Maturity testing of concrete, and applications for concrete pavements will be explored by Sabrina Garber from Transtec (USA). On a recent motorway project in Sydney roller compacted concrete was adopted as a working platform for pavement construction on local government roads. The successes and lessons learnt will be explored by...
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,...
Pavimentos de Hormigón Con Bajo Nivel de Ruido (Pavement Note 003) [Spanish, español]
Texturizado Suave, Seguro, Duradero y Rentable (LDNG) Las administraciones que gestionan infraestructuras viarias quieren pavimentos con bajo coste de construcción inicial, bajo coste de mantenimiento, buena resistencia al deslizamiento, especialmente en clima húmedo 1, buen confort y calidad de conducción y bajo nivel de ruido. El LNDG cumple con cada...

ASCP Forum – Sustainability- Mecla, Westconnex 3b Rozelle & Slab Replacement
The objectives of MECLA and why cutting embodied carbon matters will be put forward by Hudson Worsley. How MECLA came to be set up, the findings of its foundation research, who is involved, how it works and what it hopes to achieve will be addressed. Veronica Prado, Timothy Cook and...
ASCP Forum – Maintenance of Concrete Road Pavements – Specifications & Materials
Sydney has a very large network of State and Local Government concrete roads built from the mid 1920s to the 1950s. There is an increasing need for slab replacements, but with worksite access typically limited to a single night shift. Using CSA rapid set cement, there are now 12 years...
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...
New Developments in Rapid Set Concrete Slab Replacements
Current and future eras are seeing an operational environment where road occupancy for pavement maintenance or repairs will be severely restricted under conditions of maximising availability for service traffic and access to roadside properties. A key driving force for concrete pavement slab replacement, where required, is the need to use...
Latest Developments for Roller Compacted Concrete (RCC) in USA
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by a high density paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards and manufacturing plants. This paper will summarise a recent...
Pavement Design Methodologies for Port and External Heavy Duty Pavements
There are few methodologies for the structural pavement design of port and external heavy duty pavements. Traditionally, the pavement design of heavy-duty pavements has been considered a high risk area due to the high proportion of failures and their cost implications (operational and repair). Due to the lack of specific...
Joint Free Restrained Slabs – SFRC combined with mesh
Controlling cracking to acceptable levels in concrete structures requires accurate detailing and good construction practices. This is more prevalent in ground supported slabs that are typically detailed to avoid cracks occurring under service stresses. Detailing the slab to avoid these cracks puts a number of limitations on the floor design...
