The UK-based company says that the four asphalts - SuperLayer, SuperPath, SuperSAMI and SuperCurve - will give specifiers more scope to find the appropriate 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. Aggregate Industries says that 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 designed to be a fast, single lift, durable and environmentally sustainable solution replacing traditional two course construction on urban, commercial and residential footway and cycleway construction projects.
The single application SuperPath means it can be applied quicker, enabling reduced disruption to the public. It is ideal for footways and cycleways thanks to its excellent load bearing capability whilst maintaining surface texture.

SuperSami is a stress absorbing membrane interlayer (SAMI) that 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. Aggregate Industries says that SuperSAMI is fully recyclable in addition to being 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.  According to Aggregate Industries it offers an alternative to a standard hot-rolled or chip asphalt, 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, MD 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.”
The SuperLow carbon-neutral solution launched in October this year and is claimed to feature reduced carbon levels when compared to standard asphalt as it is manufactured at reduced temperatures. Aggregate Industries says that 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.
