Coarser Gradation

Coarser Gradation

Finer Gradation, increased #100 & #200, increased AC by 0.3%

Increased AC and finer gradation

Decreased AC, coarser gradation

Test Strips that failed on the “Project” were removed.

Note: Compaction Test Strips completed on each project to establish roller pattern/effort.

The use of Belly Dumps & a Material Transfer Device (MTD) provide improved pavement quality


Special screed extension allowed paving under the guardrail


Sampling behind the paver is an issue


Establishing compactive effort


The contractor achieved the goal of a smooth & consistent surface


longitudinal joints were double tacked and then “Pinched” withtacked and then Pinched with rollers. Density at joint between 92% -94%

MTD used with End Dumps


End Dumping to MTD worked well for reducing segregation, but still increases surface roughness.


Experimenting with FLIR Thermal Camera. Difficult to p gdetect thermal segregation when air temperature is 100

degrees plus
