Utilização do ensaio de flexão sobre amostra semicircular para avaliação da propagação do trincamento em misturas com diferentes ligantes

Abstract: Neste trabalho é estudada a propagação de fissuras e ruptura em misturas asfálticas através do ensaio de flexão semicircular. Trincamentos que surgem nos revestimentos asfálticos revelam-se como um dos principais danos que afetam diretamente a serventia e qualidade dos pavimentos flexíveis. Esta pesquisa busca contribuir para a análise da resistência ao trincamento, bem como propagação do trincamento até a ruptura de misturas asfálticas onde são utilizados três diferentes tipos de ligantes. Para este fim empre… Show more

“…The displacement rate was adopted based on the rates used by Godoi et al ( 12 ), Minhajuddin et al ( 28 ), and Saha and Biligiri ( 29 ). The stopping criterion was the same used by Godoi et al ( 12 ), and it is still the criterion recommended by the AASHTO standard TP 124/2016. Testing results were recorded with a data acquisition system and used to plot the load versus load point displacement (LPD) curve.…”

“…In relation to the study of fracture resistance of HMA under different conditions, different experimental tests have been developed. Among existing tests, the semicircular bending (SCB) test has become very popular to investigate asphalt concrete fracture resistance, and can be found in many references (10)(11)(12)(13)(14)(15)(16)(17), among several others). In general, studies on HMA highlight the advantage of the SCB fracture test because of its simplicity, speed, and low cost involved in the overall testing procedure.…”
