Presentation by Geoff Ayton on design and construction of concrete roundabouts.  

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...

Pavement Type Selection: What is the Ideal Process?

Conf-paper-iscr

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...

A Study of Ground Performance for Rigid Pavement Design: Pacific Highway Upgrade at the Warrell Creek Floodplain

Conference-paper-ascp, Ascp-conference-presentation

The alignment of the proposed Pacific Highway upgrade between Warrell Creek to Nambucca Heads traverses five (5) major floodplain areas underlain by deep soft alluvium sediments. The low bearing capacity and high compressibility of foundation soils were found to attract significant ground settlements, with differential settlements to adversely impact the...

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...

Design Of Ultrathin Fiber Reinforced Concrete Pavements

Conference-paper-ascp, Ascp-conference-presentation

A new methodology has been developed to design the concrete slab thickness by optimizing the slab size given the geometry of the truck axles, the design is based on an unbonded system with either granular, HMA, Stabilized or Concrete Base. The key principle of the design method is to configure...
