Bonded Pavement Technology for Stronger Asphalt Overlays
What is Bonded Pavement Technology?
Bonded pavement technology is designed to create a strong bond between an existing pavement surface and a new hot mix asphalt (HMA) overlay, allowing the pavement layers to perform as a single structural system. Arkema's BondTekk® bonded pavement technology improves adhesion between pavement lifts, helping reduce premature cracking, improve durability, and extend pavement service life.
Traditional paving methods often rely on applying a thin tack coat ahead of the paving operation. As construction equipment travels across the surface, much of the tack coat can be displaced before the asphalt overlay is placed, resulting in reduced bonding between pavement layers and increasing the risk of premature pavement failure.
How Bonded Pavement Technology Improves Performance
Creating a Stronger Bond Between Pavement Layers
Traditional paving methods often rely on applying a thin tack coat before paving. Construction traffic can remove much of this tack coat before the overlay is placed, resulting in reduced bonding between pavement layers and increasing the risk of premature pavement failure.
Improving Overlay Durability
By maintaining a stronger bond between pavement lifts, bonded pavement technology improves structural performance while reducing cracking, moisture infiltration, and long-term deterioration.
Supporting Longer Pavement Life
A stronger bond between pavement layers helps extend pavement service life while reducing roadway maintenance costs and minimizing disruptions to motorists.
Arkema's BondTekk® Technology
BondTekk® is Arkema's advanced bonded pavement technology designed to maximize the bond between existing pavement surfaces and new hot mix asphalt overlays.
Using a spray paver, BondTekk® enables agencies and contractors to apply a high-performance polymer-modified tack coat at application rates four to six times greater than traditional paving methods. Because the tack coat is applied immediately before the asphalt mix is placed, construction traffic does not track or remove the material, resulting in significantly improved bond strength.
The increased application rate not only creates a stronger bond between pavement layers but also forms a stress-absorbing membrane that helps delay cracking in the new asphalt overlay.
BondTekk® has been successfully used on both concrete pavements and existing hot mix asphalt surfaces, delivering longer-lasting pavements with improved durability and reduced maintenance requirements.
Arkema supports customers with laboratory testing, pavement design expertise, and field technical support to help optimize bonded pavement performance for a wide range of roadway applications.
