Illinois' new State Route 121, delayed 15 years by legal battles over location, is finally being constructed as a 14-3/4-in. full depth asphalt pavement placed directly on top of 12 in. of lime-modified subgrade. The high-production job requires up to 6200 tons of hot mix per day to feed the 24-ft-wide paver. The new mechanistic pavement design process (described in an insert with this article) was used. Details of the construction are presented in this article.
