Beveridge Road Thornlands is a section of road in Redland City Council becoming completely submerged during significant rainfall events and retaining large pools of stranded water throughout the year.  The road leads to the Redland City Marina.

A section of the road was raised by using two layers of asphalt composition. Both asphalt mixes were made with Entyr eCB and eDTH in the processing.  The new asphalt will significantly improve the surface texture rut resistance of the road.  The surface texture of the asphalt will increase the skid resistance of the road surface especially during rain events.

The Brays Road/Lavender Drive roundabout in Griffin is subject to high volumes of traffic accessing residential settlements, small businesses, and essential social infrastructure facilities.

The pavement surface was worn and a potential accident hazard due to reduced surface texture. The pavement was removed and replaced with an asphalt mix modified with Entyr’s eCB to deliver skid and rut resistant asphalt with superior strength and fatigue resistance.

September to November 2020

A collaboration between Norwell Motorplex, Austek Road Services and Entyr resulted in critically failed areas of the Norwell racetrack surface being replaced with Austek’s Carbon based products created using Entyr’s recovered carbon black (eCB) in the mix and tyre-derived hydrocarbon (eTDH)  in processing.

The Norwell Motorplex brief was simply for their Super School cars to enjoy a faster and safer surface, but also requiring “the surface to stand the test of time” and be cost effective.

End-of-life racing tyres were used from the racing track and repurposed in the carbon-based asphalts laid at the track.

Norwell Motorplex also has a commitment to find an environmentally positive solution for used race tyres at the completion of their life.

Using both Carbonphalt and Carbonmastic, 400 metres in total of Norwell’s racing track was resurfaced with both product applications. In a 2022 assessment of the performance of these carbon-based asphalts at track showed superior colour retention, a high level of skid resistance and increased scuffing resistance.

King Street, Clontarf, Moreton Bay Regional Council

Moreton Bay Regional Council required a large section of King Street to be resurfaced due to basecourse failures – the road is a busy connector route and a main thoroughfare for local traffic.

The high demand on the pavement required an asphalt solution which would provide superior performance but also be cost competitive and with minimal carbon emissions in its production and application.

The existing pavement was resurfaced using an asphalt mix -created using Entyr’s recovered carbon black (eCB) the mix and tyre-derived hydrocarbon (eTDFO) in processing.

July 2021

In collaboration with the City of Logan and Tyre Stewardship of Australia – Austek Road Services conducted a side-by-side comparison of traditional asphalt against their Carbonphalt (created using Entyr’s recovered carbon black (eCB) and tyre-derived hydrocarbon (eTDH) ).   The project aimed to highlight the contract in performance and benefits between Austek’s Carbonphalt and a similar conventional asphalt mix product.

Both asphalts were laid on Miller Road in Logan Village – a rural access route which serves as an important link between a state controlled main road and residents of rural properties. Millar Road is also frequented by heavy vehicles serving nearby quarries.

The project stretches over 410 m on Miller Road across both carriageways. The first 210 m was paved with conventional asphalt mix and the remaining 200m with Carbonphalt.

Performance of the asphalt will be monitored over time, but it is expected that the Carbonphalt will outperform the traditional asphalt, will have a longer service life and stay blacker for longer.  Feedback from the asphalt laying crew was that Carbonphalt offered a much higher level of workability and ease of construction compared to the conventional asphalt.

The City of the Gold Coast required resurfacing of a roundabout in an increasingly busy built up residential area. The roundabout services homes, schools, a hospital, and major local shopping centres. The heavy vehicular traffic included several bus routes and commercial trucking.

The project brief was to replace the existing asphalt surface with asphalt that would wear well, decrease skidding and improve safety as the roundabout was also prone to accidents.

The existing pavement was removed and replaced -created using Entyr’s recovered carbon black (eCB) in the mix and tyre-derived hydrocarbon (eTDFO) in processing.

Outcomes included improved safety, improved strength, increased colour duration, improved noise reduction, improved skid, and rutting resistance to this heavily used roundabout in Robina, Gold Coast.

AfPA and IPWEAQ both recognised the safety and sustainability of the work completed on this project with prestigious individual industry awards to the asphalt company, Austek Road Services.

December 2021

A high trafficked industrial t-intersection in the City of the Gold Coast required resurfacing with a durable, safe and superior asphalt. The intersection of Geary Crescent and Jade Drive – situated in an industrial precinct of Molendinar – had been well worn, cracked and aged. The route is subjected to both heavy and light vehicles and is also impacted by extensive hooning activity with the pavement prone to degradation from burnout activity, skid trails and other destruction.

The existing asphalt was removed and replaced by an asphalt product created using Entyr’s recovered carbon black (eCB) in the mix and tyre-derived hydrocarbon (eTDH) in processing.

Outcomes from this asphalt has been improved safety and strength, increased colour retention, noise reduction and skid and rutting resistance.

February 2022

Queensland Department of Transport and Main Roads via an infrastructure services provider Ventia, needed to remove the existing failing asphalt on Springbrook Road, a high trafficked tourist road set in a challenging mountainous terrain.

The existing pavement was worn, slippery and dangerous. The requirement was to replace the road with a durable high skid and fatigue resistance asphalt.

A small-stone Stone Mastic Asphalt (Carbonmastic 7mm) was modified using Entyr’s recovered carbon black (eCB) and created using tyre-derived hydrocarbon (eTDFO). In addition to the replacement criteria, the asphalt solution improved sheer road strength, increased colour duration, noise reduction and environmental benefits.
