tamborine oxenford road pavement rehabilitation

Ventia Boral Amey (VBA) Joint Venture

Wongawallan, Qld

$1.8 million

Mt Tamborine is a major tourist attraction, with a vibrant village including restaurants boutique accommodation, wineries, markets and a variety of shops. In May 2018 ALLROADS were awarded the contract by the Ventia Boral Amey (VBA) Joint Venture to undertake a pavement rehabilitation contract for one of the main access roads, Tamborine Oxenford Road.

 

The initial scope of works included:

  • Profiling existing road surface to depth of 20mm,

  • Installation of pavement drain,

  • Construction of 2.3 corrector pavement layer,

  • Construction of 2.1 basecourse pavement,

  • Construction of double/double spray seal,

  • Installation of road furniture including guardrail and signage,

  • Concrete kerb and channel and pavement/footpath,

  • Line marking.

 

The steep and undulating nature of the road meant that it had to be constructed in stages, significantly reducing productivity and increasing traffic control requirements. The smaller work zones also meant additional mobilisations for profiler and seal crews.

 

During construction additional works were identified including the replacement of the existing cross culverts beneath the road, reconstruction of the undermined swale drain and rock batter stabilisation which included raking away loose material and installation of a rock protection fence to prevent rocks falling onto the new road.

 

ALLROADS worked in conjunction with VBA ensuring that the works had a minimal impact on stakeholders. Sufficient traffic control was vital in order to manage the high traffic volumes due to the general popularity and frequent events on the mountain. All residents within the work zone were also continuously consulted ensuring their safe ingress and egress from site when leaving their homes.
