EUCOPAVE
PAVEMENT TYPE
AsphaltFlexible pavement
ConcreteStiff pavements
EucoPave® (semi-flexibleconcrete asphalt)
ADVANTAGES
Flexible, jointless, sounddampening, fast applicationand ready to use
Durable, high load bearingcapacity, high wear, impact andsolvent resistance and lightcolour
Semi-flexible, jointless, load bearing capacity, high wear, impact & solvent resistance, light color,fast application and curing time
DISADVANTAGES
Limited strength,/limitedstatic load bearing capacity,dark color
Long curing time, joints,cracks and great thickness
Two applications cycles, limited load bearing capacity comparedto concrete

EUCOPAVE - MATERIAL COMPOSITION● Ultra-Fine Cement:
➤ Binding material, main contributor to compressive strength
● Microsilica:
➤ Densifier, contributes to compressive strength and “lubricates” the particles
● Superplasticiser:➤ Lubricates and packs the particles
● Aggregates

EUCOPAVEINSTALLATION OF EucoPave® MORTAR
Quick return to service. Short shut-down time
The following table provides guideline as to how many hours a EucoPave® pavement should typically cure at various temperatures before being subjected to the given loads. The guidelines should be considered as average values as many conditions influence the curing process.
Degrees in Fahrenheit Type of Use 77 68 60 50 40 Light Pedestrian traffic 10 12 16 24 41 Mechanical loads Truck, lorries, traffic etc. 19 24 32 48 81 High pressure cleaning 38 48 64 96 162 If temperature drops to freezing the curing process will stop, but will start again once the temperature rises above 32 degrees Fahrenheit.
