Road safety has always been an important issue in urban transportation planning, and vibrating road marking, as an effective traffic safety facility, is gradually becoming an important part of the road marking field. Thermoplastic Paints, as one of the most commonly used materials for such markings, play an important role in enhancing road safety with their unique properties and wide applicability. The process of creating these vibrating road markings is a multi-step, finely controlled process in which temperature, thickness and pattern design all need to be precisely controlled. Below is a detailed breakdown of the construction process, covering the road marking machines used, construction techniques and key considerations:
Construction process of vibratory road marking
1. Pavement Preparation
Prior to the application of any markings, the road surface must undergo a thorough cleaning process to ensure that the thermoplastic paint adheres firmly. Dirt, debris, grease, and other contaminants can prevent the paint from bonding properly. To do this, we utilize the following tools:
Blowers: utilize high-pressure airflow to blow debris off the pavement.
High-pressure washers: Remove stubborn dirt and grime.
Sweepers: Large mechanical sweepers are used to remove larger ground debris.
In addition, the pavement must be kept dry, as wet conditions can seriously affect the adhesion of the coating.
2. Heating of Thermoplastic Paints
Coatings used for road markings are usually thermoplastic, which means that they can be melted and applied in a liquid or semi-liquid state, and then cured and hardened when cooled. These coatings consist of resins, pigments, reflective glass beads, and fillers that maintain high durability and excellent visibility even in low light conditions.
Coatings are heated to approximately 180-200°C (356-392°F) in a melting pot or tank machine to obtain a consistency suitable for application. This process needs to be continuously monitored to ensure that the temperature remains within the desired range. Excessive temperatures will reduce the quality of the coating, while temperatures that are too low will affect the application.
Heating equipment includes:
Furnaces or melting machines: large industrial equipment used to melt and maintain a constant temperature for the coating.
Preheating stations: In some cases, used to prepare small quantities of paint for use as the machine moves along the road.
3. Application of Thermoplastic Paints
Vibratory marking paint applications require a high degree of precision and are designed to create a wavy texture pattern that produces a vibratory effect when a vehicle drives over it.
The main application machines are road marking paint machines, which are equipped with various tools and mechanisms to apply molten thermoplastic paints in a controlled manner.
Vibra Line Road Marking Machine: Specialized vehicles, equipped with hoppers, spray guns or extruders, are used to apply the paint uniformly to the road surface. The machine maintains the coating at the proper temperature by heat and has a mechanism to regulate the flow of the coating.
Extruder System: Usually used in conjunction with a roller system to spread the molten coating onto the pavement in the desired shape.
Key considerations during application include:
Pattern Creation: Waves or ridges are created by adjusting machine speed, movement and paint thickness.
Multi-layer application: Thermoplastic Paints can be applied in layers to create a 3D effect and enhance vibration.
Application speed: The speed at which the marker machine moves directly affects the uniformity of the pattern and needs to be tightly controlled.
4. Creating an oscillating effect
The key to vibratory road marking is the precise control of texture and pattern.
Wave pattern design: Carefully planned patterns consisting of evenly spaced alternating high and low ridges create a bouncing or vibrating effect on vehicle tires.
Frequency and amplitude: The crests and heights of the ridges need to be carefully controlled, with typical wave intervals of 30 to 50 centimeters and amplitudes of 3 to 5 millimeters.
Grooves or ridges: Some machines are equipped with grooving tools or pattern boards to create physical undulations directly on the pavement.
Reflective material: Glass beads are added to increase visibility and ensure that the markings are clearly visible both day and night.
5. Cooling and hardening
Once applied, the thermoplastic paint cools and solidifies quickly, creating a durable, non-slip surface. The cooling process usually takes only a few minutes, and the road can be reopened to traffic shortly after the markings are placed. However, to ensure the durability and effectiveness of the markings, it is recommended that road markings be allowed to cure for approximately 20-30 minutes before allowing high speed traffic.
6. Quality control and inspection
A number of checks are required after marker application to ensure the effectiveness of the vibratory road markers:
Thickness and Pattern Check: Ensure that the markings are of uniform thickness and have a consistent waveform pattern.
Reflectivity test: Test the reflectivity of the markings using specialized instruments to meet visibility standards.
Durability check: to assess the markers’ resistance to abrasion, especially in heavy traffic and adverse weather conditions.
Key advantages of Thermoplastic Paints for vibration marking
Durable: Thermoplastic Paints are extremely durable and can withstand heavy traffic, inclement weather and abrasion.
Fast drying: the coating hardens quickly and the road can be reopened almost immediately after application.
Visibility: When combined with glass beads, the reflective properties of the coating ensure that markings are visible day and night.
Cost-effective: Thermoplastic Paints offer the perfect balance between cost-effectiveness and long-term performance.
The production of vibrating road markings using thermoplastic coatings is a highly controlled process involving surface preparation, melting and precise application of the coating and the creation of specific wave patterns. The process relies on specialized machinery such as vibra line road marking machines with extruders or pattern heads to ensure that the markings are effective, durable and clearly visible. Proper execution of this process is critical to improving road safety, alerting drivers and preventing accidents caused by fatigue or inattention.
