TEMPERA®
THE WARM MIX PRODUCT RANGE FOR
SUSTAINABLE ROADS
As part of its strong commitment to designing a more sustainable road infrastructure, Eurovia, in conjunction with MeadWestvaco have developed Tempera®, a warm mix asphalt range that performs identically to their conventional hot asphalt counterparts.

 

KEY BENEFITS

- Improved durability

- Limited environmental impact

- Reduced work site disruption

- Excellent workability

 

KEY FIGURES

- Material temperature reduced by up to 50°C 

- Greenhouse gas emissions reduced by 20 to 40%

- Over 1,000,0000 tonnes produced to date worldwide

 

SOUGHT AFTER
QUALITIES

Tempera® is the result of a combination of technologies, applied to both products and processes which significantly reduce the production and installation temperatures of the asphalt materials.
The Evotherm additives ensure excellent binder/aggregate adhesion, along with good workability and compaction characteristics, equal to those of their conventional hot asphalt equivalents.
Additionally, typical hot asphalt materials will age harden by as much as 40% during the production cycle. This is caused by the light oil bitumen fraction being boiled off and ultimately affecting the binder’s age. By using Tempera®, the subsequent temperature reduction significantly reduces the age-hardening process; therefore, the material’s durability and long term performance are improved.

 

BETTER
ENVIRONMENTAL PROTECTION
Lowering the production temperature generates substantial environmental gains. The use of Tempera® makes it possible to lower:

- Greenhouse gas (CO2, NOx, SOx etc) emissions
- Emissions of odours during    installation

Moreover, the Evotherm additives are derived from renewable non-food plant materials.
