One innovative and sustainable technology has helped recover the asphalt along the Rodovia dos Imigrantes Highway in Mato Grosso. The solution, called "rubber asphalt," was adopted by the Odebrecht Highways company Rota do Oeste and offers two main benefits: it makes the pavement more resistant than the conventional one and helps protects the environment, since it uses tires that would be discarded.
The lining is made from tire rubber dust added to asphalt mix. The material's elasticity allows for improved sealing, which reduces water infiltrations and prevents the formation of fissures and cracks. The result is more durable pavement. "Furthermore, the tires represent 63% of the waste picked up by the concessionaire," revealed Pedro Ely, responsible for Sustainability at Rota do Oeste. "The solution reinforces our commitment to the environment and the safety and quality of the highways we operate," he said.
Double Surface Treatment (DST) with Petroleum Asphalt Cement (PAC), which forms rubber asphalt, is being used for the first time in the state. The recovery work is being completed only during the daytime and mobilizes 30 people and seven machines.
