Asphalt joints are inevitable parts of every pavement. They are
constructed for different reasons. Although much attention is dedicated to the
construction joints (hot with hot pavement), a scientific approach for cold
joints (cold with hot pavement) with respect to large patch constructions is
still missing. This report tries to evaluate existing construction techniques and
to suggest new testing methods of tests. Although, indirect tensile tests IDT
and direct tension tests DTT are familiar in the field of asphalt pavement
characterization, they have not been used for the assessment of joint quality so
far. In this report, these two test types are evaluated and the results are
analyzed using finite element software ABAQUS. The results of the
comparison of joint compaction techniques on a laboratory scale suggest that
joints with angles seem to show more promising behavior than vertical joints.
Also, starting compaction from the hot side generally produces better results
than compaction starting from cold side.
