Hanson’s ERA 140 gains BBA HAPAS approval

Hanson ERA warm-mix asphalt

Company now able to offer Clause 942-accredited thin-surface course products in a warm-mix option

HANSON have received an extension to the scope of their British Board of Agrément (BBA) Highway Authority Product Approval Scheme (HAPAS) thin-surface course certification to include their ERA 140 warm-mix asphalt.

The news means the company can now offer customers Clause 942-accredited thin-surface course products in a warm-mix option, which offer environmental, performance and safety benefits.

Adrian Hadley, head of technical (asphalt and aggregate) at Hanson, explained: ‘ERA 140 incorporates a specialist bitumen or additives, allowing the asphalt to be produced at reduced temperatures. This leads to a fall in CO2 emissions and can result in enhanced durability and faster completion of resurfacing work.

‘The extension to our scope is the result of an intensive period of in-house testing, which has subsequently been monitored and approved by the BBA. It demonstrates that producing our thin-surface brands, such as Tuffgrip and Durafalt, using ERA140 technology has no impact on their performance or workability.’

Hanson were approached by Highways England to carry out an extensive warm-mix asphalt trial on a 5km section of the M4 in the South West, which was witnessed by the BBA as part of the approval process.

Am curious to hear if the specialist bitumen or additive has a negative impact on recycling the asphalt again after its life, which is the case with PMB or waxes
