FY 2014 TRC Projects

TRC 1401:

 

TRC 1402:

Development of a Field Exposure Site for Predicting and Mitigating ASR Damage   Economic Feasibility and Increased Sustainability of Short Span Arch Culverts
 
TRC 1401 deals with the detrimental effects of alkali-silica reaction (ASR) and will provide not only preventative measures for future concrete structures, but ways to mitigate the existing damage as well. TRC 1402 studies short span arch culverts as an economically viable and environmentally sound alternative to box culverts. It calculates construction and life cycle costs of both short span arch culverts and box culverts, and determines which type of culvert are the most economically viable and environmentally sound for different topographic situations. 



     

     

TRC 1403:

 

TRC 1404:

Development of Best Management Practices for Turbidity Control during Rainfall Events at Highway Construction Sites Using Polyacrylamide   Evaluating Performance of Asphalt Pavement Based on Data Collected During IRP
 
TRC 1403 will develop Best Management Practices (BMPs) for the control of topsoil which is washed away by irrigation runoff, creating turbid water. The project will focus on the use of PAM (polyacrylamide) to bind soil particles together and prevent them from being carried away in runoff water.   TRC 1404 will look at cores that were collected throughout the interstate rehabilitation program (IRP) which exhibit signs of severe cracking. The data from these cores will be compared to that of the data collected by the Automated Road Analyzer (ARAN) and Falling Weight Deflectometer (FWD) to determine potential new performance tests that evaluate the quality of asphalt concrete mixtures.
     

     

TRC 1405:

 

 
Examination of Full-Depth Reclamation Techniques for Shale Areas across Arkansas​    

   
TRC 1405 will focus on the problems created by the large increase in traffic volume and weight in the Fayetteville shale and Brown Dense shale areas in Arkansas. Full-Depth Reclamation (FDR) is an option for potential rehabilitation in those areas that this project will further explore. Several different types of FDR mixes will be tested and evaluated to allow for heavier and more frequent traffic flow at those sites.
