Description

Lafarge Asphalt is committed to being the leading developer and supplier in North America of innovative asphalt products designed to optimize quality, performance, durability, and sustainability.

Durawhisper™ hot mix asphalt uses crumb rubber to modify the asphalt cement binder to provide a thin asphalt overlay specifically designed to reduce noise.

Technical Benefits of Durawhisper™
Reduces tire noise
Provides improved resistance to surface-initiated cracking and improved resistance to fatigue and reflection cracking
Improves rutting resistance
Results in reduced life-cycle costing and lower pavement maintenance costs



Durawhisper™ consists of a 10mm nominal size, dense-graded asphalt mixture designed with 2 to 4 percent air voids. The aggregate particle shape and the design of the stone skeleton provide excellent rutting resistance and vehicular traffic noise-reducing characteristics. Crumb rubber, which is added to the asphalt mix, is beneficial for improved durability and long-term performance, particularly when subject to heavy slow-moving traffic.

The combination of the crumb rubber additive and the use of a polymer-modified binder provide increased resistance to reflective cracking initiated when paving overlays to existing concrete slabs.

Its traffic noise-reducing properties make Durawhisper ideal for surfacing in and around subdivisions and general residential areas.
