105 routine pavement type selection procedures of state and local highway agencies. The performance examples, design tools, pavement selection type guidelines, construction guidelines and specifications, and training materials will all provide significant value-added technology to these engineers and managers regarding composite pavements.

106 4 Increased use of lower-cost local aggregates in the lower PCC layer because the lower PCC is no longer the wearing course that will polish. The higher quality PCC surface provides some protection from freeze–thaw damage and wet–dry cycling.
