State Invests in Concrete for Highways, Investing Over R$ 150 Million in PRC-280. The Project Uses Whitetopping Technique for Greater Durability, Safety, and Resistance to Heavy Traffic.
Paraná’s highways are undergoing a surprising transformation! An investment of over R$ 150 million marks the beginning of a new era on the state’s roads, now utilizing concrete.
This material, widely used in the United States, brings an ambitious promise: to last twice as long as traditional asphalt.
The Paraná government opted for an innovative and durable approach, betting on a more expensive but more resistant paving technique to withstand the wear caused by heavy traffic and enhance safety on the roads.

According to the Paraná Department of Highways (DER/PR), this change on PRC-280 not only represents an evolution in local infrastructure but can also serve as an example for all of Brazil.
Concrete on PRC-280: Multi-Million Project Advances Rapidly
The PRC-280 highway, between Palmas and Clevelândia in southwestern Paraná, is one of the first in Brazil to adopt concrete as the primary paving material, with a project valued at approximately R$ 157.8 million.
According to DER/PR, responsible for oversight, the project reached 83.81% completion in October and is nearing completion, expected by the end of this month.
The technique used is whitetopping, which involves utilizing the old asphalt as a base for the new Portland concrete, ensuring a stronger bond and a reinforced structure to support heavy loads.
This project encompasses 45 kilometers of highway, including third lanes and shoulders, significantly enhancing safety and capacity on the road.
Per the plan, after the paving is completed, complementary services such as drainage, signaling, and grass planting will be carried out, expected to finish in the first quarter of the following year.
Works and Safety: How Concrete Changes the Road Scenario
The works on PRC-280 stand out not only for the use of concrete but also for the improvement in safety devices.
The project includes the installation of triangular concrete curb for efficient drainage, along with new signs, reflective studs, and metal barriers.
To ensure traffic flow, DER implemented a “stop-and-go” system, allowing the highway to operate 24 hours a day, even with a reduced lane.
This change could prove revolutionary: concrete is not only more resistant and cost-effective in the long run, but it is also safer against skidding and has better rainwater drainage, an advantage in areas with heavy rainfall.
Expansion to Mariópolis: New Phase in 2024
PRC-280 is preparing for a new phase, expanding the concrete restoration to the stretch between Clevelândia and Pato Branco, totaling 37.94 kilometers.
This time, the investment will be R$ 180.9 million, with concreting expected to begin in January.
As the first step, the shoulders in the Mariópolis area are already being recycled in preparation for the installation of the rigid pavement.
According to DER/PR, this will be the third whitetopping project in the region, reinforcing the strategy to use concrete in areas of heavy truck traffic, a frequent reality on PRC-280, which connects the Southwest to Southern Paraná.
This choice aligns with a trend observed internationally, where concrete is preferred on highways experiencing heavy freight vehicle traffic, as the material withstands wear and deformation better.
Why Concrete Could Be the Future of Highways?
The adoption of concrete represents a significant advancement in Brazilian road infrastructure.
This material, in addition to being more durable, offers a lifespan of about 20 years – double that of common asphalt – and requires less maintenance, reducing costs for the state and taxpayers.
In countries like the United States, concrete is widely used on high-traffic roads due to its resistance, safety, and long-term economy.
With this change, Paraná positions itself as a pioneer in Brazil by bringing this technology to its highways, potentially encouraging other regions to invest in more durable and sustainable solutions for their roads.
The Impact on the Future of Brazilian Highways
The investments made by the Paraná government are a clear sign that highways can be modernized and adapted to international standards of durability and safety.
PRC-280 thus becomes a laboratory for Brazil, where authorities can observe the results and assess the feasibility of expanding the use of concrete to other highways, particularly in high traffic areas.
The rapid advancement of the works and the success of the execution thus far demonstrate that this bet can bring long-term benefits, ensuring safer and better-maintained roads for drivers and transporters.
The question remains whether other states will follow Paraná’s example and adopt this solution that promises to change the face of Brazilian highways.
And you, do you believe that concrete could really be the future of Brazilian highways?
Que genial! Já era tempo ! Mas, uma boa supervisão econômica, também cairia ben!
