About Pierre-Marie-Jérôme Trésaguet
- Pierre-Marie-Jérôme Trésaguet (15 January 1716 – 1796) was a French engineer.
- He is widely credited with establishing the first scientific approach to road building about the year 1764.
- Among his innovations was the use of a base layer of large stone covered with a thin layer of smaller stone.
- The advantage of this two-layer configuration was that when rammed or rolled by traffic the stones jammed into one another forming a strong wear resistant surface which offered less obstruction to traffic. Trésaguet was born in Nevers, the youngest son from a family of engineers.
- He began his career as a sub inspector in the Corps des Ponts et Chaussées (Bridges and Highways Corps), in Paris.
- He later moved to Limoges, Haute-Vienne as chief engineer in 1764.
- In 1775 he was appointed inspector general of roads and bridges for all of France.
- He published a paper describing his road building methods.
