Low Carbon Concrete – A Future for TMR Structures
The contribution of concrete, and particularly cement, production to global carbon dioxide emissions is well established (roughly 8% of total). In the last ten years there has been a concerted effort to find practical pathways to reduce the carbon footprint of concrete infrastructure but this has led to plethora of options and directions in the […]
Centreline travel on structures by Oversize Overmass (OSOM) vehicles – study of (OSOM) vehicle related crashes
The Revised Class 1 Vehicle Regime Program requires implementation of centreline travel on structures for some Oversize Overmass (OSOM) vehicles to manage structure risk. To consider appropriate risk controls and identification of appropriate pilot and escort arrangements for OSOM vehicles, a detailed study reviewing 16 years of crash data linked to (OSOM) vehicles on the […]
The effective use of traffic control devices to reduce bicycle/e-scooter and pedestrian conflict and improve safety on shared paths and Green Bridges
Shared paths are the most common type of facility due to the cost of constructing separated paths, limitations in the physical area available for a path and the versatility of a shared path, being accessible by all users. Shared paths should be used in situations where there is demand for both a cycling/e-scooter and a […]
Biogenic bitumen the journey to net zero
Over the past two years bituminous road binders incorporating a proportion of biogenic (plant grown) material were introduced in Australia. These binders have significantly reduced carbon footprints, because plants absorb atmospheric carbon dioxide and store the carbon. The carbon bearing plant material is processed into a biogenic bitumen component and blended with conventional bitumen. When […]
Unpacking net zero and the climate emergency for Queensland transport infrastructure projects
Responding to the climate crisis and aligning strategy and investment in the transport sector to net zero has become a preeminent concern. Decision makers and planners are grappling with new and evolving concepts, such as embodied emissions and scope 3. This presentation will ‘walk through’ these concepts, from theory to their practical implications for infrastructure […]
How speed cushions came to be installed at an existing zebra crossing
At grade pedestrian crossings are assumed to have no quantifiable safety benefits in Queensland. Raised pedestrian crossings, on the other hand offer significant benefits. They lower vehicle speeds at the crossing point, reducing the likelihood and consequences of crashes. A Crash Reduction Factor of 63% is assumed in the model parameters for the Austroads Pedestrian […]
Improving safety in a roundabout way: Learnings from the Moores Creek Road, Feez Street and Kerrigan Street intersection upgrade
The Moores Creek Road, Feez Street and Kerrigan Street roundabout is a major intersection on the Rockhampton Regional Council (RRC) network with a long-running crash history, including 21 killed or seriously injured (KSI) crashes in the ten years preceding 2017. An analysis of these crashes and non-injury/property damage only crash descriptions provided by Queensland Police […]
Implementing contemporary sustainabilitypractices to support policy changes (CaseStudy)
In 2019, the Australian and South Australian governments committed $354.3million to construct the Regency Road to Pym Street (R2P) Project as part oftheir overall commitment to build a non-stop North-South Corridor.The project comprises an at-grade motorway from the existing motorwayinfrastructure to the north (South Road Superway); an overpass of themotorway over Regency Road; and an […]
Road Safety and Vehicle Technology Initiatives
The following road safety and vehicle technology research projects and trials have been undertaken in recent years through the road construction industry in conjunction with the Australian flexible Pavement Association (AfPA) to improve the safety of roadworkers in road construction. These initiatives focus on mitigating key risk areas in the road construction industry including plant […]
Assessing load limits through bridge monitoring
Road bridges in remote mining locations are frequented by a wide variety of Heavy Vehicles and Over Size Over Mass (OSOM) vehicles that support the mining industry. Monitoring bridge structure dynamic responses to different loads, vehicle categories, and vehicle speeds participates in providing actionable insights to optimise vehicle load limits, vehicle speed restrictions, and the safety of the bridge structures. A permanent bridge […]
