Entrained Air-Void System For Durable Highway Concrete

In the US, the most commonly used F-T test method is AASHTO T 161 "A." The equipment for variant A of the test is relatively low cost ($̃22, 000) and compact. The relatively low cost stems from the basic construction of a refrigerant-based cooling system and resistive heating elements. These units are easily repaired by conventionally trained heating and air conditioning
