Research Product Implementation


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.

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.

Pile_CPT22.zip - Windows XP »

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.
