In Australia, most runway pavements are constructed from asphalt, however the reverse is markedly true for the USA. Melbourne’s Essendon runway was originally concrete but was overlaid with thick asphalt many years ago. Asphalt runways at Melbourne’s Tullamarine and Amberley have some sections of concrete. This paper explores the determination...
Influence of Ground Granulated Blast Furnace Slag (GGBFS) Cement in concrete pavement mix designs
Roads and Maritime Services (RMS) pavement specifications require the use of Grade 1 fly ash and Ground Granulated Blast Furnace slag cement (GGBFS) for R82 – lean mix concrete subbase [1], and also fly ash and/or GGBFS for R83 – Concrete Pavement Base [2], where reactive aggregates are used. This...
Getting the Most from Roadway Investments
Roadways & pavements play a vital, but underappreciated role in our nation’s economic competitiveness. Implementation of two policies can improve the pavement network investment efficiency; Introduce more competition into the pavement bidding process Use “Remaining Service Interval” concept to allocate resources effectively at the pavement network level Together, these policies...
The important role materials play in concrete pavement design, performance, and service life
The materials that make up concrete have a direct influence on the decisions made during pavement design and construction, as well as the performance of the pavement in service. What happens when material performance varies from what was considered at design stage? What if we need to change construction methods...
A Fresh Look at Pavement Life Costs
Whole of life cycle costing of pavements has not been revisited for nearly 27 years since 1990 by the Bureau of Transport Economics (now BITRE). Previously, asphalt pavements were considered to have a lower cost of construction but required regular maintenance (every 5 to 10 years) whereas concrete pavements are...
The Future of Concrete Pavement Imagined
Transformational change is underway, so what does the future hold for concrete pavement? How is transportation of people and goods likely to change in the coming decades as population grows, mobility needs change, climate change advances, and transportation technology evolves? What are the market dynamics that will shape our industry...
