The DVD contains three discrete videos, each of about 12 mins, and which cover: - Paving & finishing - Making & delivering concrete - Compaction The DVD can be purchased for $20 via the RTA contacts listed on the attached graphics.

CP Tech Center Who we are How it’s paid for What we do What we produce Current projects Who can benefit   Vision Uniting agencies, industry, and universities to advance concrete pavements through research and technology.   History  Started in 2000  Center for Portland Cement Concrete Pavement Technology...

George Vorobieff presents on a planned trial for wet on wet no fines concrete base pavement. The presentation covers the background of no fines (or porous) concrete pavement, including discussion on low noise pavement options. Hand placement and slipformability trials have been undertaken as part of the Northern Hume Alliance,...

What is in the IMCP Manual? 1. Introduction Why bother reading this manual? 2. Pavement Design What will the pavement look like? 3. Materials What materials do I have to work with? 4. Chemistry of Hydration What happens during the formation of the concrete matrix? 5. Critical Properties What do...

Jim Grove (Federal Highway Administration), Dr Jim Cable (Cable Concrete Consultation) and Dr Peter Taylor (National Concrete Pavement Technology Centre) present on improving concrete patching practices. Areas covered included: Strength focus - are we neglecting durability Why do we patch? How long should a patch last? Opening strength requirements Thickness...

David Dash presents on tye road noise for concrete pavements. His presentation covers: Understanding noise: Pressure/power Frequency Filters Measurement and standards Noise spectra Recent results for varying pavement types Concluding that negative texture, such as that achieved via diamond grinding and longitudinal tyning may be preferable for concrete pavements.

The presentation on Cold Weather Paving contains research information which is not yet approved for release. We hope to be able to load that presentation in the near future

A brief analysis of current MoDOT specified limits on gradations was undertaken. Depending on which side (fine or coarse) the gradations were running in relation to the limits, various combinations of sand and coarse aggregates A, B or D were all over the Coarseness Factor chart, with behaviour ranging from...

This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. The video demonstrates the use of an innovative machine to effect concrete pavement jointing.
