  1. Texas Successful Flexible Pavements A Resource Database for Practitioners

  2. Why a Database? • Power of Databases • Relational • Searchable • Expandable • Accessible (Web browsers) • Applications • Professional Development • Specification Development

  3. 0-5472: The Project • Purpose • To develop a database for successful pavement sections in Texas – including both experimental and non-experimental pavements • Objectives • Define “successful” flexible pavement performance • Select a representative group of particularly successful Texas flexible pavements for in-depth study • Develop a database with web site access for the successful flexible pavement information • Analyze and learn from the selected pavements

  4. How This Database Can Help You

  5. How This Database Can Help You Let’s say that your district engineer walks into your office and says, “We’ve got a series of expressway overlay projects in planning right now. The overlays we put down three and four years ago just don’t look to me like they’re going to hold up as well as we’d hoped. I’d like you to compare what we have been using to what other districts are doing and see if we are missing anything.”

  6. How This Database Can Help You Way back in the twentieth century, you’d probably call a district pavement engineer buddy in another district to see what they have been doing. The district pavement engineer in the other district tells you what they are doing, but that’s only one person. You’ve got a lot more phone calls to make. Boy, this research is going to take a while…

  7. How This Database Can Help You But now there’s an alternative. You log into the Texas Successful Flexible Pavements (TSFP) website.

  8. How This Database Can Help You While your twentieth-century self plods through the rolodex .….

  9. How This Database Can Help You …. the modern you searches the TSFP web site for “concrete overlay.”You retrieve five pavements.

  10. How This Database Can Help You You find what other districts have rated highly enough to have placed the information into the database. You notice that one district used an SMA mix, and that it has performed quite well. That possibility peaks your interest. After studying the SMA pavement information on the web site, you contact that district’s pavement engineer for a little more information and confirmation of your thinking.

  11. How This Database Can Help You Meanwhile, 20th-century you continues the research by phone .…

  12. How This Database Can Help You You report later that day to the district engineer that the approach used in your district in the past is pretty well on par with what most everyone else has found successful, but that SMA is a possibility that your district hasn’t tried that appears worth a look on a future project.

  13. How This Database Can Help You But your twentieth-century self continues the telephone “research.” Ahhh, the good old days…

  14. What We Learned

  15. What We Learned • Information of Value • All types of flexible pavements seen as highly successful • Database contains information about: • 6 Thick ACPs • 6 Thin ACPs • 5 Concrete Pavement Overlays • 8 Surface Treatment Pavements • Database provides information about the local conditions where various pavement types have been particularly successful

  16. What We Learned • Locations of Pavements in the Database

  17. What We Learned • Specification Criteria Evaluation Value • Method provided for capturing valuable specification evaluation data • Graphical analyses provided
