Optimising Geotechnical Design: Evaluating Hammer Efficiency in Standard Penetration Testing for Enhanced Soil Property Correlations   

The current geotechnical design practices often rely on Standard Penetration Test-N (SPT-N) values without conducting additional, costly laboratory tests. To enhance the reliability of these values, an investigation into the hammer efficiency from various drilling rigs employed by the TMR Geotechnical Section has been undertaken. Utilising the latest Standard Penetration Testing (SPT) Analyzer, this research […]

The Collaborative Project

The Collaborative Project aims to embed ‘collaboration as standard’ by developing and implementing a collaborative procurement and delivery model.  The project, overseen by a joint TMR and industry Advisory Boards aims to operationalise the TMR-Industry Collaboration Charter developed in 2021. To deliver our objectives the Collaborative Project is implementing a systems approach to build in […]

Intelligent Construction – Improving Efficiency and Productivity

Improving the quality of road construction while increasing efficiency and productivity is a key focus for the industry and State Road Agencies. Intelligent construction initiatives including intelligent compaction, asphalt thermal profiling, dielectric profiling systems, 3D profiling are technologies that can help achieve these goals. As compaction is critical for the performance of pavement layers, intelligent […]

Implementation of Contractor Initiated Asphalt Mix Design Innovations on TMR projects

Asphalt mixes that are supplied to Transport and Main Roads (TMR) projects must be submitted for registration prior to use. Mix design registration has historically been limited to mixes that fully conform with TMR specification requirements. To help facilitate the trialling and use of suitable Contractor proposed innovations on TMR projects, Engineering & Technology Branch […]

Reduced Carbon Emission Through High Strength & Lower Carbon Concrete & Design Innovation

Carbon reduction is critical to achieving the Queensland Government’s 2030 renewable energy target and Net Zero Emissions by 2050. The Boral / Beca response to this challenge was to develop a basis of design for a bridge structure that would realise substantive carbon reductions through low carbon concrete and dematerialisation. We developed an evidence-based comparison […]

Management of Structures with Concrete Halving Joints

Poor performance of structural details known as halving joints has been the cause of a number of international bridge collapses in the past 20 years. While the Queensland Department of Transport & Main Roads (TMR) no longer allow these details on new designs, there are a number of legacy structures which must be managed through […]

Animals on or Near Roads App

A Coronial Inquest into two separate deaths on the Bruce Highway north of Townsville in 2015 linked the deaths to local populations of feral horses.  The Coroner handed down a number of recommendations, and identified TMR as the lead agency to develop and implement a Joint Management Plan with key stakeholders, including Townsville City Council, […]
