Eco-friendly asphalt remix

In today’s road construction scene, the heat restoration remix is in the spotlight for a variety of reasons, especially as its eco-friendly image in Nordic countries faces challenges. Recent concerns suggest that environmentally speaking, traditional milling and new coating methods might gain an edge over heat restoration, particularly from an Environmental Product Declaration (EPD) standpoint. However, in the unique context of Estonia – where road construction funds are limited and raw materials are mostly shipped in – heat restoration still holds relevance. The significant transport component of raw materials in Estonia may result in higher calculated CO2 emissions compared to Nordic countries, making heat restoration a cost-effective choice.

The essence of the hot resurfacing remix lies in its minimal use of a new asphalt mixture. It primarily revolves around heating up the old pavement, removing it, and reassembling it on-site with a minimal addition of new asphalt. Typically, only 20-30 kg/m² of new asphalt mixture is used, about five times less than conventional asphalt laying. To revitalize the old asphalt, chemicals can be added, extending its useful life. This not only makes hot restoration economically friendly but also ensures pavement quality comparable to fresh asphalt pavement. The economic advantage, coupled with faster repairs, enhances road safety and overall traffic flow.

Considering the waning popularity of heat recovery technology in Nordic countries due to CO2 emissions, Estonian public procurements might witness intense competition among Nordic remix technology providers. This competition could potentially drive down unit prices in public procurements, making road renovation more cost-effective. The use of Nordic equipment in Estonian remix procurements, owing to a modest state order, means more road surface renewal with fewer financial resources. A robust road network, achieved economically, has the potential to spur economic recovery and open up new opportunities.

In conclusion, heat recovery remix technology can offer a valuable contribution to Estonia’s road infrastructure. The National Audit Office’s 2022 audit highlighted the challenge of meeting even minimal goals for state road maintenance with decreasing funding, impacting the state’s economy and road user safety. Faced with reduced funding for Estonian roads in the coming years, the remix method emerges as a viable alternative. It not only sustains the sector with smaller funds but also maintains roads in better condition, offering a practical solution to prevent the degradation of the road network due to underfunding.

The article explores the relevance of heat restoration remix technology in Estonian road construction amid challenges from Nordic countries. Despite concerns over environmental impact, the economic advantages, coupled with potential competition from Nordic providers, position the remix method as a cost-effective solution for maintaining road infrastructure in Estonia. So, what should we do?!

  1. Foster research collaboration with Nordic providers to leverage their expertise and equipment for cost-effective road renovations
  2. Conduct a comprehensive environmental assessment to understand the true ecological impact of heat restoration remix technology in the Estonian context
  3. Invest in the development of local machinery for heat restoration remix to reduce dependence on Nordic equipment and stimulate the economy
  4. Launch a public awareness campaign to educate citizens about the economic and environmental benefits of the remix method to garner support
  5. Review and adjust government policies to prioritize road infrastructure development, ensuring sustained funding and support for innovative technologies
  6. Implement industry-wide training programs for local professionals to enhance their skills in heat restoration remix technology, promoting self-sufficiency and job creation in the sector
