WNW MR& WN M-1 Q Highway 67 Fill was hauled to the Highway 67 embankment area using several Cat 777 haul trucks and several Cat 740 haul trucks. The structural fill material was placed in an approximately 18 to 14 inch lifts by Cat D1 OR, John Deere 1050 and Cat D8R Dozers. The Cat CS56B vibratory, 10 -ton, smooth -drum roller completed the minimum of four passes (Method Specification Applies) over the lift surface. It should be Noted: haul trucks, loaded and unloaded, drove over the backfill surface contributing to the overall compaction of the lift. In addition a Cat 3306 excavator equipped with a jackhammer (hammer hoe) broke up the oversize material encountered and a Cat D6R with gps graded and shaped the downstream slope of the toe berm. A Cat 773 water truck and a Cat 14H grader were observed working the fill area on occasion. A GPS dozer was observed shaping the western downstream slope of the embankment.
