A MULTI-PURPOSE PRODUCT Fibrovia® is suitable for all types of traffic; it can be used for maintenance and new construction projects. The main purpose of Fibrovia® is to improve the surface characteristics of pavements that exhibit no structural weakness. Fibrovia® is an ideal surfacing solution for urban roads where its workability allows uniform installation, both mechanically and by hand. An integral part of the Fibrovia® Thin Surfacing System is the use of a bond coat. The application rate is adapted to the type of substrate. Excellent bond and waterproofing characteristics ensure a concise service life for the surface and the underlying pavement.
A BINDER-RICH FORMULATION Developed in France during the 1980’s the formulation of Fibrovia® combines a dense graded, but very coarse mineral skeleton with a high binder content. The use of short fibres with a high specific surface area makes it possible to increase the mastic content, when compared to conventional formulas. Fibrovia® is 100% recyclable, thus reducing the amount of material being sent to landfill.
Texture Retention
Fibrovia® retains its texture on the most densely trafficked sites: greater than 5,000 commercial vehicles/lane/ day for stress levels 1 and 2, and greater than 2,500 vehicles/day/lanes for stress levels 3 and 4.
Skid Resistance
Excellent levels of skid resistance can be expected due to the quality, high PSV aggregates used in Fibrovia®. Excellent SCRIM levels can be maintained.
Deformation Resistance
Fibrovia® meets BBA HAPAS Level 3, the most stringent requirement for deformation resistance. This permits its use on the densely trafficked roads without fear of rutting.

HIGH QUALITY PAVEMENTS
FOAM BITUMEN TECHNOLOGY
TARGETED EFFECTIVENESS
The basic principle of Recofoam® is to expand bitumen via contact with small amounts of water under carefully controlled conditions; then mix the foamed bitumen with cold moist aggregate.
The process is based on surface tension: when the bitumen foam collapses the binder grips the fine particles, which in turn forms a strong mortar that encapsulates the coarser particles.
Foamed bitumen provides a uniquely strong adhesive binder system that enables the use of a wider range of new and recycled aggregates. Recofoam® is often as strong, after curing as conventional asphalt alternatives whilst being more rapid curing than emulsion bound materials.
In the case of Recofoam® HD, a hydraulic binder is also included to ensure improved cohesion and immediate strength during the curing process.
Recofoam® is also proven to stablise and encapsulate asphalt waste containing tar preventing any contamination leaching into the surrounding environment.
PROTECTING THE ENVIRONMENT
The Recofoam® range helps protect the environment, not only by using recycled materials but also through its cold production process.

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.

VERSATILITY COMBINED WITH PERFORMANCE
A MULTI-PURPOSE PROCESS
UL-M® is suitable for all types of traffic and can be used for maintenance and new construction proJects. It can also be used to overlay existing surfacing. The main purpose of UL-M is to improve the surface characteristics of pavements that exhibit no structural weakness.
UL-M® is typically applied using conventional paving equipment;
at ultra-thin layers specialist equipment, which includes pavers with an integrated spray bar for applying the bond coat are utilised.
An integral part of the UL-M® thin surfacing system is the use of a bond coat. The application rate is adapted to the type of substrate excellent bond and waterproofing characteristics ensure a concise service life for the surface and the underlying pavement.
ONGOING VERSATILITY
Developed in France during
the 1980’s UL-M® uses high performance polymer-modified bitumens which have high cohesion, low thermal sensitivity and excellent resistance to aging. Different degrees of modification make it possible to adapt the choice of binder to the performance requirements, nature and characteristics of the substrate, traffic loadings and weather conditions.
UL-M’s gap-graded formulation, along with the binder give the products excellent resistance
to deformation and surface characteristics.
UL-M® is 100% recyclable, thus reducing the amount of material being sent to landfill.

ULTRAPHONE ®
LOW NOISE THIN SURFACE COURSE
As the traffic volumes within urban areas increase, this poses strong political pressures to reduce traffic noise, thus improving the urban population’s standard of living.
Ultraphone is a low noise surface course material, developed by Jean Lefebvre (UK) which meets every expectation of those living in the vicinity. It combines the benefits of exceptional noise reducing properties with excellent skid resistance characteristics.
KEY BENEFITS
- Substantial reduction in rolling noise
- Excellent skid resistance
- Reduced spray in wet weather conditions
KEY FIGURES
- Perceived traffic reduction of ≥ 50%
- Installed at depths of between 20 and 30mm
THE WINNING FORMULA
Ultraphone efficiently and sustainably combats tyre noise (rolling noise) pollution generated by moving traffic. Its design lowers the risk of long-term silting up, unlike porous asphalt; therefore, its acoustic performance is maintained. Based on these intrinsic properties it is surfacing best suited for the construction and maintenance of urban and suburban pavements.
In addition to comfort and safety, Ultraphone offers a homogenous surface which is aesthetically pleasing.
Ultraphone is typically applied using conventional paving equipment. An integral part of the system is the use of a bond coat. The application rate of this is adapted to suit the type of substrate; thus ensuring an excellent bond and waterproofing characteristics prolong the service life of both the surface and the underlying pavement.
EXCELLENCE ACROSS THE BOARD
Developed in France during the 1980’s Ultraphone uses high performance polymer-modified bitumen, which have high cohesion, low thermal sensitivity and excellent resistance to aging. Different degrees of modification make it possible to adapt the choice of binder to the performance requirements, nature and characteristics of the substrate, traffic loading and climatic conditions.
Ultraphone’s 0/6mm gap-graded formulation, along with the binder properties give the material excellent resistance to deformation, along
with acoustic and skid resistance characteristics.
Ultraphone is 100% recyclable, thus reducing the amount of material being sent to landfill.
The special formulation provides Ultraphone with its low rolling noise and excellent skid resistance properties.
Optimised Noise Reduction
The standard analysis of measuring road noise is the Statistical Pass-By method. The principle is to measure the emitted noise a person at the side of the road would hear as various vehicle types pass by, taking account of the amount of noise absorbed by the road surface. For a particular surface, the volume of noise will depend on vehicle speeds and the combination of vehicles in the flow.
Noise is measured in units called decibels (dB). The human ear is not equally sensitive to all frequencies, so a measure known as ‘A’ weighting is used to give dB(A). It is a log scale, so a decrease of 3dB(A) is equivalent to the halving the traffic, or doubling the distance away from the source.
Surveys have shown that even with traffic speeds of 30mph, the reduction on noise with Ultraphone compared to an adjacent section constructed with standard 0/14 Thin Surfacing was 5.7 dB(A).
This is a very significant and noticeable improvement, equivalent to reducing the traffic by 75%.
Greater Safety
Ultraphone is capable of providing adequate friction at both low and high speeds even though its in-service surface texture may be relatively low when measured by conventional techniques.
This is due to the 0/6mm gradation, which provides a higher proportion of aggregate in the road/ tyre interface, thus improving the grip.
SCRIM analysis has indicated that Ultraphone consistently outperforms other thin surface course materials produced with larger size aggregates from the same source.
