Show GOOD ROADS FIND ASPHALT BY ACCIDENT Discovered in Switzerland and Used for Purpose of Extracting Valuable Valu-able Bitumen. Asphalt, thonizli covering thousands of miles of roads In all countries, was discovered quite by accident. In the middle of the last century It was found iu Switzerland In its natural state, and used for the purpose of extracting ex-tracting the valuable store of bitumen It contained. In time It was noticed that pieces of rock which fell from the wagons, and were crushed by the wheels, formed a very fine road surface sur-face when half melted by the heat of tbe sun. An experiment was mnde and a road of asphalt laid In Paris. It was so successful that the new road material became adopted through all the big towns of Europe. All sorts of materials have been tried since, from rubber to seaweed. It is very likely, In fact, that In the future the streets of our big cities will be paved with some form of rubber rub-ber mixture which will be practically noiseless. Very extensive experiments have already been carried out with such a mixture. In New York several streets ara paved with steel, and a steel road has been in use in Valencia, in Spain, for the last 20 years. Perhaps the most curious material for a road is sea weed. This compressed into solid blocks, Is used to pave the street of Baltimore. These seaweed blocks ara bound with wire and dipped Into bolV lng tar before being put to use. |
