VicRoads Micro Surfacing Project Gains Downer EDI Works the 2017 ISSA President’s Award
From November 2015 to April 2016, Downer EDI Works Pty Ltd completed a large scale micro surfacing project that involved work across three separate VicRoads regions, including 43 separate sites, with coordination of individual region priorities and requirements. The primary work was to supply and lay micro surfacing (Type III, 7mm aggregate), with the objective of improving of both pavement ride and shape.
Based on this project’s innovation and complexity, appearance, and consideration of safety, at its 55th Annual Convention in Tucson, AZ, on February 16, the International Slurry Surfacing Association (ISSA) elected to award Downer EDI Works Pty Ltd with the 2017 ISSA President’s Award.
VicRoads manages the arterial road network in Victoria, Australia, and its use as an integral part of the overall transportation system. VicRoads contracted for the use of micro surfacing within their network, with the primary expectation of improving pavement ride and roughness reduction. Single and double coat applications specified targeting this primary goal. In addition, the project sought to improve pavement drainage, provide a uniform final surface texture, and extend the life of the network pavement in an economically effective way.
The complexity of the VicRoads project included the delivery of micro surfacing over geographically isolated locations, involving long haulage distance, lack of suitable stockpile locations, and supplying of potable water given the remote locations. Three separate micro surfacing designs were used for the project. The work included culturally and environmentally sensitive areas, due to works around major tourist attractions, and delivery around peak tourist seasons.
The project involved works on a variety of roads including interstate freeways, significant tourist routes and remote arterial roads. In consideration of project safety, Downer implemented several Zero Harm initiatives including an interactive system to discuss daily risks and hazards with the crew, training in a Red Zone initiative to include a 10 meter exclusion zone around the mobile plant, and implementation of a near miss reporting system.
The project exemplified the criteria of the ISSA President’s Award, showcasing high quality results achieved using micro surfacing to extend and improve the characteristics of their network asset. The contract was delivered on time, within budget, and without any safety or environmental impacts.
Peter Gibbs, Senior Maintenance Officer, VicRoads Northern Region, noted, “Downer’s performance and management of works completed within VicRoads Northern Region on Contract 9193 during the 2015/2016 was of an excellent standard. We were particularly impressed with the innovative pre-start toolbox meeting, where the windows of the staff bus were utilised as a white board for drawing the day’s events and hazards, there for all to see and reference if needed.”
Each year, the ISSA President’s Award is presented to recognize those contracting achievements that best exemplify the highest quality of workmanship and materials, and conformance to best practices as defined by the International Slurry Surfacing Association. Submissions are judged based on customer satisfaction, innovation and complexity, appearance, and safety.
