• Azalt® ECO2 binders are especially designed for the manufacturing of

warm mix asphalts

• As any binder of our Azalt® range, Azalt® ECO2 binders meet the

requirements of EN 12 591 (Bitumen and bituminous binders -

Specifications for paving grade bitumens)

• Warm mixes manufactured with Azalt® ECO2 binder show as good

mechanical performances as those of hot mixes and are consequently

recommended for the same laying applications :

– base course

– binder course

– surface course

WHY CHANGE FOR AN AZALT® ECO2 BINDER? CONTRACTORS & MIXING PLANT MANAGERS

• Azalt® ECO2 binders are « ready to use »

bituminous binders for warm mix asphalt

– No modification of asphalt plant process needed

• Zero investment

• No additional costs for maintenance

– No modification of mixes formula

• Compatible with a wide range of mixes formulas

and laying settings: base, binder and surface

layers, reclaimed asphalt pavement (RAP) content

up to 50 %, different kinds of aggregates

• No extra laboratory work needed on mixes recipes

– Handling similar to a conventional penetration grade

• No specific training needed for staff

• Azalt® ECO2 solution consists in a specific product formulation reducing handling temperatures up to 40 °C:

– on the road, at laying and compacting

• Quicker linking between laying of the successive courses

» Saving in time, improved productivity

• No fumes

» Relevant solution for works in confine environment (tunnels, car parks)

» Working conditions improvement for laying staff

• Lower perceived temperature

» Working conditions improvement for laying staff

– at the mixing plant, for manufacturing

• reduction of energy consumption of the mixing plant (up to 35 %)

» Improved productivity and competitiveness

• reduction of gaseous organic compounds (up to 47 %)

» mitigation of olfactory impact of the mixing plant

» contribution to conformity

Azalt® ECO² - Solutions for warm mix asphalts - ENG - 2014 10

• Azalt® ECO2 binders meet the requirements of EN 12 591

– Equivalent performances (compacity, water sensitivity, rutting) to

those of a hot mix with conventional penetration grade

• Sustainable and successful solution

• Azalt® ECO2 solution consists in a specific product

formulation reducing manufacturing and handling (laying,

compacting) temperatures up to 40 °C

– Quicker linking between installation of the successive layers

• Saving in time, improved productivity

– Earlier re-opening to traffic

• Reduced disruption to the travelling public

WHY CHANGE FOR AN AZALT® ECO2 BINDER? MANAGEMENT & INSTALLATION STAFF

• Azalt® ECO2 binders consist in a

specific product formulation reducing

up to 40 °C:

– installation temperatures (laying and

compacting)

• No fumes

• Lower perceived temperature

» Working conditions improvement for

laying staff

– manufacturing temperatures (at the mixing

plant)

• reduction of greenhouse gases (GHG)

emissions (up to 30 %)

» Contribution to the environmental

commitments of management

HANDLING RECOMMENDATIONS

Azalt® ECO² - Solutions for warm mix asphalts - ENG - 2014 12

HANDLING RECOMMENDATIONS

• For Azalt® ECO2 binders storage:

– Storage tank: empty entirely the tank before the

first discharge

– Storage temperature: equivalent to that of a

conventional equivalent penetration grade

– Storage duration: Azalt® ECO2 binders will remain

stable up to 15 days if bitumen storage best

practises are followed

• Handling of Azalt® ECO2 binders at the mixing

plant doesn’t require any equipments

modification

– Regular fonctioning of mixing plant equipments, at

a mixing temperature lowered up to 40 °C
