Our Asphalt Preservation Services

Henry Williams & Son has a long track record of quality asphalt preservation projects – from (small project) to (large project).

Our asphalt preservation services are sustainable, cost effective and with low carbon, allowing highways managers, private businesses and airport planners, for example, to pre-empt degradation. Our services extend the life cycle of carriageways, pathways, and runways many times over, and we save local governments, highways agencies and commercial organisations unnecessary spending.

Working quickly and efficiently using our skilled highway engineers and project planning teams, together with our preferred RHiNOPHALT treatment, we:-

  • Minimise disruption
  • Maximise speed
  • Work with you to schedule your project at the most convenient time.

What is Asphalt Preservation?

Growing in demand, asphalt preservation is a sustainable and cost-effective process, where the surface life of a road or footway can be significantly extended.

We work quickly and efficiently, using our preferred Rhinophalt® treatment and our skilled highway engineers and project planning teams to minimise disruption, maximise speed and schedule your work at the most convenient time.

Here at Henry Williams & Son (Roads) Ltd, we use our specialist bespoke plant to apply ASI Solutions’ RHiNOPHALT Asphalt Preservation Treatment which:-

  • Preserves, protects and significantly extends the life of the asphalt infrastructure
  • Minimises disruption to the public by applying during night closures
  • Reduces carbon by 90% compared to traditional resurfacing
  • Meets the requirements of Clause 950 in the Specification for Highways Works with BBA HAPAS certification and CE Mark.

What are the benefits?

The two primary advantages to asphalt preservation are:-

  • Sustainability and
  • Cost-effectiveness

  • and include:-

  • Asphalt preservation treatments can be applied more than once where heavy usage puts additional pressure on asphalt surfacing
  • High-speed applications – includes damage prevention which enhances the condition, appearance and performance of surfacing systems
  • Avoidance of the need for replacement of otherwise suitable highway surfaces from wear and tear
  • Improvement of quality where surfacing is subject to quality standards or testing (ie. aviation industry)
  • Reduction of costs with reactive maintenance designed to manage deterioration, potholes, cracks, and gaps - which would cost considerably more than a preservation treatment
  • The minimisation of the risk of accidents and insurance claims
  • Long-term protection using RHiNOPHALT and our skilled surfacing engineers.

What is RHiNOPHALT?

RHiNOPHALT extends the life of surfaces or asphalt infrastructure as a viable alternative to replacement due to wear and tear.

By preserving and protecting the asphalt surface, RHiNOPHALT is one of the most sustainable asphalt maintenance systems available. It extends the life of the surface course by up to 100%; reduces the number of times it needs to be resurfaced and reduces reactive maintenance.

Sustainability through preservation conserves the valuable mineral resources and fossil fuel binders.

Key benefits of RHiNOPHALT include:-

  • Slowing the oxidisation and deterioration of carriageways and footpaths
  • Over 90% reduction in carbon footprint
  • Significant reduction to disruption to road users as up to 40,000sqm per shift with night time application and road markings reinstated in the same shift
  • Reduction of the demand for reactive maintenance and associated costs.
  • Extension to the life of any asphalt surface in a reasonable condition by up to 15 years (ie. can be treated and then retreated again after 5 and 10 years).
