SPA pursues pavement rehabilitation and construction methods that involve utilisation and re-engineering of existing materials onsite foremost, with almost all existing pavement materials possessing a potential asset value regardless of the current quality and including contaminated materials. Reusing existing pavement materials may reduce the lifecycle impact of those materials if they were alternatively discarded and replaced with new and imported road materials. By recycling the existing pavement materials, insitu stabilisation techniques can provide advantages over replacements options including:- Prevention of excavation of the existing materials
- Reduction of trucking materials to and from site
- Preventing the disposal of excavated materials which still have an asset value
- Limiting the quarrying of replacement materials
- Potential to significantly reduce energy usage and greenhouse gas emissions by reducing the above mentioned activities |

Vibration |
SPA is able to undertake pavement works using plant with oscillating features, rather than standard vibration in addition to static rolling with heavier plant, which has the potential to drastically reduce vibration impacts resulting from construction activities on site. |

Contamination and
remediation |
Using geotechnical engineering and stabilisation to modify and improve pavement materials, SPA can undertake pavement rehabilitation and remediation of various contaminated materials pending assessment of a suitable treatment. This can prevent excavating and disturbing contaminated materials initially, managing the disposal location of the contaminated materials, and provides a safer final-product due to the contaminated materials being modified. |

Diversion from landfill |
Pavement and construction and demolition materials that could otherwise be discarded can be diverted from landfill or alternative stockpile arrangements by approximately up to and over 70%. Materials may remain on site and become part of the new road asset, simply through recycling and re-engineering up to 100% of the existing road materials. Stabilising pavements insitu prevents the generation of construction and demolition waste in the first place, such as, the worldwide waste-product RAP can be limited initially if recycled into existing pavements using stabilisation foremost. |
