1 LOW The ultimate solution for faster completion and carbon footprint reduction AGGREGATES AND ASPHALT

2 Pressure from road users to keep busy roads moving and requirements for higher standards of safety and sustainability are driving the adoption of innovative, high performance asphalt solutions. For many project managers, low temperature asphalts offer a valuable combination of faster completion times, lower costs and improved sustainability that can help them meet even the most demanding project requirements. FINISH ULTILOW is a range of low temperature asphalts, manufactured and supplied to comply with TRL Report PPR 666, within the Warm Mix category. ULTILOW asphalts use proven technology to ensure that the material supplied performs as well as conventional hot asphalts, but with the added benefits of enhanced workability, improved sustainability and earlier reopening times to traffic.

3 benefits Ultimate Speed ULTILOW is supplied at temperatures typically 40 C lower than a hot equivalent, reaching appropriate trafficking temperatures quicker than hot asphalt for earlier reopening of carriageways. This feature is particularly valuable when thick construction layers are necessary. How it works ULTILOW is produced by either foaming the bitumen or by using a warm mix additive during manufacture. Ultimate Convenience Faster construction times keep busy roads moving, minimising disruption to road users. Ultimate Productivity Where time is restricted, larger sections of pavement can be laid and still opened to traffic as required, reducing the overall contract programme duration and potentially reducing plant, labour and traffic management costs. Ultimate Availability ULTILOW is not seasonal and can be supplied and laid all year round. Ultimate Sustainability ULTILOW asphalts deliver carbon footprint savings compared to hot equivalents. Ultimate Safety Lower temperatures mean less risk of burns and reduced fumes and steam on site, which can sometimes impact on visibility. This is particularly evident during cold and /or wet weather and during night shift operations. The ULTILOW range is based on tried and tested technology that is proven to deliver equivalent performance to conventional hot asphalts on key performance criteria. Bitumen foaming is when a small quantity of water injected into hot bitumen becomes converted into steam. The bubbles of steam create a foaming effect which increases the volume of the bitumen, temporarily reducing the viscosity and making it easier to fully coat the aggregate. Warm Mix additives are designed to reduce the surface tension of the bitumen itself, allowing the mix to be manufactured and compacted at lower temperatures. Both processes produce comparable warm mix products, for enhanced workability and earlier completion times. ULTIMATE SPEED ULTILOW reaches appropriate traffic temperatures quicker, so roads can be opened earlier, reducing delays and disruption.

To ensure our customers get the best possible results, expert support is never more than a phone call away Typical Applications ULTILOW is generally available as an alternative to the full range of conventional asphalts with the exception of a Hot Rolled Asphalt Surface Course that requires the application of pre coated chippings. This exception is due to the inability to effectively heat the bitumen on the pre coats at the lower temperature and ensure adequate bond with the HRA.

5 EXPERIENCE Derbyshire County Council, Newshaw Lane, Glossop Challenge Derbyshire County Council were looking for alternative materials to help meet their challenging targets for reducing carbon footprint. In this case another key consideration was minimal public disruption outside the Glossopdale Community College where access had to be maintained. Solution ULTILOW warm mix asphalt was supplied as a 20mm dense binder course and a 10mm close graded surface course subsequently applied shortly afterwards before re-opening to traffic. Result ULTILOW warm mix asphalt achieves savings in greenhouse gases through the lower manufacturing temperature and also allowed the road to be opened to traffic sooner than with conventional hot mix materials. Traffic was flowing on the new surface only 30 minutes after completion of surfacing. Highways Agency / AOne+, A46, Cossington Leicestershire Challenge The Highways Agency requested a demonstration installation site be supplied with Low Temperature Asphalt to demonstrate business as usual in terms of site operations and equivalence of product performance compared to hot mix equivalents. Solution The materials specified in the contract were a 20mm dense binder course 40/60 pen to clause 929 and a 14mm thin surface course to clause 942. ULTILOW solutions are available for most requirements and the 20mm dense binder course and UltiPave 14mm clause 942 surface course were produced in both hot mix and warm mix versions. Areas of the base layer requiring reconstruction were planed out and Lafarge Tarmac s UltiFoam cold recycled base solution was also manufactured from the road planings. Result The site was supplied without issue or any need to adjust normal site practices. Testing carried out on both the hot mix and the ULTILOW warm mix materials, demonstrated that equivalent performance can be achieved for all the specified parameters such as surface texture, voids and resistance to rutting.
