EP-GRIP also for safe city roads: Many accidents used to occur every year in this curve. The accident concen-tration in the city center of Francfort was successfully defused with EP-GRIP.

More gripfor permanent traffic safety

EP-GRIP coatings offer many safety

relevant benefits:

g shortened braking distancesg increased cornering forceg reduced hazard of aquaplaningg less surface spraysg better visibility in the dark

(when selecting brighter stone types)g no hazard due to retroactive binding

agent accumulation on the surface

The EP-GRIP Coatings are surface treat-

ments on the basis of binding agents made

of reaction resin in accordance with ZTV

BEB-StB as well as TL BEB-StB, TP BEB-StB or

the BEB leaflet.

The „Leaflet for grip improving actions at

traffic surfaces made from asphalt“ also

recommends the reaction resin coating as a

qualified construction measure.

Due to its stone granulations with high

resistance to polishing, the installed

coating offers grip values between 70 and

85 SRT units.

Measurements with the side force

measurement process (SKM) on the German

freeways resulted in adhesion coefficients

of μ ≥ 0.7 at 80 km/h measurement speed

and at 40 km/h in the area of acceleration

and deceleration lanes, loops and tangents.

Insufficient grip is often the cause for

the fact that a road section develops

into an accident concentration

especially if the road is wet.

However, the road construction on

many segments of this road are

otherwise completely intact. In such

cases, a grip in accordance with the

technical set of rules ZTV BEB-StB or ZTV

Asphalt-StB can be reestablished quickly

and without complications by using

EP-GRIP coatings.

Maintenance free for years – no costs for years

The maintenance-free coating protects

the roads permanently against traffic

stresses, weather and environmental

impacts - and that for many years.

During this time, the EP-GRIP maintains

its performance characteristics.

A glance at the costs shows that this

is also in the long run the most

economical method for the permanent

guarantee of the traffic safety.

Maintenance, service or other

subsequent costs are not generated.

The EP-GRIP coating consists of a

binding agent on the basis of reaction

resins into which a mixture of fine and

coarse stone granularity resistant to

polishing is spread.

This surface treatment has a dual effect

– through its fine and its coarse

roughness. Especially selected stone

granularities with a very high micro-

roughness increase the friction between

tire and road and therefore provide the

required grip. The micro-roughness is a

result of the grain size of the stone

granularity.

It is responsible for the outstanding

drainage effect of the EP-GRIP coating

and provides high grip to the coatings,

even if it is raining or wet.

Less noise,more brightness

EP-GRIP coatings are environmentally

friendly and sustainable in many aspects:

g This process already saves energy

during the installation because the

resin will be applied in a cold condition.

CO2 emissions for the heating of

machines or mixing materials are not

required at all.

g The long usage duration prevents

energy expenditures for later

maintenance and service actions and

therefore contributes to the sustainability

of the process.

g The fast installation reduces traffic

obstructions and unnecessary exhaust

gas emissions through traffic jams to

a minimum.

EP-GRIP coatings also reduce the costs:

g The coated surfaces require less

de-icing salt in winter because a

significant contact between the tires

and the fine rough-structured surface

is provided for a longer time.

g The costs for the construction of a

noise protection wall would be – for a

comparable noise reduction – at least

5  - 10 times as high as the application

of an EP-GRIP coating.

Loud roads become quieter ...

EP-GRIP coatings provide a valuable

contribution for the active noise

protection. The optimal texture and

roughness depth result in a significant

reduction of the tire-road noise, which is

developed when tires unroll on the

road. Measurements with the CPX

method (noise measurement trailer)

provide proof for a reduction of the

sound pressure level of up to 75%.

Tests have repeatedly provided proof for the resistance of the EP-GRIP coating against heat, fuels and de-icing salt as well as frost exposure.

Dark tunnels become brighter ...

EP-GRIP coatings glare significantly less

in case of wet roads than conventional

coatings, because the light mirroring or

reflection in the water film is reduced by

the grain peaks, which break through

the water film.

The reduction of the noise level at a

measuring speed of 100 km/h is up to 6

dB(A). This is equivalent to a perceived

reduction of the noise emission by also

75%. In this connection, proof for a

DStro- value of -5 dB(A) was provided for

EP-GRIP.

This economic process is especially

often used on bridges and valley or

trough locations because other noise

protection measures are often not

possible for constructional reasons.

An additional brightening effect is often

achieved when using bright stone

granularities. It causes a significant

increase of the brightness in tunnels

and trough locations in connection with

significant energy savings for the

lightning.

Depending on the requirements and the application, different stones are used. The spectrum includes very bright spread materials such as bauxite (left), bright granite (center) for the brightening of tunnels and dark stone granularities (right).

EXPERTS FOR SURFACES

EP-GRIP Coatings achieve their grip

through high quality spread materials

with exactly defined granularity and

high resistance to polishing with at least

category PSVlisted (58) and outstanding

shock destruction values (Category SZ18

resp. LA20).

The high grip is maintained for a long

time because only stone granularities

are used that are resistant to polishing

and that „re-sharpen themselves“.

The spread material can be used with

different granularities.

In accordance with ZTV BEB-StB as well

as TL BEB-StB, TP BEB-StB or leaflet BEB,

the granulations are 1/2 mm, 1/3  mm,

2/3 mm or 3/4 mm. However, other

granularities can be provided on

request.

The selection of the required stone

granularity depends on the required

texture and the future tasks of the

surfaces to be treated.

We would be pleased to provide

consultation to decide which

granulations best fulfill the specific

application requirements.

EP-GRIP for concrete

The installation on concrete roads is

provided without interruptions in the

area of the gaps. In addition, the

EP-GRIP coating acts as a sealing of

worn, older concrete surfaces. EP-GRIP

can contribute to a significant extension

of the usage duration of concrete

surfaces.

For many years, airport operating

companies prefer POSSEHL ANTISKID®

coating, a variant of EP-GRIP on air

traffic surfaces. The reaction resin

provides three major application

advantages on de-icing surfaces:

Due to the drain effect, the de-icing

agent will be removed quickly from the

surface. The outstanding grip provides a

high safety level and the sealing effect

protects the concrete permanently.

The binding agent will be applied through combs to the prepared road or air-traffic surface.

EP-GRIP for asphalt

A special binding agent, which has a

flexibility adapted to the asphalt, was

developed for the use on asphalt. This

binding agent layer can compensate

temperature variations and the resulting

elongations of the underlying road

without being damaged and without

losing stability. Therefore, this coating

system demonstrably withstands the

stresses of the traffic for many years.EP-GRIP will be applied in parallel to the moving traffic. The binding agent binds the scattered stone granularities immediately. The grains do not swirl even if a truck passes the construction site.

A strong team

EP-GRIP Coatings are used successfully in

practical applications since 1986. In the

meantime, a few million square meters of

traffic surfaces have been coated using this

process.

Daily productions of up to 15,000 m² are

possible. An experienced team does not

only ensure the flawless function of the

devices and the correct composition of the

coating system but also the thorough and

expert execution of the work.

A proven system

The coating with EP-GRIP can be perfor-

med during the day and at night. Prerequi-

site: The surfaces to be coated must be

qualified, clean and dry.

Ramp ups for the height equalizations

between the EP-GRIP coating and the

adjacent road surfaces are not required. In

addition, existing permanent markings can

be maintained.

EXPERTS IN SURFACINGS

The EP-GRIP coating is produced as a

mobile day and night construction site,

normally with a single lane closing.

The flexible reaction resin binding agent

will be applied onto the clean

substructure with a mobile two

component mixing and application

machine and will be spread with stone

granularities.

The stone granularities will initially be

spread in excess and afterwards

compacted. The excess spread material

will be swept off and vacuumed in one

work step after only 3 to 4 hours after

the application of the reaction resin.

Afterwards, the road can again be used

for traffic.

A computer controlled mixer for the

binding agent assumes the metering of

the resin and hardener components.

The binding agent will be evenly

distributed on the road through a pour

bar. The driving speed of the application

device depends on the work width and

the required volume of binding agent.

The continuous control of the binding

agent flow guarantees the required

layer thickness.

In addition, the design type of the pour

bar provides a drip-free, even and spray

vapor free application. Additional

application benefit of the POSSEHL

technology: The unique Vario module

permits a change of the width during

the application.

Reestablishment of the traffic safety at the Francfort highway intersection: The coating with EP-GRIP on this high accident concentration section provided the required grip to the asphalt after only one afternoon.

Since then, the number of accidents due to lacking grip has been completely reduced.

Immediately after the application of the reaction resin, a line spreader distributes the spread material evenly on the entire work width. Traffic impairments due to sprayed spreading material will be prevented by imme-diate sweeping of the excess stone granularity after the hardening.
