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...
The Case For Lower Strength Gain and Early Age Acceptance of Concrete for Road Pavements
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...
Investigation on the effect of low carbon, low shrinkage, high flexural strength envisia® concrete on industrial floor and pavement application
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...
