To protect waterways adjacent to construction projects with disturbed land, a 50 ft (15 m) vegetated buffer or equivalent sediment controls are required. However, there is little guidance on the effectiveness of vegetated buffers in removing sediment or how sediment barriers can aid shorter buffers or replace buffers. A modeling methodology was developed and used to determine the performance of 11,664 50 ft (15 m) vegetated buffer configurations with Nebraska conditions; sediment capture averaged 92.6% and ranged from 18.5% to 99.5%. To determine the performance of Nebraska Department of Transportation standard and modified sediment barrier installations, a large-scale testing methodology …

Most of the deficiency in existing stringer-type bridges lie in deterioration of the bridge deck. Cast-in-place reinforced concrete decks experience cracking shortly after construction due to large differential creep and shrinkage with the supporting beams, and due to the temperature drop experienced during the hydration cycle. The NUDECK (Nebraska University) system is a full-depth precast/prestressed concrete bridge deck panel system. The combination of high performance precast concrete, where little creep and shrinkage occur after the deck is made composite with the beams, and two-way prestressing assure continued pre-compression of the deck during its life. With this system, construction time and …
