13. ABSTRACT (Maximum 200 words)
A pavement joint seal prevents the passage of liquids into the pavement base and the intrusion of solids into the
joint. The primary mechanical requirements of a pavement seal are that it respond elastically or viscoelastically
to any movement of the joint without failure and that it withstand indentation of hard objects like rocks. Be-
cause pavement joint movements and seal deformations can be large, elastomeric sealants are often used to
form seals. Winter conditions are recognized as the most critical for a seal because of the possibility that failure
stresses will be reached as the joint opens to a maximum and the material stiffens in response to the temperature
reduction. This report reviews the specific problems and requirements that cold climates create for the perfor-
mance of elastomeric seals. Emphasis is placed on the material response behavior that can lead to failure of a
seal. In an attempt to clarify the mechanics of sealant and seal performance associated with low-temperature
pavement applications and to address the issue of low-temperature stiffening that should be a dominant factor
in the selection of a sealant, this report presents background information on the formulation and mechanical
properties of elastomeric seal materials and the structural behavior of field-molded joint and crack seals.
