Evaluation of emulsified asphalt for use in Saudi Arabia

Creator:: Al-abdulwahhab, Hamad I.
Abstract:: Saudi Arabia currently contains 31000 km (18600 mi) of paved roads and 42000 km (25200 mi) of agricultural roads, with the prospect of more roads to be constructed. The low population (6 million) compared to the large area of the country (2,253,300 km², 900,000 mi²) coupled with the high cost...

Testing and evaluation of flexural reinforcing bars terminating in columns

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

Scale effects on reinforced concrete beams strengthened for shear with discrete externally bonded carbon fiber-reinforced polymer U-wraps

Creator:: Dawson, Matthew Ryan
Abstract:: Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

Freeze-thaw durability of reinforced concrete deck girders strengthened for shear with surface-bonded carbon fiber-reinforced polymer

Creator:: Mitchell, Mikal Maxwell
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged freeze-thaw cycling. CFRP...

Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

Creator:: Senturk, Ahmet Ekin
Abstract:: Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

Framework for Measuring Construction Project Performance using Energy

Creator:: Nnaji, Chukwuma A.
Abstract:: Over the years, the performance of construction projects has been a main source of concern given the percentage of a project cost associated with poor project performance. As a result of the growing clamor to improve the output of the built industry, comprehensive studies have been conducted to examine the...

Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

Creator:: Gillins, Matthew N.
Abstract:: Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...

Rigorous 3D Point Cloud Quality Assessment

Creator:: O'Banion, Matthew S.
Abstract:: The capabilities of modern three-dimensional (3D) capture technology such as laser scanning and image-based 3D reconstruction are well suited to enhance the practice and research of civil engineering. However, given the often-overwhelming focus placed on the incredible capabilities of these tools and techniques, it is important to investigate the limitations...

Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

Creator:: Javadnejad, Farid
Abstract:: Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

A Full-Scale Experimental Investigation of the Bearing Performance of Aggregate Pier-Supported Shallow Foundations

Creator:: Martin, John P.
Abstract:: Aggregate piers have been used for centuries, with increasing occurrence in the last few decades. Their usage has been driven by land development demand and enabled through equipment and engineering improvements. Understanding the principles controlling bearing capacities and serviceability performance has been an ongoing area of interest for structures supported...
