ADVANCED DIRECT QUALITY CONTROL FOR ASPHALT COMPACTION

Page 3: Avanzado control de calidad en compactación...•Asphalt compaction and challenges •Automatic optimisation of compaction (IC) •Continuous Compaction Control (CCC) - Compaction

Challenges: Wide range of asphalt mix designs

Dense-graded

Open-graded Gap-graded

Page 4: Avanzado control de calidad en compactación...•Asphalt compaction and challenges •Automatic optimisation of compaction (IC) •Continuous Compaction Control (CCC) - Compaction

S M A: Gap graded with

- % of crushed stones,

- mastic filler, sand and PmB.

- difficult to compact

Safety: Reduced vehicle spray and hydro-plane

Durable: For high traffic and heavy truck routes

Gap graded mix

Compaction methods

Static compaction (Tandems, PTR)

Dynamic compaction (fixed parameters)

Vibration, Oscillation

Intelligent compaction (IC) (automatic adjusting)

for asphalt and soil

Page 6: Avanzado control de calidad en compactación...•Asphalt compaction and challenges •Automatic optimisation of compaction (IC) •Continuous Compaction Control (CCC) - Compaction

• Unexperienced operators

• Too many passes

• Over compaction:

- pulverization of aggregates

- surface loosening effects

- fatting-up with bitumen

cracks
