A Brittle Point Test for Low Temperature Studies of Bitumens
In order to study the low temperature performance of asphalts, improvements have been made for determining the brittle point of bituminous materials. A new procedure for preparing the coated plaques is proposed which enables a film of asphalt of known thickness to be prepared. The apparatus has been mechanized and the spring steel plaque replaced with a clear polyvester film. The brittle point unit is cooled at any desired rate using alcohol as the coolant. Studies have been made of effect of film thickness and rate of cooling upon the brittle point temperature. Study of the effect of overheating a dead-level roofing asphalt is shown to be one of the uses of the instrument. (Author)
