ASCP Forum (Online) – Tunnels Pavements, Concrete Supply, Procurement – Tuesday 12 April 2022

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

Tunnels allow rapid and unobstructed transport facilities in big congested cities. Think the recent NorthConnex! Whilst considered an expensive solution, tunnels provide a protected system for the pavement, thus tunnels reduce the maintenance cost of the system, but there are wider considerations in the design, detailing, materials selection and construction...

Sydneys Western Freeway (Mar 1983)

Cca-road-note

On 16th December 1982 the Hon. Neville Wran, Premier of New South Wales, opened two new sections of the F4 Western Freeway near Sydney. The comibined length of almost 9 km is made up of 5.8 km between Strathfield and Silverwater, and 3 km between Parramatta and Mays Hill Figure...

Continuously Reinforced Concrete Pavements (Mar 1992)

Cca-road-note

Continuously reinforced concrete (CRC) pavements have the feature that the longitudinal reinforcement is continuous for the entire length of the pavement. Other than end-of day construction joints there are no transverse joints in CRC pavements. By balancing concrete properties, thickness and the amount of reinforcement, fine transverse cracks are developed...

Crcp (Apr 1980)

Cca-road-note

A continuously reinforced concrete pavement (CRCP) is structurally stronger than a conventional reinforced concrete pavement and requires no transverse contraction joints, thus ensuring lower maintenance costs and excel lent riding qualities. Since June 1976 the Department] of Main Roads, NSW has completed three continuously reinforced concrete pavements, one in a...

ASCP Forum – Pavement Maintenance and Upgrades, Annual General Meeting, Occasional Speaker, Inaugural Industry Awards Evening

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

With an eye to future rehabilitation solutions, John Hodgkinson re-visited a CRCP overlay constructed on the Hume Highway, just north of Holbrook, in 1992. A significant milestone was reached in June 2021 as the first BCSA Rapid Set Concrete slab celebrated its 10th Birthday in Australia at Sydney International Airport. Since this...

Active Crack Control for Continuously Reinforced Concrete Pavements (CRCP) In Belgium Through Partial Surface Notches

Technical-report

Recent field observations on several newly constructed Continuously Reinforced Concrete Pavements (CRCP) in Belgium have indicated that the crack pattern is characterized as low mean crack spacing (approximately 1.0 m after 2 years in-service) along with a high percentage of clusters of closely spaced cracks. Besides, field surveys also indicate...

ASCP Forum (Online) – Specification Updates, Are You Trusted?, New Exec Director, Open Mic

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

Concrete is used throughout the World every day in countless diverse applications but it is critically important in terms of performance and durability to understand why the mix design and placement need to be appropriately tailored to suit each application. The inimitable Geoff Ayton will explore what it takes to...

Impact of GGBFS Cement on the Interfacial Transition Zone and Influences on Flexural Strength of CRCP Concrete

Conference-paper-ascp, Ascp-conference-presentation

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...

Investigation of Crack Width Development in CRCP

Conference-paper-ascp, Ascp-conference-presentation

The traffic volume on German motorways increased steadily and this trend is expected to continue in the future. To guarantee mobility in the future and reduce the national economic consequential costs, road construction with a maximum service life and a minimum of necessary maintenance are needed. Rigid road pavements with...

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,...
