Driving more sustainable pavement solutions

On the Eresma Expressway (A-601) in Segovia, we used recycled material from the road surface that we removed to renew the wearing course. The project incorporates 30% milled material.

Sacyr Concesiones is putting circular pavement maintenance to the test on the Autovía del Eresma (A-601). Along a one-kilometer stretch, the concessionaire has reused milled asphalt from the existing roadway as feedstock for a new surface course.

The paving works incorporate 30% reclaimed asphalt pavement (RAP) from the highway’s aged wearing course into the new bituminous mix—double the 15% currently recommended by regulations for this type of layer.

A field test with long-term potential

The pilot section, located between kilometer markers 81 and 82 in direction to Segovia, is designed to prove that today’s recycled asphalt technology can increase RAP content in surface mixes without compromising ride quality, durability or overall pavement performance.

“On this pilot section, we are cutting the amount of virgin aggregate needed in the mix,” said Miguel Ángel Moreno, from Sacyr Concesiones’ Pavements Department. “We also reduce material sent to landfill and lower the carbon footprint associated with asphalt production,” he added.

The trial will allow the team to track the mix in service, monitor its long-term behavior and assess whether the approach can be scaled to future maintenance campaigns.

“We want to see how this mix holds up in the field and whether the solution is sustainable, technically viable and cost-effective over time,” said Ángel Delgado, manager of the Autovía del Eresma.

 

 

 

Technology and collaboration drive the pavement trial

The recycled asphalt mix—a BBTM 11B gap-graded surface mix with 30% RAP—was manufactured at Padecasa’s plant in Aldeavieja, Ávila.

The project brings together the Regional Government of Castile and León, Sacyr’s Pavements Department, Sacyr Concesiones’ Innovation team and Padecasa. It builds on a 2024 test section that used 15% RAP, the maximum share currently recommended for this type of wearing course.

The initiative supports circular economy targets and aligns with Castile and León’s regulatory framework, which requires at least 3% of aggregates used in pavement rehabilitation works to come from recycled materials.

With pilots like this, Sacyr continues to test lower-impact road maintenance solutions that conserve natural resources, reduce waste and support more sustainable infrastructure management.
 

Innovation beneath the surface at Binningup

An innovative repair was carried out on the transition chamber at our desalination plant in Perth, Australia, which not only maintained the integrity of the seawater intake system but also ensured that the marine environment was protected at all times.

At the Southern Seawater Desalination Plant in Binningup, Western Australia, critical offshore infrastructure plays a key role in ensuring a reliable supply of drinking water for the region, while supporting the protection of the surrounding marine environment.

One key component of the seawater intake system is the Stage 1 Transition Box, a buried concrete structure that connects two 1.6 m HDPE intake pipelines to the plant’s intake tunnel. Operating beneath the seabed in a challenging marine environment, this structure plays an important role in maintaining the integrity and reliability of the plant’s seawater intake system.

Following the identification of progressive structural degradation and sand ingress, Sacyr Agua worked closely with Water Corporation and specialist delivery partners to develop a low-impact remediation solution. The objective was clear: restore functionality and extend asset life without requiring full replacement of the structure.

 

 

Developed in collaboration with SEA Global, SF Design and Fremantle Commercial Diving, the solution involved the installation of a precision-machined modular HDPE lining system. Reinforced in key locations and grouted in place, it created a sealed, load-bearing internal flow path. Computational Fluid Dynamics (CFD) modelling, structural verification and full-scale dry and wet testing were used to validate the design ahead of offshore installation.

The project was delivered under demanding offshore conditions, including subsea construction, restricted access, limited weather windows and stringent environmental controls. Specialist diving teams installed more than 75 custom-machined HDPE components within the existing structure, restoring intake integrity while minimising disturbance to the surrounding marine environment.

“This was more than a repair – it was a coordinated effort across design, fabrication and marine execution,” said Paul Oosthuizen, Maintenance Manager at the Southern Seawater Alliance.

 

 

By rehabilitating the existing structure rather than replacing it, the project reduced seabed disturbance, minimised operational impacts and extended the service life of a critical element within the plant’s intake infrastructure.

In 2025, the Transition Box Remediation project received industry recognition through an Australian water sector award for innovation in marine infrastructure delivery.

Discover the species found around our projects

Our activities are carried out in natural environments where biodiversity plays a crucial role. Therefore, we are committed to protecting and preserving the ecosystems and communities with which we coexist.

We work in natural environments where biodiversity plays a vital role. That is why we are committed to protecting and preserving the ecosystems and communities around them.

Caring for nature is not only about taking protective measures; it also means observing it, understanding it and appreciating its richness.

Colombia offers a good example. There, our colleagues Andrés Mauricio Forero Cano, a biologist in the Environmental Area of the Buenaventura-Loboguerrero-Buga project, and Manuel Alejandro Posso Gaviria, Environmental Birds' Route Project Coordinator at Unión Vial Camino del Pacífico who captured a series of images showcasing the fauna and flora found in the area. The photos were part of our RevelaVerde competition.

Andres Mauricio's photographs were taken in the Venado Verde Nature Reserve, in the area surrounding this road project.

“With these photographs, I want to show the immense biodiversity found in our region, particularly among amphibians and reptiles, a group that is still little known and often undervalued,” says our colleague.

“The photographs were taken using macro photography techniques. I used a Nikon D7200 camera with a 60 mm Laowa macro lens, external flashes and diffusers,” explains Andrés Mauricio.

Captured while work was underway, these five photographs bring us closer to a fascinating world of colors, shapes and behaviors that often goes unnoticed, yet plays an essential role in the balance of ecosystems.

The five photographs show:

1.    Pacific lemur frog (Agalychnis psilopygion). “It is a species of incredible beauty and fragility that lives only in well-preserved forests.” 

 

 

2.    Cane toad (Rhinella horribilis). “This species has long been overlooked because of its appearance, but it plays a fundamental role in our ecosystems by controlling insect populations. Through macro photography, I wanted to capture its splendor and show that the world should look beyond appearances and recognize what lies beneath.” 

 

 

3.    Dwarf spiny iguana (Enyalioides heterolepis). “This lizard lives in the leaf litter of pristine forests and has a variety of scales that give it a striking appearance, which I wanted to highlight through macro photography.” The image won first prize in the Flora and Fauna category. 

 

 

4.    Glass frog tadpoles (Teratohyla spinosa). “These small glass frogs live in the vegetation that grows along streams. They lay their eggs in gelatinous clusters on leaves. When the eggs hatch, the tadpoles develop inside this gelatinous mass until they are large enough to drop into the streams and complete their development.” 

 

 

5.    Broad-headed anole (Anolis latifrons). “This photograph was taken with a wide-angle macro lens, combining the detail of macro photography with part of the animal’s surroundings. This lizard species lives in vegetation near streams. In the photograph, I wanted to capture both its remarkable details and the habitat where it is usually found.” (top photo)

These images remind us how important it is to coexist responsibly with local wildlife and to make nature protection part of how we deliver our projects. Learning about the species that live in the areas where we work is the first step toward helping conserve them.

Another colleague who participated in RevelaVerde with his photographs is Manuel Alejandro Posso Gaviria, Environmental Birds' Route Project Coordinator at Unión Vial Camino del Pacífico.

We rescued a turtle at our Skikda desalination plant


Our commitment to biodiversity is reflected in practical action, showing the responsibility and care our teams bring to the ecosystems around us.
A recent example took place at the Skikda Desalination Plant O&M Joint Venture in Algeria, where the plant team stepped in to rescue a sea turtle that had become trapped on the premises. Thanks to the team’s swift response, the animal was safely released and returned to the sea in good condition.

Zenina Hadjer, a laboratory technician and the author of the images submitted to the RevelaVerde competition, explains: “During operations at the plant, a sea turtle was found trapped in the facility’s intake basin. Aware of our responsibility to the ecosystem, our team acted immediately. We carefully rescued the animal and took it to Srigina Island, where it was safely released back into its natural habitat.”
 

 

“These images show how our industrial operations can coexist with the preservation of local biodiversity,” says our colleague.
Actions like this show that sustainability is also shaped by everyday decisions and efforts.

Thanks to our teams’ commitment and dedication, we help protect biodiversity and preserve the natural value of the environments where we operate.
