PAVEMENT EVALUATION
Degree of Compaction
Mass of sample in water
Mass of sample in saturated dry
Mass of sample in air
Bulk density
d=MOSIA/(MOSISD-MOSIW)
DOC=S.G core(site)/ S.G material(lab)* 100%
Compare
Bitumen Content
mass of filtering, W2
mass of filtering + filter, W3
mass of sample, W1
extracted sample, W4
Extraction Test
To separate bitumen content and aggregate
Detail measurement of mass before and after record
To determine Bitumen content
Filtering is used in test
Aggregate Distribution
