Build a road using recycled materials from construction waste on national road 3 (Rn3) in the governorate of Ben Arous. This is the objective of the RE-MED pilot project officially launched during workshops in Gammarth on the theme: “Tunisia the path towards a sustainable circular economy for an accelerated ecological transition
The section of road, which will be built as part of the RE-MED project co-financed by the European Union, is 1.2 kilometers long and consists of 4 sections: 3 sections which will be used to test the integration of one or several recycled materials, and a fourth which will be a reference section built with natural and non-renewable materials.
This road will be equipped with sensors to monitor its evolution in real time under the effect of traffic and changing climatic conditions. The objective is to evaluate the new road structures and analyze the impact of climatic variations, we read in a note from the Tap agency.
Adapting roads to climate change
The objectives of this project, presented by RE-MED coordinator Oumaya Marzouk, demonstrate the interest in recycling construction and demolition materials in a context of tension on the aggregates market, to create local jobs, reduce risks health and flooding linked to the proliferation of landfills for construction materials and public works, to reduce land pressure and the carbon footprint and to adapt roads to climate change.
Speaking at the workshop, the Minister of Equipment and Housing, Sarra Zaafrani, declared that “the creation of a test bench on national road no. 3 is a pilot experiment aimed at validating a new product and a new process . “The correct monitoring and optimal management of data received from the monitoring system, used for the first time in Tunisia in the road construction sector, will make it possible to compare the behavior of pavements made with natural raw materials and those made with natural materials. recycled, and to evaluate the technical efficiency of the use of demolition and construction waste ,” explains the minister. And added: “In addition to technical validation, a regulatory, legal and regulatory basis is recommended to ensure the introduction of demolition and construction waste into the road construction market in Tunisia and to provide the various stakeholders with the necessary guarantees.”
“The management of demolition and construction waste represents a major challenge, given the limited resources of raw materials and the positive impact on the environment and public health,” insists Ms. Zaafrani.
Circular economy for sustainable construction
The Minister of the Environment, Leila Chikhaoui, stressed, for her part, that the recovery of demolition and construction waste constitutes an important part of the national circular waste management strategy adopted as part of the National Transition Strategy ecological approved last February.
Ms. Chikhaoui believes that the recovery of construction waste would contribute to resolving ecological (liberation of the space occupied by this waste), economic (introduction of new resources into the market for the construction of infrastructure and urban furniture) and social problems. (creation of businesses and jobs).
The RE-MED project ( “Application of innovation to the development of the circular economy for sustainable construction in the Mediterranean” ) is a partnership between 4 Mediterranean countries (France, Italy, Lebanon and Tunisia) to promote the use of circular economy in construction. and the demolition waste sector.
