... 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.
