Abstract:The NOVACHIPTM Surface Treatment process was developed by SCREG Routes STP in France in 1986. NOVACHIPTM is a registered trademark of Societe Internationale Routiere, which is a subsidiary of SCREG Routes STP. This process was developed to increase skid resistance and to seal old pavement surfaces [2] and, since 1986, has been used widely in Europe. It is used as a surfacing on high-speed, high-volume auto routes and the national route systems. It is also successfully used in curb and gutter sections in cities. Engineers from the United States were first introduced to the NOVACHIPTM process through a demonstration given during a European Asphalt Study Tour in 1990. The first NOVACHIPTM projects in the United States were constructed in the state of Alabama in the fall of 1992, with a machine imported from France. Test sections were also constructed in Mississippi and Texas in the same time frame using the same machine from France used in Alabama. Louisiana’s first NOVACHIPTM project was completed in September 1997. The initial NOVACHIPTM paving process used in the United States and Louisiana was proprietary and licensed through KOCH Materials Company, Inc. Louisiana, partnering with KOCH Pavement Solutions, has since developed a non-proprietary special provision specification using this process. No longer described as NOVACHIPTM in Louisiana, it is now an Ultrathin HMAC Wearing Course.
This report documents the six-year performance of the NOVACHIPTM Surface Treatment Process when compared to conventional mill and overlay systems with similar Average Daily Traffic (ADT) and age. The performance evaluation period considered were from 1997 through 2003.
