• Abstract:
  In July & August, 2010, MaineDOT applied 4.75 mm. (5/8 inch) Superpave designed hot mix asphalt ; overlays in three locations. These overlay projects were on Route 1A, 2A, and 27, located in Forkstown, ; New Portland, and Limestone, respectively. Project ID numbers are 016814.00, 017314.00, and 016809.00. ; The specific lengths designated for the treatments are: ; ƒ-Forkstown Twp. to TA R2 WELS, Route 2A, 5.5 miles ; ƒ-New Portland to Kingfield, Route 27, 5.51 miles ; ƒ-Limestone to Caswell, Route 1A, 3.79 miles ; These projects were completed under the MaineDOT Regional Highway program as highway preservation ; projects. These three projects were unique in that the mix design specified 4.75 mm (5/8 inch) aggregate ; rather that 9.75 mm aggregate which is more commonly utilized. This small difference could lead to cost ; savings, if the change results in equivalent performance. The intent of these trial applications are to ; determine how the mix performs under Maine conditions.
