Road marking machine or road marking equipment is a kind of mechanical device that can paint traffic lines on the surface of highway. It is mean to keep the traffic order and safety. There are three types of road marking machines: thermoplastic paint, cold paint and two-component paint type. They are depending on the coating materials.
First, you need to choose thermoplastic paint. Roadsky supply high quality thermoplastic paint of different colors.
Second, pre-heater machine is needed. The powder of thermoplastic paintis heated in hot melt machine and the heating temperature should be controlled between 150℃ and 220℃. Third, When the coated primer is dry, you can add reflective glass beads, increased night time markings.
In highway and street construction, thermoplastic marking is widely used.
Thermoplastic road marking paint, is also known as hot melt marking paint. It is a kind of powder paint and need to be preheated before using. The heating temperature is between 150℃ and 220℃. And you need professional preheat machine to keep the temperature during long distance road lines marking work. After becoming liquid, the thermoplastic paint can be sprayed on the road surface. The coating then becomes a line after cooling.
The white paint and yellow paint are the most common color during the thermoplastic marking projects.
Two components marking paint consists of cold plastic paint and curing agent. When marking, the two components are mixed immediately before application to form the pavement marking. The service life of two component pavement marking normally ranges between 2 and 4 years based on traffic volumes.
Two-component pavement marking is used for marking project that need to be quickly applied such as car parks, road crossing and edge lines. The paint can be curing within 5-30 minutes depending on application method.
Two components marking have excellent performance on asphalt surfaces and are very resistant to snow plowing. Two component marking system is widely used in cold weather areas such as northern Europe.
Two component pavement marking paint is considered very expensive compared to other materials. In addition, special equipment is needed for applying two component pavement markings.
Two component road marking machine is equipped with two high pressure diaphragm pumps: one for cold plastic paint and another for curing agent. Changing the angle of two pumps will adjust the intersection point of paint and curing agent. While mixed, the curing agent will accelerate the forming speed of polymer methyl methacrylate pavement markings.
Two component marking system has many advantages compare to thermoplastic and cold solvent marking:
1. Quick applying. Rapid curing for less road blocking.
2. Exceptional adhesion to a variety of road substrates such as concrete and asphalt surfaces.
3. High retro-reflective. Glass beads and paint are tightly mixed.
4. Excellent weather resistance. Keep excellent performance in all temperature and weather.
5. Great wear and stain resistance. Long service life in poor conditions.
6. Environment friendly. Without solvent, the paint has little damage to environment.
Despite so many advantages, the cost of two component road marking is considered very expensive compared to other marking methods. Curing agent and special designed machines significantly increased the cost of road marking project. The structure of two component marking equipment is very complex, which leading to high maintenance cost. These all limit the application of this advanced marking method.

Pavement
marking materials mainly consist of thermoplastic paint, cold solvent paint and
marking tapes. Thermoplastic paint and cold solvent paint are the most common
materials for line marking projects. However, pavement tapes, a new marking
method, have been widely used in urban road construction.
Thermoplastic paint is the most common used
materials for line marking. It has advantages of long life on high volume road,
quick set time, good night time visibility and excellent durability. However, pavement
surface condition is an important factor that affects the performance. The road
surface must be clean enough. It requires specialized installation equipment, which
increase the initial cost of whole road marking project.
Cold solvent and waterborne paint cost less
than thermoplastic paint. Apply and clean-up of them is also very easy. But the
service life in high volume traffic road is much shorter. It also doesn’t
adhere well to concrete road.
Pavement
marking tapes can be divided into temporary tapes and permanent tapes. The main
materials of tapes are flexible polymer, synthetic rubber and thermoplastic
paint etc.
Removable road marking tapes can also be used in road construction sites as temporary markers. The
tapes can be placed to shift the lanes and black tapes can be used to
temporarily blackout the existing markings. At the end of the constructions or
within 6 months, the tapes can be pulled out off the surface without using
heat, solvents, or machines. Temporary marking tapes are ideal for short-term
applications such as work zones.
Permanent
tapes are designed to be long-term durable road markings capable of providing 5
to 8+ years of service life. The tapes are mainly used for marking edge lines,
centerlines, legends and symbols.
Thermoplastic
paint tapes, the latest launched permanent pavement tapes which are made from
thermoplastic paint. Put tapes in correct place and melt, the tapes will conform
and bond to the road surface.
Advantages
of permanent road marking tapes:
1.Easily
installed without special equipment.
2.Durable. Providing
5 to 8 years of service life depending on the traffic environment.
3.High retro-reflectivity.
4.Environment
friendly. Little damage to local environment and workers.
Pavement marking
tapes also have some disadvantages: high initial cost and not suitable for old roads
in poor conditions. The two factors limit the application of marking tapes. For more information about road marking industry, visit Roadsky News Center.
Roadsky recently released new thermoplastic paint pre-heater which can use both gas and diesel to heat the paint. Many
customers show their interests in this equipment. However, they are worried
about whether the operation is complex. So before the completion of formal
operation manual, Roadsky Technology Team records a video to help customers
understanding this new device. The new preheater use both gas and diesel
as the fuel. Customers can easily change the fuel by easily operating several
switches.

Road marking is a fast growing industry due to the infrastructure development of most countries. Development countries capture the largest share of the global road marking market. Increasing investments by foreign companies and rise in the standard of living are other major factors for the growth of the road marking market.
Road marking project mainly exists in in these construction projects: highway, airport, urban road and parking lots.
Highway construction: Markings on the highway are a major element in the traffic control system. Pavement markings serve a variety of functions, including: lane definition, separation of opposing flows, passing control, lane usage and designation, pedestrian crosswalks, stop lines, parking areas, word messages.
Urban road construction: Urban road marking mainly consists of street marking and residential area marking. The functions and operations are similar with highway marking. However, the scope of construction is limited in urban road construction project, sohand push road marking machineis the common used equipment.
Airport marking is projected to be the fastest-growing application of the road marking market, both in terms of value and volume. Airport markings include marking lines and rubber removal services on runways and taxiways in large and small airports (both commercial and privately owned). Thermoplastics, cold plastics, polyurethane, and epoxy-based paints are commonly used for airport marking application.
Parking lots: It is also used to mark spaces in parking lots or special purpose spaces for disabled parking, loading zones, or time-restricted parking areas. Colors for these applications vary by locality.
