Sampittic Surfacing

For several years the writer has been studying the uses (and results) of hydrocarbon compounds in road making, and has been impressed with the lack of standards by which to judge the various so-called “bituminous cements” offered for sale, as well as with the pressing need for such standardization. With the increased use of this cement has come the inevitable increase in the variety of trade compounds; moreover, with the change in traffic conditions, highway engineers tend to conclude that the need for such a proper cement, and its future use, are greatly increased. The writer, from personal inspection, is familiar with most instances of the use of hydrocarbon cements in road building in the Eastern States, and thinks it will not be disputed that cements of considerable variety have been used, and many differing results have been secured.
