Marking Machine

Applicable scenarios

Urban road stock renovation: non motorized vehicle lane marking supplementation, yellow edge line modification - flexible and efficient cold spraying equipment;

Highways and trunk highways: hot melt marking re paving, lane changing line drawing - one-time molding using a ride on hot melt machine;

Parking facilities and parks: renovation of parking spaces and guide lines - small batch fast turnover;

The combination project of "removing lines first, then marking lines": the old lines are cleared and redrawn synchronously, and the Heavsty high-pressure water wire removal machine and marking machine are delivered in combination.

Frequently Asked Questions (FAQ)

Q1: What new requirements does the new national standard have for marking equipment? The new national standard has updated the classification of marking lines, colors (such as yellow edge lines), and line type settings. The most direct requirement for the equipment side is that the line type can be flexibly switched and the layout accuracy can be controlled. The Heavsty ride on device supports GPS/GNSS assisted positioning and multi line construction, and can quickly adapt to new line types.

Q2: How to choose between cold spray and hot melt marking machines? Cold spray is suitable for ambient temperature coatings and small batch fast turnover projects (urban roads, non motorized vehicle lanes); Hot melt is suitable for high-grade highways with high durability requirements, large traffic volume, and nighttime reflection. Heavsty has two product lines covering two processes, which can be purchased according to project combinations.

Q3: How does the 18CS pressure system ensure the quality of the markings? The 18CS system has a working pressure of 10-15 MPa and an adjustable construction pressure of 80-95 bar. It is equipped with a stabilizing energy storage tank that continuously buffers pressure fluctuations, ensuring no pressure fluctuations throughout the spraying process. Constant pressure means that the coating atomization is stable, the film thickness is uniform, and the line shape is coherent, eliminating interruptions and uneven thickness caused by pressure fluctuations; For ADAS detection, clear and coherent markings are the prerequisite for reliable machine vision recognition.
