| Abstract: | Traditional test method of air void system by ASTM C457 is too complicated,time-consuming and subjective,so three new excellent automatic test methods of air void system including AVA,RapidAir and image analysis system are introduced and analyzed in detail in this paper.Their test results are consisted with the ASTM C457 very well and they are more convenient and accurate to test the air void system with the instruments of AVA、RapidAir and by the image analysis system.These methods should be made more widespread on the measurement of the air void system. |
