Providing fresh hot asphalt at its point of use

What is your proposal?

Ultipatch Sitemix is an asphalt range that is used in conjunction with low volume asphalt mixer technology, providing fresh hot asphalt at its point of use. This enables high levels of workability and compaction to be achieved, providing a more durable defect repair at any time of day or night.

What does it do?

The solution eliminates the common challenges faced by contractors in maintaining the temperature and workability of product, eradicating material wastage and accessing product in the quantities required whenever they are needed. Ultipatch Sitemix means that a quality permanent hot repair can be done first time.      

How does it meet the challenge?

Maximising productivity when dealing with minor defects on the road network is a continuing challenge. Ultipatch Sitemix enables the contractor to service these repairs without being restricted by the operating hours of asphalt plants. By effectively becoming 'mixing self-sufficient' and totally in control of their operations, a contractor is much more productive when the non-productive man hours spent travelling and queuing to collect asphalt are available on site carrying out repairs instead. This solution results in zero material wastage, enhanced durability, fewer follow up repairs, less disruption to road users and lower fuel usage from travel and the heating process.

02 Material Edge   

Third generation porous asphalt for noise reduction

What is your proposal?

Development and use of a third-generation porous asphalt in the Netherlands is a golden opportunity for the UK Highways industry.

What does it do?

Some 1.2 million square metres of the material was laid in the Netherlands between 2013 to 2016 on the A15 Maasvlakte to Vaanplein (MaVa) project near Rotterdam. This resulted in wide ranging benefits including increased road capacity due to reduction in splash and spray; fewer accidents resulting from aquaplaning; markedly reduced noise compared to conventional surfacing; 50% longer life than traditional porous asphalt; 30% less CO2 emissions than traditional porous asphalt; and improved vehicle fuel efficiency due to reduction in rolling resistance in all weathers.

How does it meet the challenge?

Already tried and tested in Holland, third generation porous asphalt has a 22-year structural guarantee, offers high noise reduction and a 12-year minimum life for the asphalt surfacing with only one resurfacing renewal. The Dutch have solved many of highways major problems. The UK Highways industry and the public should and can benefit from their experience.

Bagged site mix hot asphalt, where and when required

             

What is your proposal?

Armaphalt is a bagged, site mix hot asphalt developed for re-instatement teams. Material is added directly into a mobile low volume batcher, allowing small quantities of asphalt to be produced on site where and when required. 

What does it do?

Armaphalt allows crews to go straight to site with no queuing at the asphalt plant, improving daily productivity. Patching with hot material all day increases the longevity of repairs, reducing the potential for failures. Further benefits include a reduction in waste materials and faster reactive maintenance.

How does it meet the challenge?

Current methods of reinstatement works are outdated, often subject to delays caused by material supply and in some instances result in large amounts of unused and costly wasted material. Armaphalt not only creates a long lasting permanent repair, but also helps to considerably reduce the negative aspects of conventional repair methods. Only taking to site the quantity of material you require, means you only use what you need to use. Using bagged asphalt also reduces the company's carbon footprint as a consequence of fewer vehicle movements and less waste.

04 LKAB Minerals

Pothole hot repair process using magnetite

What is your proposal?

LKAB Minerals and partners are seeking to develop a pothole hot repair process, with the objective to provide a repair lasting up to 75% of the total road life. 

What does it do?

The process involves the heating of the repair area using a patented gas-powered pothole heater, before applying heated magnetite asphalt to the area. The use of magnetite and its thermal conductivity properties, creates a stronger bond to the existing area and minimises the risk of cracking. 

How does it meet the challenge?

A long-lasting pothole repair solution would ease the burden on local councils and maintenance budgets. This repair system aims to provide a longer lasting repair, whilst the use of magnetite will use less energy throughout the repair process due to its ability to hold heat. The burden on budgets is anticipated to be greatly reduced due to the longevity of the repair and significant savings in energy usage.
