Our Experience—Transport
Pavements
Often the make or break of new roads or existing road upgrades is, pavement design!
Understanding that every road surface has different needs depending on their intended use, location, and soil structure, our specialist pavement engineers hold an intimate understanding of pavements and materials as well as construction and maintenance practices. Looking at the bigger picture, we consider traffic loads, subgrade evaluation, materials, thickness, climate considerations, and maintenance and rehabilitation needs so we can facilitate the best possible outcomes for our clients and road users. Backed by an extensive knowledge of State Road Authority, Austroads and local council guidelines, our expertise spans from residential and commercial subdivisions to major arterials and freeways, port facilities, mining and renewable energy facility access tracks and intermodal terminals.
Golf Links Road— $39m CIVIL, ELECTRICAL, GEOTECHNICAL, PAVEMENTS, TRAFFIC AND SUSTAINABILITY The upgrade to Golf Links Road aimed to enhance road safety for all road users, featuring improvements to road surfaces, improvements to a six-way roundabout, two cross intersections, installation of traffic lights and a pedestrian crossing near a school, construction of new footpaths drainage upgrades and installation of safety barriers along sections of the road. WGA verified an option to adopt a Foam Bitumen Stabilisation pavement treatment, to increase the amount of existing pavement material that could be reused on site, reducing the quantity of virgin material used in the construction of the pavement. This was a highly sustainable solution and providing significant cost savings to the project, whilst also providing traffic staging benefits.
Hall Road East Upgrade— $42m CIVIL, ELECTRICAL, GEOTECHNICAL, PAVEMENTS, TRAFFIC AND SUSTAINABILITY The Hall Road East Upgrade involved adding an extra lane in each direction between McCormicks Road and Western Port Highway, enhancing five intersections to increase capacity and improve traffic flow, providing new walking and cycling paths, and installing centre median and kerb-side safety barriers. The site featured generally expansive subgrade with swell results ranging from 0% to 2.5%, and isolated sections of high expansive materials exceeding 2.5%. WGA undertook further assessment on the expansive nature of the site and revised the reference pavement design to address these highly expansive subgrade areas while maintaining a practical, cost-effective solution.
Goodwood, Springbank and Daws Roads Intersection Upgrade— $61m CIVIL, ELECTRICAL, GEOTECHNICAL, PAVEMENTS STRUCTURAL AND TRAFFIC
Goodwood Road is one of southern Adelaide’s major north-south arterial routes, with Springbank Road and Daws Road providing a key east-west connection. On average, over 60,000 vehicles a day travel through this location, with travel time delays in peak periods. The upgrade to the Goodwood, Springbank and Daws Roads intersection aimed to address safety and traffic volume issues at this highly travelled intersection. The intersection upgrade consisted of full depth asphalt pavements either constructed over imported granular subgrade replacement material or over existing remnant pavement material. WGA's pavement designs included the use of deflectograph testing to assist with determining the structural condition of the existing pavements and level of upgrade required. Constructibility was a key requirement of the project, along with limiting road closures during construction. This in part included the option of an asphalt working platform that could be installed should thin remnant pavement depths be encountered during boxing out.
