| Abstract | The bituminous sealants used in the preventive maintenance of pavements sometimes deform (track) under the action of passing vehicles. In summer, this is the prevalent mode of sealant failure. To assess the propensity of a sealant to deform in summer a standard flow test is used, but the imprecision in the results have prevented any correlation with field performance. In an attempt to find an alternative means of assessing deformation, two methods were evaluated. The first method relied on the use of the French rut tester, whereas the second method relied on the use of a Taber abraser. The first method was found to be inappropriate to test sealants because of its severity, but the second method proved promising. The Taber abraser allowed for the measurement of sealant displacement at various temperatures, and for distinguishing the deformation propensity of sealants. |
