The ultimate resurfacing solution

When busy roads need to be resurfaced, time is critical. Dual layer reconstruction can mean prolonged road closures, while unexpected sub surface conditions can lead to further delays and mounting costs.

In recognition of this, Tarmac has developed ULTIPHALT SINGLE LAYER, a versatile 20mm SMA based asphalt, designed to replace surface and regulating or binder courses in a single pass. This can reduce overall project costs, as well as project delivery times and also minimise disruption for road users. It has excellent load bearing capability and maintains its surface texture even on heavily trafficked routes. This makes it suitable for resurfacing all types of roads, from motorways and trunk roads to rural roads and residential streets.

ULTIPHALT SINGLE LAYER is available for installation by accredited contractors who have full access to our expert training, advice and technical support.



  1. Faster completion

    Single pass construction significantly reduces construction times, minimising costs and disruption for clients and end users.
  2. Ultimate versatility

    BBA approved for use between 50-75mm, however, frequently used at depths up to 100mm, to resurface a wide range of roads from motorways and trunk roads to rural roads and residential streets.
  3. Excellent durability

    Using a 20mm nominal size high PSV aggregate, ULTIPHALT SINGLE LAYER offers comparable surface texture and deformation resistance to a 14mm SMA surface course, along with lower voids and higher stiffness.
  4. Improved Sustainability

    Improves sustainability and helps conserve scarce resources by spreading demand from the commonly used 14mm and 10mm SMAs and reducing waste from processing.
  5. Improved finish

    Better heat retention within a thicker single course improves joints and allows better compaction.
  6. Ultimate Support

    At Tarmac, technical excellence comes as standard. ULTIPHALT SINGLE LAYER is available for installation by accredited contractors who have full access to our expert training, advice and technical support.

  7. Proven performance

    BBA / HAPAS approved since 2005, ULTIPHALT SINGLE LAYER has been proven to deliver lasting performance on heavily trafficked routes.
