The first indications of constructed roadways date from about 4000 BC and consist of stone paved streets.
The builders of the late 1800s depended solely on stone, gravel and sand for construction. Water would be used as a binder to give some unity to the surface.
John Metcalfe, a Scot born in 1717, built about 180 miles of roadways in Yorkshire, England (even though he was blind). He built it with three layers: large stones; excavated material; and a layer of gravel.
Modern asphalt roads and highways were the result of the work of two Scottish engineers, Thomas Telford and John Loudon McAdam. Telford designed the system of raising the foundation in the center to act as a drain for water. Thomas Telford (born 1757) improved the method of building with broken stones by analyzing stone thickness, road traffic, alignment and gradient slopes. Eventually his design became the norm for all highways everywhere. John Loudon McAdam (born 1756) designed it using broken stones laid in symmetrical, tight patterns and covered with small stones to create a hard surface.
Today, 96% of all paved highways and streets in the U.S. - almost two million miles - are surfaced with asphalt. Almost all is obtained by processing crude oil. After everything of value is removed, the leftovers are made into asphalt cement for pavement.
The first use of asphalt in this purposes occurred in 1824, when blocks were placed on the Champs-Élysées in Paris. Modern asphalt was the work of Belgian immigrant Edward de Smedt at Columbia University in New York City. By 1872, De Smedt had engineered modern "well-graded," maximum-density asphalt. The first uses of this were in Battery Park and on Fifth Avenue in New York City in 1872 and on Pennsylvania Avenue, Washington D.C., in 1877.
