Project date:
March - April 2017

Client:
QTMR

Details:

RPQ were contracted to reseal the main road of Stradbroke Island from Dunwich to Point Lookout. RPQ had to design and construct a 14/7mm Double/Double PMB reseal on the main alignment with an additional trial of Triple/Triple seal designs in areas of high stress such as intersections and road curves.   RPQ Engineers and Supervisors worked closely with QTMR, RoadTek, local residents and the Quandamooka Aboriginal people to deliver a high quality product and personalised service.  As RPQ have undertaken local council reseal and construction programs on various islands throughout the years, we have proven experience that helped the team to overcome the logistical and unpredictable weather challenges the islands can possess.  This previous experience, coupled with RPQ’s extensive knowledge base and the use of technical and historical data contributed to the successful completion of the project.

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.

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. 
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.
