SALT HIGHWAYS.
Highways of salt are now being built as the result of experiments by the International Salt Company of Ithaca, New York. The salt is either mixed with or inserted between layers of the road material and rolled to a firm surface. It draws moisture from the air and at the same time reduces the film of moisture around each particle of clay, so that the clay packs down harder. Once the salt has crystallised on the surface, the road shed* water during a rain and does not become slippery or muddy. It resists traffic abrasion to a marked degree. Salt roads can be built for around £00 a mile, whereas £300 is the minimum cost for a mile of asphalt road. A highly successful one, connecting Ithaca with its new airport, has been in use for the past two years.
