Prior to works the materials were analysed using Austroads Perforamnce Based Analysis to confirm the issues and make the most appropriate reccommendation for product application options.

Polychlor Omega was chosen as the most appropriate treatment option considering the low shrinkage and plasticity of the road base.

Surface application was chosen as the most appropriate treatment option. Surface application is a means of keeping the dosage rate down to reduce costs. Surface treatment keeps the adhesive treatment in the material that has to be protected the most, the roadsurface.

Three different dosage rates were trialed and the treated areas are now being monitored by Council to determine the most appropriate dosage rate for future applications.

The pavement wear tester during a test

The machine operates on the principal of a constant force pushing a standard compaction cylinder against a wire brush that rotates at constant speed. The time to wear the cylinder down is recorded and also the cylinder change in length is recorded to give a wear resistance score (WRS).

The wear tester has shown that the wear resistance of gravels for unsealed roads can be increased significantly with treatment using Polychlor or Polytahr.

Following is an example of the increase in wear resistance after treatment

Treatment: Polytahr

Material: Sandstone gravel

Control WRS: 118

Treated WRS: 195

Yorke Peninsula Council (YPC) in South Australia has utilised Polychlor since 2021 to reduce dust on unsealed local roads in areas near residents. YPC has extensive experience in the application of Polychlor in various scenarios. The Polychlor treatment has significantly reduced complaints from residents, while also reducing road maintenance needs. Polychlor provides strong adhesion of soil particles in materials with a PI of 0 to 20, this characteristic holds the road surface together and reduces dust and gravel loss.

The remote beauty of the Abrolhos Islands

The logistical challenges of the Abrolhos Islands made Polychlor the obvious choice of stabilisation method. The quantity of product to carry out the works is minimal, also the equipment to blend and apply the product is lightweight and easy to transport to the site.

Polychlor is also very safe for personnel and the environment, making it an ideal choice for this project.

The Abrolhos Lobster fishery is Australia's most valuable single species wild capture fishery and has a longstanding commercial and economic history at the Abrolhos Islands.

The testing procedure and soil analysis is sumarised in the video above.

The tested showed that the performance of the yellow sand was greatly improved with the addition of Polychlor. The soil characterisitis of the yellow sand are as follows;

PI = 6

Linear shrinkage = 4

Using the South African Performance Based Modeo for unsealed pavements the material is classified as erodible.

Pindan soils are fine-grained red soils with low plasticity and little natural cohesion found throughout Northern Western Australia. The Pindan soil detailed in this testing was sampled from the 30 Mile Tank on Cape Leveque Road, North of Broome WA. The testing included particle size distribution, Atterberg limits, linear shrinkage, RMS T133 Durability of Road Materials and CBR.

The soil was found to have the following characteristics;

Liquid Limit = 21

Plastic Limit = 14

PI = 7

Shrinkage = 4%

The particle size distribution and linear shrinkage are used for analysis with the South African performance based model. This analysis showed that the Pindan soil is prone to erosion, corrugating and raveling.

The RMS T133 test is used to evaluate the improvement in performance provided by stabilisation. The test requires formation of 1 litre soil cylinders using standard compaction. After curing the cylinders, they are placed into a water bath for 5 hours, dried, then wire brushed to remove loose material and weighed. This process is repeated 12 times.

For the T133 test the untreated control cylinder lost 95% of its original mass after 1 cycle of soaking, the remaining material was too fragile to carry on with the test. The Polychlor treated cylinders showed good resistance to water erosion, after 12 cycles of soaking, drying and wire brushing the specimens only lost 3% to 4.5% of their original mass.

The pavement of the Coral Bay aerodrome is composed of fine non-plastic gravels which has resulted in unraveling due to aircraft traffic. The aerodrome is approximately 1100km North of Perth and is used for general aviation and by the Royal Flying Doctor Service. Several options were considered for the improvement of the runway including resheeting the runway with new gravels, due to the significant costs of long haul distances to bring in it was decided to treat the existing pavement using Polychlor Omega pavement stabiliser.

The aerodrome pavement Polychlor stabilisation project provided some unique circumstances;

Being located on a salt pan with a shallow water table, leaving the pavement constantly in a damp state
The water being available for the pavement works was a strong salt brine with a salt content of 4% w/w
Low to zero PI gravels with high CBR

Blending Polychlor into the water tankers. The water used is salt brine from a soak pond in the salt pan to the East of the aerodrome runway. The salt content of the brine was measured to be 4% w/w

The Polychlor solution was applied to the pavment material by incorporation using a pavement stabiliser mixer. After stabilising the pavement was rolled with a steel drum roller and eventually finished using a multityre roller. The benefits of stabilising this fine grained pavement using Polychlor Omega is in providing enhanced cohesion to prevent pavemnt loss and loose material on the runway. This helps to prevent aircraft damage.

The soil used in this series of tests is sandy silty clay sub soil gathered from various sub-division sites around Adelaide. The testing was carried out by SMS Geotechnical in Adelaide. This testing is part of our ARRB TIPES product assessment. It was found that Polychlor incresed the CBR in this material from 4.5 to 11.

RMS test method T133 (modified) was also carried out with a 5 hour soaking period showing that the material loss due to inundation was reduced from 77% to 17%.

Increasing the CBR from 4 to 11 is a significant result for sub-grade materials. The CBR increase will allow for more durable pavements or reduction in pavement thickness.

The soil PI was 27 and the grading is very fine. The T133 test showed that Polychlor is able to make significant reductions in material loss due to erosion and scouring. The testing has shown that Polychlor is able to be utilised in a wide range of soils.

Stabilisation of shoulders on sealed roads has been the main application of Polychlor at Ipswich City Council. Significant savings have been made in stabilising shoulders to protect the pavement from scouring and erosion during wet weather. The pavement material used on the shoulders is from Russells Quarry at Pine Mountain QLD. This material performs very well in unsealed road applications, and it's performance is even further enhanced with application of Polychlor. Application of Polychlor has been by full depth stabilisation of the pavement, and also surface treatment.

Testing was carried out to get a comprehensive understanding of the benefit that Polychlor provides to pavement performance. PSD analysis showed that the Russell's material has 11-16% passing the 0.425mm sieve and a linear shrinkage of 9%. Remoulded specimens were also made and subjected to RMS T133 Pavement durability testing. The image shown is after drying of specimens subjected to 5 hours of soaking. The loss of material after 5 hours of soaking is reduced by Polychlor treatment from 57% loss to 17% loss. A clear demonstration that application of Polychlor significantly reduces pavement damage during rainfall events.

The Southern Mallee District Council has a significant quantity of rural roads composed of clayey loam. Maintenance for these roads is a challenge due to the remote locations of the roads and long haul distances for water. Polychlor is one of the options which has been utilised to reduce maintenance frequency and limit damage to the road network during periods of precipitation.

The other reasoning behind the application of Polychlor is to enable use of low cost clayey loam for pavement materials rather than trucking in crushed rock from distant quarries.

Polychlor is able to provide significant increases in the CBR of a wide range of materials, greatly reducing damage to unsealed pavement during times of wet weather and high traffic.

Bundaberg Regional Council stabilisation and dust suppression works

Recent works around Bunderberg Regional Council have utilised both Polytahr stabiliser and Polychlor Omega. Polytahr was used to stabilise unsealed pavements to a depth of 100mm, after allowing the pavement to dry out this was followed by application of a film of Polychlor Omega to act as a surface stabiliser and dust suppressant.

Polychlor Omega is applied using a water tanker. It is odorless and has a low viscosity so it doesn't cause any issues with tankers. It is easy to spray out and maintain full coverage of the surface due to it's low viscosity behavior.

The Polychlor Omega is applied 3 to 5 days after completion of the stabilisation works. This ensures the pavement is dry immediately prior to application, so the solution soaks into the surface within minutes. Due to its adhesive properties Polychlor Omega will stabilise the surface and protect it from traffic wear and weather erosion.

Polychlor Omega protects and stabilises the surface due to its adhesive properties. Dust is also eliminated or significantly reduced. Due to its economical nature,Polychlor Omega is useful in situations where there are significant dust emissions caused by harvest related heavy vehicle traffic. Our blending equipment is easy to use and comes with all the necessary standard operating procedures, enabling your staff to batch Polychlor Omega solution effectively and safely.

Polychlor Omega can also be used for full thickness stabilisation of pavements.
