CLIENT

Ventia Boral Amey Joint Venture

COMPLETED

January 2019

LOCATION

Bromelton

Engaged by Ventia Boral Amey Joint Venture, Geleon were responsible for coordinating and undertaking the pavement investigations, as well as providing detailed design and engineering services for rehabilitation of the pavement on Beaudesert - Boonah Road at Bromelton, west of Beaudesert. The project was being undertaken as part of the Road Asset Management Contract (RAMC) for the Department of Transport and Main Roads (TMR) South Coast Region. 

Adopting a mechanistic design procedure for the pavement design process using CIRCLY Pro (Version 6.0), three rehabilitation treatments were identified as suitable for investigation based on the guidance provided in TMR's Pavement Design Supplement and Pavement Rehabilitation Manual, which included:

  • Option 1 - Asphalt over granular pavement

  • Option 2 - Asphalt over insitu foamed bitumen stabilised base pavement

  • Option 3 - Cementitiously modified base with sprayed seal or asphalt surfacing.

A preferred option was selected based on cost and constructability factors with construction of the rehabilitated pavement completed in July 2019.
