Deflections measured using Falling Weight Deflectometer (FWD) device are used to backcalculate the elastic modulus (Epcc) of the concrete slab of a jointed Plain Concrete Pavement (PCP). The two procedures used to estimate the Epcc of the PCP slab from the deflection basins include the AREA method and the Best-Fit...
CSA Concrete Road Slab Replacements A Review of International Practice and Literature
Calcium sulfoaluminate (CSA) cements present an opportunity to improve upon a number of the shortcomings of ordinary Portland cement (OPC). The fast setting and rapid strength gain characteristics of CSA cements have led to a worldwide uptake in the operational maintenance area. The use in road and airfield pavements is...
Local Government Path Paving by the Slip Form Method
Concrete path paving for pedestrian commuting is visibly abundant in all towns and cities especially in the newly establish residential estates across Western Sydney. Primarily the norm is to have the path paving completed by the conventional hand place methods under local government supervision. This paper will outline the trials...
Grated Drain by the Slip Form Method
Over the past 12 years JK Williams Contracting Pty Ltd (JKW) have been slip forming kerbs and guttering, F type barriers, CRCP and residential concrete path paving across Greater Sydney developments. Over the period, we became very aware of a demand for lengthy ACO style grated drains, something which emerged...
Impact of GGBFS Cement on the Interfacial Transition Zone and Influences on Flexural Strength of CRCP Concrete
With an increased focus on sustainability of concrete in commercial and infrastructure projects, the use of alternative cementitious sources is increasing. At the same time the availability of flyash in Eastern Australia is becoming less certain and secure in terms of both quality and future quantity. Transport for NSW specification...
2021 A Subbase Odyssey
The subbase layer has a critical role in the design of concrete pavements. Australia is unique in its routine application of a lean mix concrete subbase layer to much of the heavy-duty concrete pavement highway network, the result of which is a reluctance to adopt any alternative (why fix what...
ASCP2021 6th Concrete Pavements (e)Conference – Proceedings (with video recordings)
Outline 2020 tested our flexural capacity and at times strained our mental tensile strength to 85% yield. To maintain tradition, ASCP has worked hard to develop a unique line-up of papers and delivery format for its 6th Concrete Pavements Conference which was delivered in August 2021. Like previous biennial conferences,...
