Information from Nat Bodian:

        In 1870, an historic happening occurred on Broad Street, Newark.  America's first recorded asphalt pavement was placed in front of Newark City Hall by Edmund j. DeSmedt, a Belgian chemist.  Thirty-four years later, in 1904, asphalt pavement covered only 141 miles of American roads.  By 1916, however, asphalt pavements were commonplace.
