Respect. (from the lat. respectu) n. 1. respect; 2. consideration; high regard; 3. deference; compliance; veneration; 4. honour; worship; 5. relation; refererence...
We believe that everyone should be respected for their work, for their attitudes, opinions and options.
Rigor. (from the lat. rigore) n. 1. harshness; strength; 2.fig., severity; punctuality; accuracy.
There is no "more or less levelled", "more or less upright”, "more or less clean" or "more or less safe", but rather “levelled”, "upright”, "clean” and “safe". The rigour is reflected in our procedures, in time and in the rules to follow. In the light of moral and principles, being severe means being rigorous.
Passion. (from the lat. passione) n. 1. intense and usually violent feeling (affection, joy, hate, etc.) which hinders the exercise of impartial logic; 2. derived from a feeling; 3. great predilection; 4. partiality; 5. great grief; immense suffering...
Under the sign of passion – a text of the Portuguese poet Regina Guimarães – is our icon. Passion is to reveal great enthusiasm for something, favourable encouragement or opposite to something.
It is the sensibility transmitted by an architect or engineer through work.
Passion is the dedication to a project. Passion is a state of warm soul.
Loyalty. (from the lat. legalitate) n. the quality of being loyal; fidelity; sincerity.
Respect for the principles and rules that guide the honour and probity. Faithfulness to commitments and agreements undertaken, staunch character.
To remain loyal to the business partners because we depend on them and they depend on us.
Being trustworthy for being loyal.
Solidarity. (from the lat. solidare) n. 1. the quality of being solidary; 2. reciprocal responsibility among the members of a group, namely social, professional, etc.; 3. sense of sharing another’s suffering.
Being solidary is being a friend, offering our hand with genuine generosity and bringing joy and human warmth to those who, somehow, are marginalized. Being solidary is being more human. A solidary company is recognized as a fair and non-selfish company. A solidary company is a preferred choice in business. It is a more competitive company. Volunteering is a vehicle to solidarity. It is modern, fair, cultured, friend, it is a noble gesture of moral elevation.
Courage. (from the lat. coraticum) n. 1. bravery facing danger; intrepidity; to have audacity; 2. moral force before a suffering or setback; 3. [fig.] to input energy when performing a difficult task; perseverance...
Courage is essential in our life. Courage to face less pleasant situations when complex issues come up, not expecting random resolutions.
It is a value that we must highlight as opposed to the fearful, cowardly and laziness.
The courage to react to criticism not with an attitude of demotivation or sadness, but rather to search for the means and the action to overcome its own reason. This kind of courage, which is also an intellectual courage, is highly recommended.
Ambition. (from the lat. ambitione) n. 1. vehement desire of wealth, honours or glories; 2. expectation about the future; aspiration; 3. lust; greed…
Vehement desire to achieve a particular goal. Ambition not to resign ourselves. Ambition to take the best potential from ourselves. Ambition to deserve ourselves. Ambition to be athletes in our top-level competitive jobs. Ambition to beat our brands. Ambition to get the best deals with the maximum value, due to the high levels of proficiency and efficiency.
Esthetics. ESTHETICS (from the Greek aisthetiké, "sensitive") n.f. 1. Philosophy branch of philosophy that studies the beauty and nature of artistic phenomena; 2. author's own style, time, etc.; 3. harmony of shapes and colors, beauty; 4. set of techniques and treatments that aim to beautify the body.
We decided to build the company's economic foundations under a cultured, cosmopolitan and cool image. Because it is a charming state of being. Good taste because we are sustainable and we respect the planet. Good taste because we are sensitive. Good taste just because.
Responsibility. (from the lat respondere) n. the trait of being answerable to someone for something or being responsible for one's conduct; a form of trustworthiness.
We must be certain that, before a choice, we chose what is best for both of us and not just the best for each one. Each employee is responsible for his negotiated activity and co-responsible if the co-worker does not fulfil his own task, thus preventing the common goal. A team is a set of individuals - is a whole. In the business game, as in social or family contexts, everyone must comply with their own relative position and we shall not permit that one of ours fails to be in our team.

As part of the project carried out by dst and the University of Minho, new formulations were developed for two types of mix, both incorporating 50% milled material
dst and the University of Minho have developed a solution that allows up to 50% of the pavement removed from deteriorated roads to be recycled, transforming it into raw material for new pavements with the same technical performance, placing Portugal alongside countries such as Germany, France, Spain, and the Netherlands. The company now aims to position Portugal as an exporter of this technology, whether to European markets, Portuguese-speaking countries, or emerging markets.
The solution represents a decisive step forward in the rehabilitation of the national road network, which consists mainly of flexible pavements, many of which are nearing the end of their useful life, and paves the way for a more circular, efficient, and decarbonized construction model.
Milled material that was previously discarded becomes a raw material, reducing dependence on aggregates and bituminous binders with high environmental impact, optimizing production costs, and increasing the efficiency of construction processes.
“In addition to laboratory validation, we were able to confirm its applicability in an industrial setting, including manufacturing, application, and compaction, which represents a significant advance for the road sector. This is a concrete contribution to the sector’s decarbonization, while simultaneously promoting resource efficiency, technological innovation, and alignment with international best practices,” says Mafalda Rodrigues, the project lead.
As part of this project, new formulations were developed for two types of mix: AC14, intended for wearing courses, and AC20, applied to binder and base courses—both incorporating 50% milled material.
This is a significant technical achievement, as current practice in Portugal ranges from 10% to 30% incorporation and remains limited to a small number of projects, due to reservations on the part of project owners and designers regarding these solutions.
To support this new generation of sustainable solutions, dst operates a recycling plant dedicated to processing recovered asphalt mixtures and an asphalt mixing plant equipped to incorporate up to 50% recycled material. This infrastructure ensures total control of the process, from recycling to on-site application, and clearly distinguishes dst within the national context.
The entire solution underwent rigorous laboratory and field testing to ensure mechanical and functional performance levels equivalent to those of conventional mixtures.
The conditions for production, on-site application, and compaction were also studied and validated, ensuring the solution’s feasibility in real-world production and use starting in 2026.
In addition to hot mixes, WMA (Warm Mix Asphalt) technology was also developed, which allows for lower production and application temperatures, directly reducing energy consumption and greenhouse gas emissions—that is, a dual benefit: environmental and operational.
