Partnering for innovative solutions in concrete paving: A tour of a few key concrete states in North America


Tim Nash presents on Partnering for innovative solutions in concrete paving. The presentation covers: General overview of US concrete paving market (Covid effect, spending outlook and market characteristics) Paving manufacturer focuses (mold design, frame/chasis design, control systems, attachments) Discussion of various recent projects (Interstate, local roads, safety barriers)

Macro Synthetic Fibres – Potential Uses in Pavements [MSFRC]


Presentation Overview What are Macro Synthetic Fibres Review of Current Practice (Global, National, Domestic & SRAs/DoTs) Current and potential applications Recommendations What are Macro Synthetic Fibres? Available commercially since the early 2000s Intended to be used as a replacement for steel mesh reinforcement and not for structural steel design. Manufactured...

ASCP Strategy 2021


This document sets out the strategic themes to be focussed on in 2021. Updates 15th June 2021: Sustainability elevated in importance Upgrades renamed "Renewals" (pending review by NE)

Pavement Type Selection: What is the Ideal Process?


Pavement type selection is often one of the more challenging and controversial decisions highway administrators face. The process involves weighing engineering factors such as materials, structural, and even long term performance against initial and life-cycle costs to help agencies decide between various pavement alternatives. Given the expenditure of significant public...

Application of a Shrinkage Reducing Agent (SRA) in Concrete Pavements

Conference-paper-ascp, Ascp-conference-presentation

SRAs have been used in concrete in Australia since their introduction into the marketplace in the mid1990s. However, its recent application in a major road project in NSW has generated interest from Government bodies, engineers and contractors within this sector of the construction industry. The author therefore wishes to discuss...

Performance of Silicone Sealants in Sawn Joints

Conference-paper-ascp, Ascp-conference-presentation

Concrete pavement joints are required to be sealed to prevent the ingress of debris, mainly incompressible and water. In the year of 2012, there are a number of reports of pavement joint sealants losing adhesion within the first 5 years of service and eventually being mostly depressed under the wheel...

The Performance of Low Noise Diamond Grinding (LNDG)

Conference-paper-ascp, Ascp-conference-presentation

Conventional diamond grinding has been used in Australia since 2010. The purpose of diamond grinding is to improve ride quality and shape, reinstate service texture and reinstate skid resistance. This presentation reports on trials of low noise diamond grinding in NSW, Australia with analysis of performance monitoring results and comparison...

RONDA – Pavement Noise Measurements on Concrete Roads

Conference-paper-ascp, Ascp-conference-presentation

Road traffic noise affects approximately 8 million people in Australia with 2 million seriously affected, far more than from other forms of transportation. As the principal source of road noise is from the tyre/pavement interface and, given that concrete pavements are preferred by many road authorities due to its hard...

Merits and Challenges of Increasing Limestone Addition in Cement Used in Concrete Pavement Construction

Conference-paper-ascp, Ascp-conference-presentation

Portland cement has undergone much change in recent decades to cater for rapid construction cycles, longer design life and environmental pressure. Increased fineness, the advent of Portland blended cements incorporating one or more supplementary cementitious materials (SCMs), and reduced clinker content via mineral addition have been the key technological solutions...
