Texas Successful Flexible Pavements
A Resource Database for Practitioners
Why a Database?
• Power of Databases

– Professional Development
– Specification Development
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
How This Database Can Help You
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.”
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…
How This Database Can Help You
But now there’s an alternative. You log into the Texas Successful Flexible
Pavements (TSFP) website.

While your twentieth-century self plods through the rolodex .….

…. the modern you searches the TSFP web site for “concrete overlay.”
You retrieve five pavements.
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.

Meanwhile, 20th-century you continues the research by phone .…
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.

But your twentieth-century self continues the telephone “research.” Ahhh,
the good old days…
What We Learned

• Information of Value
– All types of flexible pavements seen as highly
successful
– Database contains information about:
