Novachip was a French process utilizing a unique paving machine manufactured in Germany. This machine simultaneously applied an evenly distributed asphaltic emulsion and a thin lift of hot mix to the existing roadway surface.
The project extended five and a quarter miles on Louisiana Highway 308 parallel to Bayou LaFourche. The project began September 8 and ended September 10, 1997. The highway was 22 feet wide with the paving beginning just north of Raceland. The site was selected for its sound base and moderate to heavy traffic that is heaviest in the months of October and November. The existing pavement was a plant mix seal with Tennessee slag aggregate laid by T. L. James in 1978. This surface has performed beyond its expected life. There were areas in this project with up to 250 feet of longitudinal cracks greater than 1/4 inches. there were also some areas of aggregate loss on the old surface. Other sections of the road were patched by maintenance. Beneath the plant mix seal was about 7 inches of hot mix on a sand shell base.
