Compatibility of Materials for Restripe Situations
All pavement marking materials will at some point reach the end of their useful life. On many occasions, rather than obliterating the existing stripe, it is more cost-effective and convenient to simply restripe over the old markings without removing them, assuming that the old markings still adhere well to the roadway. However, for restriping to be effective, the material that is to be applied must be compatible with the existing pavement marking material. Table 2-3 shows a matrix of material compatibilities.
