Evaluation of Antistripping Additives

Report No: 90-R4

Published in 1989

About the report:

Several chemical antistripping additives were used in field installations and compared to a similar installation using hydrated lime. The performance of the installations was monitored periodically, and material that was sampled during construction was tested in the laboratory. The cores of mixes with less visual stripping showed a gradual increase in strength and stiffness with time, whereas mixes with considerable stripping showed little, if any, increase. Two additives influenced the viscosity of the asphalt significantly, thereby requiring the lowering of the required mixing and compaction temperatures.
