Abstract
Tar for use in road construction is mixed with a small proportion of polyvinyl chloride which has not been subjected to after-chlorination. A highly polymerized polyvinyl chloride is preferably employed; it may be added to the tar, heated to 100 to 120 DEG C. either in solution, e.g. in anthracene oil or in powder form.
