Title: Process for making cold tar road coverings
IPC: E01C7/18
Filed: 1929-12-30
Abstract: A cold asphalt street covering is prepared by mixing together a tarry substance, a bituminous substance, and 10-12 per cent of hydrated lime calculated on the weight of the end product.  The lime may either be added dry or as milk of lime, consisting of 1/3 lime and 2/3 water.  If desired 10-15 parts of benzene may be added.  In an example, 100 parts tar, 25 parts of asphalt, and 40 parts of milk of lime of the above composition are mixed in a stirring machine.  A modification of the process consists in mixing dry hydrated lime, with the other ingredients, and adding water at a later stage together with road metal and the like.
