ASCP2021 6th Concrete Pavements (e)Conference – Proceedings (with video recordings)

Conference-paper-ascp, Conference-report, Ascp-conference-presentation

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,...

ASCP Forum – Sustainability- Mecla, Westconnex 3b Rozelle & Slab Replacement

Ascp-forum-presentation, Aspcp-forum-on-demand

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

Aspcp-forum-on-demand

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]

Ascp-forum-presentation

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

Conference-paper-ascp, Ascp-conference-presentation

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

Conference-paper-ascp, Ascp-conference-presentation

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

Conference-paper-ascp, Ascp-conference-presentation

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

Conference-paper-ascp, Ascp-conference-presentation

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...

Continuously Reinforced Concrete Pavement Terminal Design

Conference-paper-ascp, Ascp-conference-presentation

In rigid (concrete) pavement design and construction the word “terminal” is used to describe the termination of a concrete pavement abutting other “structures” such as a flexible pavement, a bridge abutment, or another concrete pavement where structural continuity is impractical or undesirable. A discontinuity in grade caused by the differential...
