Deformation and tracking of bituminous sealants in summer temperatures: pseudo-field behaviour
Bituminous sealants used for road maintenance sometimes fail due to the excessive deformation or flow under the shearing action of tires in summer temperatures. To better understand this failure mode, a small-scale tracking test was developed and applied to twenty-one sealants held at temperatures between 46°C and 82°C - typical pavement temperatures in North America. The sealant flow characteristics acquired from the testing provide the basis for developing a performance-based method for identifying sealants with good resistance to shearing action.
