1. I took 3510 this Spring …What Can I do with it? A collection of work related to what you learned (or should have) in 3510

2. Analysis of Data Using Statistics  Field Density is a random variable How can we measure it? Nuclear Density Gauge Pavement Quality Indicator PQI vs.

3. Can the PQI be used instead of a nuclear density gauge? It will take 36 readings in the PQI to reach the same confidence interval as with 4 readings in the nuclear density gauge

4. Analysis of Aggregate Properties  Aggregates shape and gradation determine its bearing capacity Can it support a fully loaded Space Shuttle?

5. Can Aggregate Support a fully loaded Space Shuttle? Gradations close to the maximum density line have more contact points, thus are able to distribute the load

6. How to stop an airplane? Concrete can transforms kinetic energy into deformation

7. Aereated Concrete  High strength concrete is not for every one… High Concentrations of Tricalcium Aluminate can be used for lightweight concrete

8. Visco-elastic Materials Absorb Energy  Buckling Restrained Braces (BRBs) prevent buildings from excessive deformations Are new designs adequate?

9. Buckling Restrained Braces Energy caused by cyclic deformations induced during seismic events can be dissipated

10. Compatibility of Asphalt and Aggregates  Roads are affected by moisture damage Does Binder Grade affect performance?

11. Hamburg test to simulate behavior PolyPhosporic Acid increases the bond between the polar asphalt molecules and the aggregate, thus decreasing the potential for moisture damage.

12. Provide a smooth surface Durable and capable of withstanding traffic

13. Las Vegas Grand Prix (2007)  A special solvent-less emulsion was used to create a bonded wearing course

14. Cold In-Place Recycling  Quick and cost-effective road preservation City of Ogden 24 th Street

15. Fracture Mechanics Recycled asphalt layer provides some protection against Reflective cracking

16. Representative Volume Element  Can small asphalt mixture beams be used for quality control of paving materials?

17. Simple Quicker tests The bending beam rheometer (BBR) can be used to test small asphalt mixture beams and provide for quality control of materials during production and laydown

18. Coefficient of Thermal Expansion As the temperature drops, the concrete contracts leading to cracking. A new test was developed and evaluated to measure CTE

19. Emphasis in Materials?  Not a discipline on its own Transportation Structures Geotechnical Construction  Related Courses CVEEN 6920a: Construction Materials (S10?) CVEEN 7570: Advanced Materials (S10) CVEEN 5570: Pavement Design (F09)
