Geotechnical Testing happening for U.S. 51 Ohio River Cairo Bridge Replacement Project in Kentucky

The Kentucky Transportation Cabinet (KYTC) announced last week that geotechnical testing for the project was to start at the end of June. The testing includes field work and drilling in the river upstream from the existing bridge. According to the release, crews are driling and testing soil samples from ground level to as deep as 400 feet below the riverbed. Drilling is taking place 24 hours a day, seven days a week, until the work is complete. “Because of the area’s complex river conditions, a lift boat will be used to minimize the impact on passing Ohio River towboat traffic,” the release stated. “The geotechnical work is expected to take a couple of months, but the schedule is dependent on river levels. The geotechnical testing will provide a better analysis of the soils under the river and existing geological conditions, which will give engineers the information necessary to design the foundations for a new bridge.” The work will have no impact on vehicle traffic crossing the existing bridge. The geotechnical work comes as the U.S. 51 Bridge Project Team has scheduled a meeting to update the public on planning for construction of a new bridge. Among other things, the team plans to share the bridge design type for the new structure that could start construction in 2028. Photos and display materials will be available online at https://us51bridge.com/ after the public meeting. The existing U.S. 51 Ohio River ‘Cairo’ Bridge serves as a north-south connector for U.S. 51 and an east-west transportation corridor for U.S. 60 and U.S. 62. The bridge carries about 5,400 vehicles per day between Kentucky and Illinois. About 43 percent of the traffic is commercial trucks. The bridge crosses the Ohio River at navigation mile point 980.4 and carries U.S. 51, U.S. 60, and U.S. 62 [...]

Streets & Drainage Update: Drilling for Geotechnical Borings – Lakesider Ohio News

The first phase of the Lakeside Streets and Drainage Project begins in fall 2024. To plan engineering work and street construction, drilling for geotechnical borings on east Lakeside will start in late March. Geotechnical boring is a process that involves drilling into the soil and evaluating the soil, rock, groundwater and overall conditions at a given depth and location. We are determining how close rock is to the pavement surface and if it could impact the project design. The project designer, Contractors Design Engineering (CDE), selected 32 locations for borings where they are concerned that rock might impact their design. “There are consistent places on the north-south streets where there’s a hump in the road that causes water to drain from the north to the south,” Seling said. “If they’re going to cut that knob down, we need to know how close the rock is to help determine if the road can be lowered to improve drainage or if the rock would substantially increase the construction cost. We can also alert the contractor about the depth of rock ahead of time so they can base their proposed cost on that situation to avoid cost increases during construction.” Geotechnical drilling Ohio contractor will provide the service. They will field stake test locations and utilities will be cleared by the Ohio Utilities Protection Service. Wertz will bore holes in the pavement, then restore them by backfilling with spoils and/or compacted stone to within 12-inches of the surface and then backfilled with asphalt cold patch to grade. The plan is to drill up to 5 feet unless they hit rock first. It will take up to three days to complete the work.

Long-Term Testing Of Concrete Bond Durability

Source: Long-Term Testing Of Concrete Bond Durability The definition of concrete durability can be explained as the ability of a specimen to resist any form of weathering action, namely abrasion, chemical, physical, or any other process of deterioration. In other words, the durability of concrete can also be defined as the ability to last a long period of time without significant deterioration or failure. Image Credit: Peshkova/Shutterstock.com Types of weathering include mechanical, physical, and chemical weathering of concrete including the alkali-aggregate reaction of sulfate attack and chloride attack. Different long-term testing methods have been used over the years and more research has been done to improve the existing methods to be more economical and environmental. Consideration has also gone into methods that reduce the time in which these tests can be completed and assessed. The Importance Of Long-Term Durability Testing It is important to test for the durability of concrete bonds because of the following reasons. Firstly, concrete testing will allow the designers to determine accurately the lifespan of a specific structure according to its specific needs or requirements. If a structure is intended to last a specific period of time, long-term concrete testing can reveal the combination that is required for it to last that long. There can be economic and environmental benefits to this testing. Economically, constant rehabilitation and patching up of structures are very expensive. Hence, long-term testing can reveal the right combination of concrete mixtures for durable structures, thereby reducing the number of times for rehabilitation. Environmentally, constant rehabilitation will require more use of natural resources such as sources of energy, gypsum, or steel to continuously rehabilitate worn-out structures. Continued rehabilitation increases the carbon footprint, which is not environmentally friendly. Developments In Concrete Bond Materials New studies have revealed that the addition of carbon fibers amounting [...]

Crews wrap up yearslong landslide project on Columbia Parkway in Cincinnati, Ohio

Source: Columbia Parkway Hillside Stabilization - Transportation & Engineering Source: Crews wrap up yearslong landslide project on Columbia Parkway Crews have wrapped up construction on a years long project to stabilize a large swath of hillside along Columbia Parkway in Cincinnati, Ohio — a stretch that has long been a landslide risk. Contractor crews officially wrapped up the $17.6 million project this week, city officials announced. The project’s footprint extends over two miles on the uphill side of the parkway from Bains Street near downtown to just east of the William Howard Taft Road-Torrence Parkway intersection in East Walnut Hills. Cincinnati’s Department of Transportation & Engineering began developing a long-term stabilization plan for the parkway in the spring of 2019 following a series of landslides in multiple locations along the uphill side. Landslides in the area began increasing in frequency and significance in recent years, peaking in the winter and early spring of 2019. The threat to public safety also was increasing with mud and debris frequently spilling over existing retaining walls onto the roadway, prompting emergency closures along the five-lane thoroughfare that carries approximately 30,000 vehicles a day from the city’s east side into downtown. The parkway was built in the late 1930s as a Depression-era public works project situated along a bluff overlooking the Ohio River. The Ohio River traces a path along Illinois, Indiana, Kentucky, Ohio, Pennsylvania, and West Virginia. Mitigation efforts in the 1990s helped reduce the impact of landslides on the downhill side of the parkway but didn’t address the uphill side. City council approved funding for an emergency mitigation project in late spring 2019 and it started to take shape that summer once Canton-based Beaver Excavating was selected as the prime contractor. The proposed dual solution including soil nailing for the steepest sections, and [...]

Using Torque Testing for Better Designs

Source: Using Torque Testing for Better Designs All Engineers can relate to an experience we’ve had where what we designed was not how it turned out in “the real world”. Rarely does a project end up being exactly as what we put down on paper. Soil testing for foundation supports is no exception and unfortunately these differences almost never end on the positive side of a cost estimate. One way to mitigate those differences is to use a testing process which directly relates with the type of foundation being used. For helical piles, while there are well-established trends between ASTM D1586 N60 blow count N values and potential pile length, even the slightest variations in testing methods and/or soil description can create significant differences in the “design” versus “reality”. The more accurate method for a helical pile foundation design would be to do actual torque tests (a.k.a. helical probe tests) at the site. While most designs initially begin with a Geotechnical Report including boring logs, for helical piles using an actual torque test prior to start of work instead will provide a much more accurate picture of soil capacity and allow for a finite design. Even with boring logs and N60 blow counts being used for preliminary designs, a torque test can be used to “fine-tune” the foundation design. Many owners might think that the additional cost associated with a site torque test, albeit nominal, is not needed. However, time and time again, the small additional cost has proven to save substantial money on the foundation project by allowing the engineer to confirm and enhance their foundation design. In addition, site torque tests can be incorporated directly into a design created in the HeliCAP® v3.0 Helical Capacity Design software to provide real time updates to designs giving better solutions with more confidence. Adding actual [...]

Ohio Geotechnical engineering faculty to develop course with Japanese colleagues

Source: Geotechnical engineering faculty to develop course with Japanese colleagues | Civil, Environmental and Geodetic Engineering Geotechnical engineering faculty to develop course with Japanese colleagues Posted: July 20, 2020 Thanks to an award granted by a partnership of The American Council on Education (ACE) and the Institute for Innovative Global Education, Ohio State faculty and students will have soon have the opportunity to collaborate with their colleagues and peers at the University of Tsukuba in Japan. The two universities were selected by ACE to participate in the U.S.-Japan Rapid Response Virtual Exchange / Collaborative Online International Learning (COIL) Transformation Lab. The COIL program fosters U.S.-Japan higher education ties through the development of new and innovative courses. Daniel Pradel Daniel Pradel, professor of practice in geotechnical engineering, will collaborate with Takashi Matsushima, professor of engineering information and systems at the University of Tsukuba, to adapt a current Ohio State course called, “Learning from disasters: Extreme events and their impact on infrastructure, engineering, and society.” Professor Pradel previously participated in several post-disaster, engineering reconnaissance teams, including the 2015 Ghorka Earthquake in Nepal, the 2011 Tohuku Earthquake and Tsunami in Japan and 2017 Hurricanes Irma and Maria in Puerto Rico. He said that studying the response to these and other extreme events will reinforce, to students, the importance of resilience in designing and developing infrastructure. "Historical decisions in planning, engineering and/or urban development play important roles that often magnify the destructive effects of extreme events," Pradel said in a statement. He went on to emphasize the other challenges these events present. "In developing countries, where resources tend to be limited, extreme events such as earthquakes and typhoons often result in medical threats from infectious diseases due to the limited availability of clean water and emergency medical services." Daniel Pradel surveys landslide damage caused by Hurricane Maria, Puerto Rico, 2017. While international travel is not possible during [...]
