Abstract
This report is based on the four tests which were carried out on the laboratory to
help gain concepts in Highway Engineering. Highway Engineering being a broad area
of study involves the study of both foundation of the subbase and the design of the
pavement surfaces. These two areas of study were involved in the laboratory
experiments which were carried out.
The experimental work involved tests on bitumen and tests involving the California
Bearing Ratio. The test on bitumen are carried out prior the design of the
pavements so as to know the important parameters affecting the pavement. Pavement
are always exposed to adverse environmental condition among them being temperature.
In the experiments carried out on bitumen; softening point, the needle penetration
test and the viscosity of cutback bitumen test, it was observed that temperature
and affected the softening point and also the fluidity of bitumen.
On the soil test, various experiment were carried out on the sample soil among them
being the compaction test, the % moisture content test, the swelling and the CBR
test. The maximum dry density of the soil and its corresponding optimum moisture
content were achieved. Through computations, the recorded penetrations and their
corresponding forces in the CBR test helped in getting the CBR at 2,5 and 5.0 mm
where the highest value were considered. The experiments carried out were compared
to the expected results where no much discripancy were observed
