    Electric paver debuts on A47: productivity and CO₂ lessons for road engineers

    First reported on The Construction Index

    30 Second Briefing

    An Ammann eABG 4820 electric paver has been deployed on National Highways’ A47 upgrade between Acle and Great Yarmouth, laying asphalt with over 90% recycled content alongside an electric Ammann eARX 26-2 tandem roller. The paver, claimed as the largest electric unit on the market, delivers up to 1,200 tonnes per day at 500 t/h with a 70% CO₂ reduction versus diesel, typically finishing night shifts at around 40% battery from a 95% start while placing 500–600 tonnes. Heidelberg Materials supported the trial by installing a nearby recycling plant that both supplied reclaimed material and provided daytime charging, with low-carbon hydrogen low loaders handling transport.

    Technical Brief

    • Variomatic screed on the eABG 4820 allows variable paving widths up to 6.5 m.
    • Nightly production on the A47 reached 500–600 t, far above typical 100–200 t highway shifts.
    • Heidelberg Materials’ temporary recycling plant was sited close to the works to minimise haul distances and emissions.
    • The same recycling plant served as the daytime charging hub for the electric paver fleet.
    • Low‑carbon hydrogen‑fuelled low loaders were used for plant transport, cutting diesel haulage demand.
    • Ammann eARX 26‑2 light tandem vibratory roller reportedly completed four consecutive night shifts on one charge.
    • Operators reported very low drivetrain noise on the eABG 4820, improving verbal communication and site safety.

    Our Take

    National Highways’ use of an electric Ammann paver on the A47 aligns with its emerging sustainability framework for schemes like the £11bn Lower Thames Crossing, signalling that low‑carbon plant and high recycled content surfacing could become baseline expectations on future Strategic Road Network renewals.

    The A47 trial’s combination of over 90% recycled surfacing materials and a claimed 70% CO₂ saving from the paver provides a live test case for National Highways’ new £968M legacy concrete roads reconstruction framework, where contractors such as Kier, Graham and Sisk will be under pressure to demonstrate similar carbon and circular‑economy performance.

    Ammann’s presence here, alongside its dealer network expansion in the UK reported in our database, suggests it is positioning to capture demand as UK clients like National Highways increasingly specify electric and low‑emission plant for high‑output sites handling 500–600 t per night or more.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
