Mit Hilfe von theoretischen und experimentellen Untersuchungen werden neben der Verbundwirkung an den Schichtgrenzen und dem Ermüdungsverhalten, die Tragfähigkeit und das Verformungsverhalten der Bauweise Asphaltzwischenschicht unter Betonfahrbahnen (AZSuB) geprüft. Darauf aufbauend werden tiefergreifende Anforderungen an die Bauweise AZSuB definiert, um die Bauweise AZSuB hinsichtlich Dauerhaftigkeit und Wirtschaftlichkeit weiterzuentwickeln., The composite effect at the layer boundaries, the fatigue behavior, the load-bearing capacity and the deformation behavior of the construction method of asphalt intermediate layer underneath concrete pavement (AZSuB) have been tested. Based on these results more profound requirements have been defined for the AZSuB construction method in order to develop the AZSuB construction method further to improve durability and economic efficiency.

Introduction: Due to potentially severe sequelae (impaired growth, condylar resorption, and ankylosis) early diagnosis of chronic rheumatic arthritis of the temporomandibular joint (TMJ) and timely onset of therapy are essential. Aim: Owing to very limited evidence the aim of the study was to identify and discuss controversial topics in the guideline development to promote further focused research. Methods: Through a systematic literature search, 394 out of 3771 publications were included in a German interdisciplinary guideline draft. Two workgroups (1: oral and maxillofacial surgery, 2: interdisciplinary) voted on 77 recommendations/statements, in 2 independent anonymized and blinded consensus phases (Delphi process). Results: The voting results were relatively homogenous, except for a greater proportion of abstentions amongst the interdisciplinary group (p < 0.001). Eighty four percent of recommendations/statements were approved in the first round, 89% with strong consensus. Fourteen recommendations/statements (18.2%) required a prolonged consensus phase and further discussion. Discussion: Contrast-enhanced MRI was confirmed as the method of choice for the diagnosis of TMJ arthritis. Intraarticular corticosteroid injection is to be limited to therapy refractory cases and single injection only. In adults, alloplastic joint replacement is preferable to autologous replacement. In children/adolescents, autologous reconstruction may be performed lacking viable alternatives. Alloplastic options are currently still considered experimental.
