WARSAW — The orange road construction sign looked official with its neon color and placement at the edge of South Washington Street and West Market Street.

But with the words, “Road Preservation Ahead,” it also subtly marketed Rejuvtec, an Indianapolis company that works with municipalities to extend the life of asphalt by spraying an additive.

The company on Wednesday applied the treatment to pavement on parts of Clark Street, Colfax Street, Main Street, North Bay, Willow Lane, Park Avenue, Spring Hill Road and Sunset Drive, according to information provided by the city.

Rejuvtec, which has customers in Indiana and Kentucky, uses “maltene replacement technology.”  Maltenes act as the “glue” that binds asphalt pavements together, imparting flexibility, fluidity and adhesion properties, according to the website pavetechinc.com.

A spokesperson for Rejuvtec said they applied the solution to about 80,000 square yards of pavement.

The mixture has a red tint when applied, but once it soaks into the asphalt, it turns a dense black.

Sand, which is applied to reduce slipping afterward, was to be swept up soon afterward.

A contract for work with Rejuvtec was approved by the Board of Works and Safety in May for $87,395.
