Project Case Studies
At Roadways, we have been building Tasmania’s roads and
infrastructure for over 60 years.
Our expertise extends across public and private roads, hardstand areas, car parks, and subdivisions, ensuring that every project we undertake is completed to the highest standards.
Hobart City Council CBD Surfacing Program
Client: Hobart City Council
Location: Hobart CBD
Year: 2018
Program of complex roadworks on high-profile, high traffic-volume sites in the Hobart CBD. Works included: service locations; excavation; removal of redundant tram lines and sleepers; survey and design of pavement levels; removal of existing pavement to a nominated depth of 300mm and replacement with multiple deep lift asphalt layers; replacement and
adjustment of stormwater infrastructure to match new surface; and installation of PMB asphalt wearing surface.
The site contained a number of logistical issues – underground services and adjoining local residents who were kept fully informed throughout the works. Traffic through out the site had to be maintained during daylight hours, meaning crews were required to hit pre planned targets to achieve desired results, works were completed more efficiently than originally programmed.
Works were undertaken between 7pm and 5:30am, with tramlines and line marking reinstated at the end of each shift to ensure all lanes of traffic were open to the public by 5:30am.
Supply and Lay Asphalt Program
Client: Glenorchy City Council
Location: Glenorchy Municipality
Year: 2018 – 2021
This project involved pavement repair, milling of existing surfaces, provision of waterproofing and PMB seals and laying of asphalt overlay. Traffic management and reinstatement of line marking was also required.
Roadways worked collaboratively with Glenorchy City Council to develop innovative solutions to project requirements, resulting in the installation of recycled glass asphalt mix to the Sunderland Street road upgrade.
Hollow Tree Road Upgrade – Stabilisation Program
Client: Central Highlands Council
Location: Hollow Tree Road, Central Highlands Municipality
Year: 2018
This pavement stabilisation project involved stabilisation of 3500m2 of patching over 28.8km of rural road. Stabilisation was undertaken to a depth of 150mm depth with 2% cement. A two-coat final seal was designed inhouse in line with the Austroads seal design method and applied to the prepared pavement.
This project introduced a treatment new approach for the municipality, resulting in a client saving of 50% from the mill and fill option. Relevance This project involved roadworks in a rural location, chemical (cement) pavement stabilisation, re-preparation of pavement seal, re- establishment of table and site traffic management.
Lake Secondary Road Dig-out and Repairs
Client: Department of State Growth
Location: Lake Secondary Road, Hunterstone
Year: 2018-2019
This project was undertaken to repair 1150m2 of pavement at SS24 on Lake Secondary Road following pavement failure due to the presence of spring. It involved excavation to a depth of 300mm to remove the failed pavement; installation of geofabric and subsoil drains; deepening of table drains; and placement of half and full road patches in line with DSG specifications.
The project site contained unstable subgrade, with an active spring both under and adjacent to the road pavement.
Sandy Bay Road Resurfacing York Street to Waimea Avenue
Client: Hobart City Council
Location: Hobart
Year: 2019
These resurfacing works involved the removal of old asphalt and concrete to designed levels and replacement with 3600t of A10E asphalt over a three-week construction period. As part of project works, Roadways adjusted and replaced stormwater infrastructure to match
new design surface level. Careful traffic management was undertaken to ensure two-way traffic was maintained throughout the project works.
This project involved night works in a very high traffic volume residential location, with traffic flows required to be maintained at all times. Building condition reports were undertaken at the commencement of the project as a physical record of any pre-existing structural damage to the surrounding residential buildings.
DSG Road Specific Maintenance Pavement Resurfacing, South
Client: Department of State Growth
Location: Southern Tasmania
Year: 2019 – 2020

The program of works included pavement repair, milling of existing surfaces, provision of C170 and PMB seals, asphalt overlays and the reinstatement of line marking.
The delivery program was spread across the available performance period rather than delivering works more intensively in smaller allotments of time. This meant any minor operational delays and disruptions could be absorbed into the available contingency time,
resulting in successful and timely completion of the program.
Mount Wellington/kunanyi Pinnacle Carpark
Client: Hobart City Council
Location: Mount Wellington/kunanyi
Year: 2019
This project involved the design, coordination and installation of 540t of stone mastic asphalt over the existing surface of an alpine carpark in extreme temperature conditions. Careful traffic management and logistics were required for the 4.5m-wide, 13km-long mountain road.
