LTRC research projects often result in outcomes delivered via software or web applications, spreadsheets, and end-user tools, among others. These items are housed here on the research product implementation page for easy reference.
GIS Web Application for Synthesis of Fault Traces in SE Louisiana
Visit GIS web app »
Southeast Louisiana faults spatially located as research results from Louisiana Transportation Research Center (LTRC) project 18-3GT and Tran-SET Project No. 17GTLSU12. The research project spatially located fault interpretations from previous studies and scientific journal publications. Descriptive criteria for reliability of fault locations were developed and are based on resources used in the interpretation and map scale: Level 1 suspected faults – described in the literature and included here from georeferenced maps; Level 2 identified faults – those observed on 2D or 3D seismic and mapped in a geographic reference system; Level 3 confirmed faults – mapped on seismic and ground-truthed with field methods including age-dated sediment borings and high-resolution seismic. Research project full report and author citation is available at: https://digitalcommons.lsu.edu/transet_pubs/30.

Corrosion Map for Metal Pipes in Coastal Louisiana
Visit GIS web app »
A combination of data, obtained from field surveys provided by the Louisiana Transportation Research Center and Web Soil Survey Data provided by the Natural Resources Conservation Service, was used to create an interpolated GIS surface representing zones of corrosion potential to metal culverts. The corrosion potential was calculated for coastal Louisiana based on soil properties. Areas of similar corrosion behavior were grouped together based on expected life span of metal pipes and were classified accordingly.

Louisiana Roadway Tree Distress
Visit GIS web app »
This GIS web application displays layer of roadway distress resultant from tree growth as reported to LTRC for project 12-2P.
***This dataset is not all inclusive as it is dependent upon reporting from the LADOTD districts.***
The roadway distress information can be searched by LADOTD District number or LADOTD Control Section number. Additionally, the soil properties for subgrade materials developed under the NCHRP Project 09-23B for all of Louisiana is included as a polygon layer for reference.

Louisiana Soil Classification by Cone Penetration Test - Soil CPT 4.0
Soil_CPT_Packages.zip »
LSC-CPT, Louisiana Soil Classification by Cone Penetration Test, is a software program developed for use on a Microsoft Windows platform. Five CPT soil classification methods were implemented into the software: Schmertmann (1978), Douglas and Olsen (1981), Robertson et al. (1986), and the probabilistic region estimation and fuzzy CPT classification by Zhang and Tumay (1999).

LPD-CPT, Louisiana Pile Design by Cone Penetration Test, is a design analysis software program developed for use on a Microsoft Windows platform. The program provides three analytical methods to predict the load capacity of driven precast concrete piles using electronic cone penetration data. The methods are: deRuiter/Beringen, Bustamante/Gianeselli (LCPC), and Schmertmann.

Updated Louisiana Pile Design by Cone Penetration Test
Pile_CPT_Packages.zip »
Updated LPD-CPT, Updated Louisiana Pile Design by Cone Penetration Test, is an updated version of the design and analysis software program developed for use on a Microsoft Windows platform. The program included eight pile-CPT methods: LCPC, ERTC3, Probabilistic, Philipponnat, De Ruiter and Beringen, Schmertmann, and modified Schmertmann methods, in addition to the combined method. The software can plot the ultimate pile capacity with depth for three different scenarios: no pre-bore, pre-bore (casing), and long-term scour condition. The LPD-CPT software was also updated to include batch analysis for the different bents in a bridge. The current version of the software is under testing phase.
