Construction, Contractor Capability & Innovation: How can we achieve these outcomes in a risk adverse concrete pavements was another successful (ONLINE) event. With over 100 attendees registered and almost 90 joining the event - this forum brought together a range of key experts within the concrete pavement supply chain where each shared perspectives on the challenges, drivers, tools and possible pathways towards increasing innovation and the competitive advantage of concrete pavements.
Carol Enrique Bockelmann Campo opened the forum sharing his 20+ years of experience in pavement engineering and pavement Asset management focusing on Short Jointed Concrete Pavement, Concept, Design, Experiences (Innovation in USA and South America). John Hodgkinson shared his reflections on the past : lessons that can be learned from the publication 'Road Note" a previous publication of the Cement Concrete and Aggregates Australia between 1976-2004. Editors included, John Cruickshank's, George Vorobieff and John Hodgkinson.
Dang Bui (first timer) and Shane Dunstan shared their respective insights in the use of Roller Compacted Concrete (RCC) and innovation. Dang focused on Innovation with RCC Application in NSW, in particular Moorebank IMEX Intermodal Maintenance Transfer Points. Some key learnings shared by Dang were; Roller Compacted Concrete (RCC) is a versatile material; relatively easy to place; readily available; a serious alternative to heavily bound pavements; has considerable contruction program benefits and can be used in many applications. Dang presentation simulated considerable Q&A and was highly rated in the post event survey.
Shane shared a number of studies funded by the RCC Pavement Council (USA) into volumetric density of RCC and jointing and RCC capability within Ports, Intermodal, Factories, Reservoirs, Roads and Streets. Some core observations from Shane's presentation were; unreinforced rigid concrete pavement; compressive strength between; 28 to 65 MPa; flexural strength; 3 to 7.5 MPa; modulus of elasticity; 20,000 to 38,000 MPa; cement content typically 12 to 16% of dry aggregate weight and placed at optimum moisture content for compaction (OMC) to maximum practical density.
Justin Moss using a re-recorded presentation offered a rethink to the design considerations for the Award winning Pathway design. Issues such as; using lower shrinkage concrete; synthetic fibres to replace mesh; improved jointing practices; enhance sublease compaction + erosion resistance and good QC.

James Walker wrapped up the event with an interactive update and demonstration of the rich insights and data you can extract from the Concrete Pavements Map Project.
