4 What is Foamed Asphalt?

5 What are its Physical Characteristics

6 Foam Mix Design Process % Passing Sieve Size (mm

7 Foamed Asphalt Process In-Situ

8 Foamed Asphalt Process Cold In Place Recycling

9 Foamed Asphalt Process Plant Produced – KMA 200

10 Quality Control Plant Produced KMA-200 Consistency and Performance

11 QA/QC Overview Testing QA/QC considerations Structural layer coefficients Typical sections

12 QA/QC Fieldwork Verification of application rates Sample treated materials Cast briquettes at varying densities using Marshall hammer –3 briquettes at 50 blows per side –3 briquettes at 75 blows per side –3 briquettes at 112 blows per side Measure briquettes for wet density Complete density testing of reclaimed pavement using heavy-duty Marshall density, i.e. 75 blows per side

13 QA/QC Fieldwork cont. Moisture content testing –Completed at plant location –Completed during placement Verification of placement depths

14 QA/QC Follow-up Testing Briquettes are cured using same methods as completed during the mix design Strength testing completed for –Dry ITS –Soaked ITS –Soaked stability and flow

15 QA/QC Follow-up Testing Develop polynomial trend lines using strength and field wet density values Estimate in-place strength of SBC at each compaction test location –Dry ITS –Soaked ITS –Stability

16 QA/QC Structural Layer Coefficients

17 Questions / Discussion ?
