Investigation on the effect of low carbon, low shrinkage, high flexural strength envisia® concrete on industrial floor and pavement application

Industrial, Intermodals/Ports Members Only

The key structural element in most industrial enterprises is the concrete floor slab. The aim of floor design is to select the most economical thickness while considering sufficient reinforcement to control the amount and size of cracks to a level consistent with the intended use of the floor. However, one...

The Case For Lower Strength Gain and Early Age Acceptance of Concrete for Road Pavements

Highways Members Only

The objective of this paper is to encourage informed discussion among concrete pavement engineers. In New South Wales there is a substantial length of contemporary concrete highway construction. A very large inventory of concrete strength results is available. These have shown that construction specification requirements are being significantly exceeded in...

Features, benefits and challenges of air entrained pavement concrete mixes using fly ash (ASCP 5th Conference)

Members Only

The benefits of replacing a proportion of cement with fly ash in concrete mixes have been well understood for many years, particularly in the mitigation of alkali silica reactions. In pavement concrete mixes, however, the properties of fly ash can often play havoc in controlling the amount of air in...

How Runway Pavement Value Choices are Influenced by Construction Costs, Loading, Subgrade and Operational Considerations

Airports, Highways Members Only

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

Highways Members Only

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

Highways Members Only

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

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

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

Highways Members Only

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...
