Pierre-Marie-Jérôme Trésaguet is sometimes considered the first person to bring post-Roman science to road building. A Frenchman from an engineering family, he worked paving roads in Paris from 1757 to 1764.

As chief engineer of road construction of Limoges, he had opportunity to develop a better and cheaper method of road construction. Trésaguet had recommended a roadway consisting of three layers of stones laid on a crowned subgrade with side ditches for drainage. Thomas Telford, born in Dumfriesshire Scotland, was a surveyor and engineer who applied Tresaguet’s road building theories. In 1801 Telford worked for the British Commission of Highlands Roads and Bridges. He turned the other faces more vertically than Tresaguet’s method.

The longest edge was arranged crossways to the traffic direction, and the joints were broken in the method of conventional brickwork, but with the smallest faces of the pitcher forming the upper and lower surfaces. Broken stone was wedged into the spaces between the tapered perpendicular faces to provide the layer with good lateral control. Telford kept the natural formation level and used masons to camber the upper surface of the blocks. To finish the road surface he covered the stones with a mixture of gravel and broken stone. Where the structure could not be raised, Telford drained the area surrounding the roadside. Previous road builders in Britain ignored drainage problems and Telford’s rediscovery of these principles was a major contribution to road construction. In 1787, he became a trustee of the Ayrshire Turnpike in the Scottish Lowlands and during the next seven years this hobby became an obsession.

He moved to Bristol, England, in 1802 and became a Commissioner for Paving in 1806. Cambering and elevation of the road above the water table enabled rain water to run off into ditches on either side. A workman could check the stone size himself by seeing if the stone would fit into his mouth. He also wrote that the quality of the road would depend on how carefully the stones were spread on the surface over a sizeable space, one shovelful at a time. Neither was anything to be laid on the clean stone to bind the road. The action of the road traffic would cause the broken stone to combine with its own angles, merging into a level, solid surface that would withstand weather or traffic. Keeping the surface stones smaller than the tyre width made a good running surface for traffic.
