3.3.5 Extreme Stress Seal (XSS)

An extreme stress seal (XSS) is used to accommodate extreme stresses imposed by heavy traffic volumes and high proportions of heavy vehicles, or difficult service conditions such as long climbing lanes or tight radius curves. An XSS is a double/double seal where the bituminous binder is a medium to heavily modified PMB.
