Abstract [en]

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.
