Inlaid tape is a 3M manufactured product which is applied to the surface while it is being paved. The tape is rolled into the surface, embedding it into the aggregate.
Inlaid tape is considered the most durable product, with the best reflectivity
characteristics. Since the tape is manufactured in a controlled environment, free from human error, 3M provides a 5 year warranty on both its service life and reflectivity. It is the only product in the pavement marking industry that provides a warranty period of that length.
Inlaid tape is commonly used on township roads, county roads and state highways. This material is the most expensive of all the pavement marking materials available, due to its manufacturing costs and the labor cost associated with the installation of this product.
