evoBuild Foamed asphalt
evoBuild circular foamed asphalt is a cold mix asphalt containing up to 95% recycled materials, reclaimed fillers/additives, bitumen, cement, and water. It can reduce the carbon emissions associated with asphalt production and laying by a minimum of 40% compared with conventional hot mix materials.
The product is manufactured by injecting water and air into hot bitumen under high pressure, which causes the bitumen to foam, increasing its volume and decreasing its viscosity. This allows the effective coating of aggregate.
Recycled materials that can be used include:
- Recycled asphalt planings (RAP)
- Tar-bound planings
- Excavated asphalt
- Crushed concrete
- Reclaimed granular sub-base
evoBuild circular foamed asphalt 40 R95 is designed and manufactured in accordance with ISO 9001 and is compliant with:
- Specification for Highways Works Clause 948
- TRL Report 611
- CD226 Design for New Pavement Construction
- BS 9228 For Recycling of Roads
Applications where evoBuild foamed asphalt can be used:
- Highways - major and local
- Industrial/commercial infrastructures
- Housing developments
- Lorry and car parks
- Airports – civil/MOD
- Ports infrastructure
- Rail infrastructure
- Footways/cycleways
- Haunching/trenches
Benefits of evoBuild foamed asphalt
- Carbon savings
-
evoBuild foamed asphalt requires less energy to manufacture than conventional asphalt, cutting carbon emissions by a minimum of 40%. Manufactured and installed to PAS2080 standards/certification.
- Reduced hazard exposure
-
Low production temperatures greatly reduce fumes, odours and steam emissions. This minimises the risk of burns from materials and offers a generally safer and more comfortable working environment for operatives and road-users.
- Workability
-
evoBuild foamed asphalt can be immediately placed and compacted on site, or it can be stockpiled for later use, extending working times and ensuring continued supply.
- Productivity
-
Material curing times are reduced enabling earlier trafficking, increased outputs and reduced programme durations leading to less disruption for road users.
- Waste hierarchy application
-
Realising value from existing pavement materials, evoBuild foamed asphalt promotes the circular economy, reducing waste and minimising environmental footprint.
- Reusing hazardous waste
-
evoBuild foamed asphalt encapsulates tar-bound planings, allowing for their safe re-use in carriageway construction. This avoids substantial fees associated with transporting and disposing of hazardous waste at regulated landfill sites.
