Current Research Projects
707 A GIS-based Mitigation Forecasting Tool and Study on Advanced Mitigation Processes used by DOTs
  Dr. Jonathan L. Goodall, University of South Carolina, February 8, 2013 – February 7, 2016
Objective: To develop a mitigation forecasting tool that leverages GIS and geospatial data to forecast project impacts and mitigation credit demands and review current practices in advanced compensatory mitigation planning in various DOTs and research journals.
704 Evaluating the Use of High Speed Laser Line Sensors for Improved Rideability Measurement
  Dr. Andy Johnson, SCDOT, December 3, 2012 – June 2, 2015
  Objective: Sensors that scan an entire tire width at speeds sufficient for high-speed use have recently become available. However, it is unknown if this type of sensor provides the same readings as the single-point sensor on conventional surfaces. The objective of this research is to assess the new wide-type sensors to evaluate if they can provide improved accuracy on all pavement types.
703 The Evaluation and Specification Development of Alternate Modified Asphalt Binders in South Carolina
  Dr. Serji Amirkhanian, Tri-County Technical College, November 16, 2012 – November 15, 2014
  Objective: To determine if available alternate modifiers will provide the same or better performance than the SBS modified PG 76-22 and to determine what affect additives such as natural sand, LASA and hydrated lime have on asphalt mixture performance. The alternate additives available to modify a base asphalt should be tested to ensure that the SCDOT is getting good quality material in order for asphalt mixtures to last their design life or greater.
  702 Compliance with the United States Environmental Protection Agency (USEPA) Effluent Limitation Guidelines – Turbidity Control and Surface Outlets
  Dr. Charles V. Privette, III, Clemson University, December 1, 2012 – November 30, 2015
Objective: To evaluate turbidity and surface water withdrawal associated with Department construction site stormwater discharge.
701 Development of a Guidance Manual for Assessing Scour using the South Carolina Regional Bridge-Scour Envelopes
  Stephen T. Benedict and Noel M. Hurley, Jr.,USGS, December 1, 2012 – January 31, 2016
Objective: To develop an integrated procedure for assessing scour potential at riverine bridges in South Carolina utilizing the regional bridge-scour envelope curves developed in the three previous field investigations (Benedict, 2003; Benedict and Caldwell, 2006; Benedict and Caldwell, 2009)
Validation of Contractor HMA Testing Data in Materials Acceptance Process-Phase II
  Dr. James Burati, Clemson University, August 24, 2011 - August 23, 2013
Objective: To recommend guidelines to utilize contractor HMA test data for materials acceptance based on statistical analysis of verification test results, split-sample test results, and computer simulation analyses.
Ranking of Pavement Preservation Methods and Practices
  Dr. Brad Putman, Clemson University, June 1, 2011 - May 31, 2013
  Objective: To identify methods to improve the implementation of pavement preservation strategies on asphalt concrete roadways in South Carolina.
694 Study of the Rate of Deterioration of Bridges and Pavements as Affected by Trucks
  Dr. Ronnie Chowdhury, Clemson University, May 15, 2011 - May 14, 2013
  Objective: To represent the impact of heavy vehicle traffic on pavements and bridges in South Carolina and to create policy recommendations informed by technical analysis as well as the modern political and institutional environment in South Carolina.
693 Operational and Safety Characteristics of Lane Widths
  Dr. Wayne Sarasua, Clemson University, March 1, 2011 - February 28, 2013
  Objective: To research the effects of travel lane widths on the safety and operations of non-interstate primary and secondary state routes in South Carolina.
692 Real Time Measurement of Scour Depths around Bridge Piers and Abutments
  Dr. Abdul Khan, Clemson University, January 3, 2011 - January 2, 2015
  Objective: To develope an accurate and reliable real-time scour monitoring system.
691 Improving Techniques to Estimate the Magnitude and Frequency of Floods on Urban Streams in SC, NC, and GA.
  Mr. Noel Hurley, USGS, May 3, 2010 - May 2, 2013
  Objective: The specific objectives of the investigation are to (1) update the magnitude and frequencies of peak-flows at urban stations, (2) update basin characteristics for the urban stations using consistent geographical information system (GIS) methods, and (3) update the regional urban-flood-frequency equations forthe 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence-interval flows.
689 Impact of Course Aggregate Gradation on PCC Performance Properties
  Dr. Prasad Rangaraju, Clemson University, July 1, 2010 - September 30, 2012
  Objective: To investigate how gradation variations outside the specified aggregate gradation bands influence the long term performance of concrete.
  686 Improvement to Acceleration Design Response Spectra (ADRS) for Seismic Design of Transportation Structures in South Carolina
  Dr. Ronald Andrus, Clemson University, December 1, 2009 November 30, 2012
Objective: To investigate and recommend Spectral Amplification Factors (SAFs) for the Coastal Plain (Lower, Middle and Upper) and the Piedmont/Blue Ridge geologic provinces of South Carolina.
Evaluation of Utility Relocation Costs and Best Management Practices
  Dr. Lansford Bell, Clemson University, October 1, 2009 – July 31, 2011
Objective: To verify utility relocation costs and improve utility relocation practices in South Carolina.
Accelerated Bridge Construction - Precast Alternate for Flat Slab Spans
  Dr. Bryant Nielson, Clemson University, August 27, 2009 October 23, 2013
Objective: To develop a set of standard details for 30-foot precast spans that may be used on any roadway regardless of the traffic volume it carries.
Characterization of Storm Runoff from Selected South Carolina Department of Transportation Maintenance Yards
  Mr. Noel Hurley, Jr., USGS, October 5, 2009 - October 4, 2013
Objective: To collect sufficient stormwater water-quality and flow data to document the type, concentration, and event load of selected constituents transported from SCDOT maintenance yards by stormwater runoff.
Feasibility of Establishing a High-Speed Rail Corridor Connecting Florence, Myrtle Beach, and Charleston using Existing Rail Lines

Mr. Roy Tolson, SCDOT, September 15, 2008 - September 30, 2011

Objective:  To research the feasibility of identifying a corridor for the purpose of constructing and providing rail service on existing rail lines and/or existing railroad right‑of‑way in the eastern part of South Carolina.  The corridor is intended to eventually connect to and become a part of the nation's network of federally-designated high-speed rail corridors.
