Aggregate Industries launch four new asphalts

Company strengthens asphalt offering and offers specifiers more scope with quartet of new products

Aggregate Industries have today launched four new products – SuperLayer, SuperPath, SuperSAMI and SuperCurve – that further bolster the company’s asphalt offering and give specifiers even more scope to find the perfect solution for their specific requirements.

SuperLayer is a specially designed asphalt mix that can be laid in a single lift to form a combined surface and binder course layer, and can also remove the requirement for a regulating course layer. It therefore provides a faster, safer, durable and environmentally sustainable solution to urban, commercial and residential road projects, be they new build or purely maintenance.

SuperPath is a fast, single-lift, durable and environmentally sustainable solution that replaces traditional two-course construction on urban, commercial and residential footway and cycleway construction projects. The single application means it can be applied quicker, reducing disruption to the public. It is well suited to footways and cycleways thanks to its excellent load bearing capability whilst maintaining surface texture.

A stress-absorbing membrane interlayer (SAMI), SuperSAMI can be used where reflective cracking is a problem, for example to overlay jointed concrete carriageways or on hydraulically bound mixtures in flexible composite pavements prior to installing binder and surface courses. Fully recyclable SuperSAMI is highly fatigue and crack resistant, workable and easy to lay and compact, with no special equipment required to lay it.

SuperCurve is a high-performance 10mm polymer-modified asphalt surface course designed and engineered to provide enhanced performance for more heavily trafficked and stressed road carriageways areas, such as roundabouts and junctions. It offers an alternative to standard hot-rolled or chip asphalts, which saves on the cost of a chipping gang. It has been developed in order to meet the Specification for Highway Works clause 942 and can be formulated to meet that standard at the specifier’s request.

Commenting on the new products, Chris Hudson, managing director of asphalt at Aggregate Industries, said: ‘We’re delighted to launch these four new asphalts, each offering a particular set of benefits for a wide array of applications. Our focus, as ever, is on providing our customers with the right product for the job, while offering convenience and sustainability as standard.

‘Furthermore, SuperLayer, SuperPath and SuperCurve can all be offered in our SuperLow configuration, which gives specifiers the option of reducing the carbon impact of their asphalt of choosing all the way to carbon neutral.’

SuperLow, which launched in October this year – is the market’s first carbon-neutral asphalt solution. It features reduced carbon levels when compared with standard asphalt as it is manufactured at reduced temperatures. All remaining emissions are then offset through carbon-reduction projects, on the customer’s behalf, through Aggregate Industries’ offsetting partner, Circular Ecology, all without any change to product performance.
