Value:
$700K

Client:
Dooval Constructions / QTMR Metro

Details:

The scope of the project was re-alignment, widening and re-shaping the Centenary Highway to provide better traffic flow and rideability. The project consisted of a full grid pick up of existing levels by a survey to provide detailed paving plans throughout the sub layers. Profiling was required to remove fatigued SMA and seal membrane, along with deeper design milling, as per design plan. Then place multiple lifts of DG20HM, to conform to MRS 31 specification. Design level to 100mm below FSL was achieved; binder layer of 50mm applied followed by an S4.5S seal to MRS11 specification. Wearing course of SMA14 (MRSS548 specification) placed by travelling reference beam and material transfer vehicle, to achieve rideability and FSL.

 

Cedar Pocket Rd Jimboomba QLD - Foamed Bitumen Stabilisation

RPQ division:
TRICO Asphalt

Project date:
September 2015

Client:
Logan City Council

Details:

The project site was part of road upgrade project that was being completed by Logan City Council to accommodate future residential growth in this area.

This was completed in 3 days.


Chinchilla Airport Rehabilitation and associated works

RPQ division:
RPQ Spray Seal

Project date:
July 2015

Value:
$400K

Client:
Ostwald Bros  / Western Downs Regional Council

Details: 

RPQ Spray Seal undertook our first Airport Spray Seal project in conjunction with Ostwald Bros first full Airport rehabilitation project. RPQ’s contribution to the project was to design and apply a three coat seal incorporating a 14mm & 7mm C170 Double/Double seal and then applying an Emulsion based third coat with a processed sand.
The sand was required to be entirely dry to allow for the successful application of the product to the emulsion binder, this was achieved by transporting a course sand to the Swanbank Asphalt plant and then processing the sand through the plant until completely dry, the final product was then transported to the jobsite where it was protected from the elements until used.
The seal design required an increase in both Binder and Aggregate application rates due to the unique traffic effects of light aircraft, the construction process involved trialling the application rates to ensure that theory worked in practice. To ensure that the intended result was achieved we relied on the input of RPQ Group’s CEO Wayne Boston who has extensive experience in Airport Pavements and Craig Halliday from the Airport Consultancy Group.
The end result is a sealed surface that elicited commendation from the principal and local authorities alike.

Pacific Highway - Farlows Flat NSW - Foamed Bitumen Stabilising

RPQ division:
TRICO Asphalt

Project date:
January 2012 – March 2013

Client:
RFS / RMS

Details:

The project site is located immediately south of the Harwood Bridge (Clarence River) on the Pacific Highway. The initial scope of the Farlow’s Flat project was to raise the existing height of the road pavement above localised flood levels. In some areas of the project this would equate up to approximately 1.5 meter increase in the pavement height from the existing road surface level. Additional work also included the upgrade and re-alignment of South-bound and North-bound access ramps to the Pacific Highway for the Maclean – Yamba interchange..

Road Fleet Service (RFS) was the contractor awarded the delivery of the Farlow’s Flat project. RFS is the construction and maintenance delivery arm of the New South Wales Roads and Maritime Service (RMS). An alliance between the client RMS and RFS was established to administer the delivery of the project. TRICO Asphalt was invited as the sub-contractor to provide foamed bitumen stabilisation of the roadbase used in this challenging project as the highway had to be raised under the live traffic of 14,000 vehicles per day with over 30% heavy vehicles.

The foam bitumen stabilised roadbase proved highly successful and the scope of the project was increase with another 2 stages of adjoining sections of the Pacific Highway included. In the end over 64,000 tonne of foam bitumen stabilised roadbase was used in the 3 stages of the project. Within 12 months of the completion of the project, the site has been flooded twice and the pavement has held sound  performing exceptionally well with no damage despite being submerged for several days on two occasions.
