The Novachip (Trademark) is a surface treatment process that was developed in France in 1986. This process increases skid resistance and seals old pavement surfaces, and since 1986 has been used widely in Europe on high-speed, high-volume roadways. This paper documents the 5-year performance of two surface treatment types: the Novachip (Trademark) and conventional mill and overlay treatments on routes with similar average daily traffic (ADT) and service life. Three projects located on state route LA-308 in Lafourche Parish were selected for this evaluation. The performance indicators considered included rutting, alligator cracking, random cracking, transverse cracking, and smoothness as determined by international roughness index (IRI). A Life-Cycle Cost Analysis (LCCA) was conducted in order to compare the Novachip (Trademark) surface treatment process with the conventional surface treatment process of mill and overlay. In general, both surface treatments provided similar performance indicators as measured by rutting, cracking (alligator, random, transverse), and IRI. Based on the LCCA, the Novachip (Trademark) surface treatment provided significant cost savings when compared to the conventional surface treatment process of mill and overlay.
