Inspection And Evaluation Of A Bridge Deck Reinforced With Carbon Fiber Reinforced Polymer (Cfrp) Bars, Choo Ching Chiaw, Issam E. Harik
Inspection And Evaluation Of A Bridge Deck Reinforced With Carbon Fiber Reinforced Polymer (Cfrp) Bars, Choo Ching Chiaw, Issam E. Harik
Kentucky Transportation Center Research Report
Cracking in reinforced concrete decks is inevitable. It leads to the corrosion and eventual deterioration of the deck system. The use of non-corrosive reinforcement is one alternative to steel in reinforced concrete construction. This report deals with the field evaluation and performance of a concrete bridge deck reinforced with carbon fiber reinforced polymer (CFRP) bars. The bridge is identified as the Elkin Station Road Bridge on route CR1210 over the Two Mile Creek in Clark County, KY. The CFRP bars were placed in the top and bottom mats of the bridge deck in both the transverse and longitudinal directions. The …

Evaluation Of Work Zone Safety Operations And Issues, Jerry G. Pigman, Kenneth R. Agent, Eric R. Green
Kentucky Transportation Center Research Report
Work zone activities are one of the areas with a high potential for compromised safety for workers and road users. Various measures have been taken to increase the level of safety in work zones; including the use of double fines for speeding and the application of speed displays based on radar detection. There has been an effort to improve the effectiveness and safety of flaggers by requiring the use of a stop/slow paddle for most work zone conditions, using lights on the paddle, and increasing visibility by using more reflective clothing. It has been suggested that safety in work zones …
Evaluation Of Alternative Water Resources For Cape Coast And Its Environs In Ghana, Alex Kumah
Evaluation Of Alternative Water Resources For Cape Coast And Its Environs In Ghana, Alex Kumah
Electronic Theses and Dissertations
Cape Coast once a national capital of Ghana and its environs in recent years have constantly suffered perennial acute water shortage. The Brimsu dam which takes its supplies from the Kakum River with current production capacity of 1.4 × 104 m3/day cannot meet the water needs of the study area. The operating levels of the dam during crisis have reduced from 7.3 meters to 4.7 meters over the years with subsequent reduction in water production by 35%. Recently, the operating level has reduced further to about 3.5 meters with 60% reduction in water supply. This study evaluated alternative water resources …

JTRP Technical Reports
With properly designed LIDAR control, assessment of 3D as-builts is attainable with an average over-all horizontal (planimetric) error of 0.324 ft (9.9 cm). Specifically, with an RMS error of 0.284 ft (8.7 cm) in Northing, and 0.255 ft (7.8 cm) in Easting. The average over-all vertical (height) error is 0.003 ft (0.1 cm) with a 0.108 ft (3.3 cm) RMS error. Lidar recognizable control (2m x 2m chevrons) was spaced at approximately 200m parallel to the direction of the axis of the project corridor, and at 60m sideway intervals. The project corridor was about 6 km long. Least Squares Image …
