摘要

A fiber especially suitable for reinforcing bitumen-containing materials which comprises a fiber of polyethylene terephthalate having a tenacity of at least about 7.5 grams per denier, an elongation at break of at least about 9 percent, an elongation of not more than about 5 percent under a load of 5 grams per denier and a shrinkage of less than 4 percent when kept under a tension of 0.05 grams per denier for 4 minutes at about 160 DEG C. Also a process for producing this fiber and a bitumen-containing structure reinforced therewith are disclosed.
