Over the past decade, in-situ stabilisation with PolyCom has become a popular method of unsealed road pavement rehabilitation.
In-situ stabilisation is a road maintenance technique adopted to maintain the dry strength of poor quality materials, extending the life of unsealed road pavements. It is often more economical to recycle and improve the quality of in-situ materials within an existing pavement rather than excavating to spoil and importing better quality virgin material, especially where haulage distances are uneconomical.
The trend to use PolyCom Stabilising Aid on unsealed roads continues strongly for Australian road authorities. Used in failed patch repairs, haul roads and highways, PolyCom improves the workability and strength of in-situ materials in rutted and deformed pavements without the need for a re-sheet.
Life-cycle results indicate that unsealed pavements treated with PolyCom reduce water usage, greenhouse gas emissions and cost by 70-90%.
Many councils are foregoing 'dust suppression' practises to address the cause rather than the symptom, improving the quality of the in-situ materials with PolyCom to reduce material loss.
For sealed roads where sections have failed, the application of PolyCom enables existing poor quality materials to be stabilised to produce a pavement of improved strength and quality before re-sealing.
One of the most effective road recycling processes in Australia, in-situ stabilisation with PolyCom Stabilising Aid enables engineers, asset managers and works officers to address tight road funding budgets by building stronger roads that go the distance with the materials already at hand.
