Cracking Resistance of Asphalts: Phoenix Test
Cracks in asphalt pavements are one of the most frequent causes of deterioration. Due to the rheological characteristics of the asphalt mixtures make your cracking behavior is complex to analyzeThis is because it depends on several factors that make the material behave in a completely different way to the stresses produced by the environment and the traffic, than the ones produced by the environment and the traffic. are manifested by thermal variations and different types and speeds of load application.
The Phoenix Essay es un laboratory procedure which consists of submit half test tube cylindrical asphalt mix to a direct tensile stress in order to assess the cracking resistance of asphalt mixes.This allows for the possibility of considering variables such as asphalt mix type and composition, temperature and the effects of aging on the road during its service life. An effective methodology for the quality control or testing of materials.
How to interpret the results obtained in the Fenix Assay?
From the recorded load-displacement curve during the performance of the test, the various defined parameters are calculatedaccording to the expressions, which can be related to the mechanical and strength characteristics of the material test mixture.
As a result of the test, the average value of the values obtained when testing the different semi-cylindrical specimens is obtained for each parameter. It is normally sufficient to test 3 to 4 specimens. If the difference between the individual values and the mean is greater than 2.5 times the standard deviation of the repeatability, the results will be analyzed in order to assess if there is any anomalous result, which will not be taken into account, or new additional specimens will be tested.
