Asphalt mix design (Marshall method):
Determination of optimum bitumen content.
Grading of asphalt mix components.
Stability, flow and voids in the mixture.
Asphalt tests during pavement execution
Stability, flow, density, and voids for compacted specimens.
Bitumen content and gradation of extracted aggregates from bituminous mixtures. Comparing the results with the specifications.
Asphalt tests after pavement execution
Determination of pavement thickness and field density by extracting cores from the roads.
Comparing the results with the specifications and determination of the compaction percentage of the executed pavement.
Bitumen tests in the Laboratory
Penetration of graded asphalt
Flash point and fire point using Cleveland open cup.
Softening point using ring & ball apparatus.
