My first father-in-law (b. Bavaria, 1899) used "colprovia" (which I had always assumed was Germanic Kohlprovia--but a google search reveals it's a kind of asphalt). The term "blacktop" differentiates by color in comparison with "white" concrete. _________________________________ "Raffiniert ist der Herr Gott, aber Boshaft ist er nicht" --Albert Einstein
