Evaluation Of Sustainable And Environmentally Friendly Stabilization Of Cohesionless Sandy Soil For Transportation Infrastructure, Miladin Radovic, Anand Puppala, Surya Sarat Chandra Congress, Jungyeon Jang, Oscar Huang

Data

Ordinary Portland cement (OPC) is generally used to stabilize cohesionless sandy soils that are often found in coastal areas. Due to its high carbon footprint, many studies are being conducted to identify a suitable green alternative for stabilizing cohesionless soils. Previous studies have shown that partially replacing OPC with waste materials such as nano-silica and coal waste reduces the overall carbon footprint without significantly impacting the performance. Geopolymer (GP) received a lot of attention in the past few decades owing to its similar properties to that of OPC yet with a lower carbon footprint. This study investigated the feasibility of …

Eco-Friendly Stabilization Of Sulfate-Rich Expansive Soils Using Geopolymers For Transportation Infrastructure, Xinbao Yu, Anand Puppala, Miladin Radovic, Sayantan Chakraborty, Jungyeon Jang, Oscar Huang

Data

Traditional calcium-based stabilizers, such as lime, to stabilize sulfate-rich expansive soils, are lasting-challenges in geotechnical engineering. The biggest problem with using calcium-based stabilizers is that when calcium and water are exposed to sulfate-rich expansive soils, they form ettringite as an expansive mineral, which causes sulfate-induced heaving. The study aimed to investigate the feasibility of stabilizing sulfate-rich expansive soils using geopolymers for transportation infrastructure. Literature review on sulfate-induced heaving and sulfate-rich soils stabilized with geopolymers suggests a direction for how to stabilize sulfate soils using geopolymers. The engineering tests were conducted to determine the swell, shrinkage, and strength behavior of natural, …

Development Of Geopolymer-Based Cement And Soil Stabilizers For Transportation Infrastructure, Miladin Radovic, Anand Puppala

Data

Corresponding data set for Tran-SET Project No. 18CTAM03. Abstract of the final report is stated below for reference:

"Geopolymer Cement (GPC) has drawn much attention in the recent years as an alternative to Ordinary Portland Cement (OPC) for soil stabilization, pavements, bridges and other transportation structures due to their good mechanical properties in comparison to OPC. In addition, GPC can be processed at room temperatures from aqueous solutions of waste materials (e.g. fly ash) or abundant natural sources (e.g. clay), thereby significantly reducing CO2 production associated with processing of OPC. As such, GPC proves to be a more sustainable and …

Use Of Recycled Crushed Concrete (Rcc) Fines For Potential Soil Stabilization, Lindeman Mark, Varilek Brandon, Lieska Halsey, Rick Gloe, Maria Olomi

Nebraska Department of Transportation: Research Reports

This study evaluated the use of Recycled Crushed Concrete (RCC) Fines for potential soil stabilization. Soil stabilization is the enhancement of subgrade stability to improve the constructability of successive pavement layers. Use of RCC fines may not only provide less costly alternatives for subgrade stabilization, but their use may also alleviate landfill disposal challenges.

Disposal Of Bridge Paint Residue, Theodore Hopwood Ii, Sudhir Palle

Kentucky Transportation Center Research Report

Paint residue generated by bridge maintenance painting commonly contains lead requiring the residue to be disposed of as a hazardous waste. Several alternatives are being investigated in this study, chemical stabilization and recycling as options for the Kentucky Transportation Cabinet (KYTC) to consider in addressing the waste stream generated by bridge maintenance painting operations.

In the initial portion of this study, four chemical stabilization materials were identified as candidates for xperimental/demonstration projects entailing maintenance painting. A recycling option was also provided. An experimental bridge painting project was let by KYTC to investigate the use of two chemical stabilizers and the …

Long-Term Monitoring Of Experimental Features, Subtask 2: Alexandria-Ashland Highway (Ky 9) Pavement Performance Monitoring, L. John Fleckenstein, Monica L. Osborne, David L. Allen

Kentucky Transportation Center Research Report

Construction on the AA Highway began in late 1985 and was completed in late 1990. Prior to construction, 30 different test sections had been designed into the highway for evaluation. The test sections contain 23 different characteristic qualities and different segment lengths. The segment lengths range from 1.28 to 9.13 miles and took one and a half to four years to complete each segment.

The sections were constructed from various pavement and shoulder designs. The designs are varied by parameters such as the type of subgrade stabilization, drainage type, surface class, surface aggregate, and more. The purpose for monitoring the …

Stabilization Of An Airport Subgrade Using Hydrated Lime And Fly Ash, Tony L. Beckham, Tommy C. Hopkins

Kentucky Transportation Center Research Report

A 457-m (1,500-ft) runway pavement extension is planned for the Georgetown-Scott County Airport (Marshall Field). The clay subgrade of the existing paved runway was stabilized with six percent (dry weight) hydrated lime. A request was made by the Kentucky Transportation Cabinet, Division of Aeronautics, to determine the feasibility of replacing a percentage of the hydrated lime stabilizer with fly ash for the extended runway subgrade. Kentucky Highway Investigative Task No. 27 was issued by the Transportation Cabinet to fund a laboratory study to determine the effects of partially replacing lime with Type F fly ash (FA). Using fly ash to …

Selection Of Design Strengths Of Untreated Soil Subgrades And Subgrades Treated With Cement And Hydrated Lime, David Q. Hunsucker, Tony L. Beckham

Kentucky Transportation Center Research Report

Selection of design strengths of soil subgrades and subgrades treated with cement or hydrated lime is a problem in pavement design analysis and construction because a variety of different types of soils may exist in a highway corridor and a wide range of different strengths may exist after the soils are compacted to form the pavement subgrade. The selected subgrade strength will largely affect the pavement thickness obtained from the design analysis, the future pavement performances, and the overall bearing capacities of the subgrade during construction and the pavement structure after construction. In developing the proposed selection scheme, a newly …

Evaluation Of Wick Drain Stabilization Of Approach Fill Foundation (Bullitt County), Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

The purpose of this study was to document construction procedures and evaluate the effectiveness of prefabricated wick drains for dewatering and stabilizing an approach fill foundation. Construction was observed and photologged. Foundation pore pressure was monitored with pneumatic piezometers. Settlement of the entire structure was monitored by use of control points on the retaining wall and pavement.

Construction procedures were acceptable. Wick drains have functioned as expected and the approach fill has been stable for approximately four years since construction.

Evaluation Of Wick Stabilization Of Approach Fill Foundation (Carroll County), Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

The purpose of this study was to document construction procedures and evaluate the effectiveness of wick drains as a foundation stabilization method. This effort was executed by use of field inspections, photologs, and instrumentation to monitor foundation and field response. Instrumentation included a multipoint settlement gage, settlement platforms, and vertical slope inclinometers.

This procedure was judged to be successful in that 90 percent consolidation of the deep foundation occurred within approximately 100 days. Construction procedures were generally satisfactory.

Portland Cement Stabilization Of Western Kentucky Gravels, Robert C. Deen

Kentucky Transportation Center Research Report

It has been known for some time that some Western Kentucky bank gravels perform rather poorly as base or shoulder material. In the fall of 1956, the Division of Research participated in the experimental design and evaluation of a group of ten rural highway base stabilization projects. Two of these projects, one in Ballard County and one in Marshall County involved the stabilization of Western Kentucky bank gravels with a bituminous material; AE-200, a mixing-type emulsion, was used.

The performance of these bitumirlous-stabilized gravels has not been entirely satisfactory. Even though little tendency was noted for the asphalt to bleed …
