Hanson’s ERA 140 Gains BBA HAPAS Approval

Hanson’s ERA 140 Gains BBA HAPAS Approval
Written by Amy

Hanson has received an extension to the scope of its BBA HAPAS* Thin Surface Course certification to include its 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, explains: “ERA 140 incorporates a specialist bitumen or additives, which allows 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 was approached by Highways England to carry out an extensive warm-mix asphalt trial on a five-kilometre section of the M4 in the south west, which was witnessed by the BBA as part of the approval process.
