Asphalt is 100% recyclable
Building better roads can come with substantial cost savings and environmental stewardship. How? By using reclaimed asphalt pavement (RAP) in road construction and rehabilitation.
Why RAP Max™ works for you
Husky Asphalt has developed a specialized product that allows road builders to take their RAP design from 20% to 38% and still meet specification. That gives them significant cost savings while delivering quality roads for owners and drivers.

How much RAP is too much RAP?
RAP mix designs have been used across North America since the 1970s.
Allowable spec RAP content percentages have risen with technological advancements:
- in 2008 the U.S. national average was 12%
- by 2013, the percentage increased to just under 20%
With new advances, Husky Asphalt aims to raise the specification to higher percentages, maximizing customer savings and environmental benefit.
What is Recycled Asphalt Pavement?
The Asphalt Institute defines RAP as: “Excavated asphalt pavement that has been pulverized, usually by milling, and is used like an aggregate in the recycling of asphalt pavements.”
Pavement recycling treatments
The Pavement Preservation and Recycling Alliance (PPRA) lists several different types of recycling treatments, including:
- hot in-place recycling (HIR)
- cold in-place recycling (CIR)
- cold central plant recycling (CCPR)
- full depth reclamation (FDR)
No road barriers to recycling
From road owners to road builders, everyone wants to ensure top quality pavement.
Test after test, using RAP in road building and rehabilitation has met specifications set by the American Association of State Highway and Transportation Officials (AASHTO) and government transportation agencies.
The PPRA suggests RAP can enhance road performance with better strength, impermeability and flexibility.
More than just structural advantages
When compared to the traditional removal and replacement process, recycling pavement offers many benefits:
- lower construction costs
- increased road life cycle
- environmental stewardship
- faster time to finish
Lower construction costs
Rubblizing and reusing asphalt pavement on-site means massive cost savings for road builders. Experts estimate cost savings between 20-50% from reduced transportation, time and materials.
Increased life cycle
British Columbia's Ministry of Transportation and Infrastructure (MoTI) boasts a 25-year success story using hot in-place recycling (HIR) to effectively double the service life of its roads.
The PPRA offers compelling sample data showing a recycling-first approach can add between seven and 25 years of pavement life.
The PPRA estimates between 80,000,000 and 100,000,000 tons of RAP are milled off U.S. roads each year. Reusing asphalt is good for the environment, plain and simple.
- reduces energy consumption
- reduces greenhouse gas emissions
- reduces amount of transportation required
- conserves natural resources
Faster time to finish
In-place recycling can reduce or even eliminate time for trucking and hauling of construction materials. Many RAP treatments can be opened to traffic immediately upon completion. You save time and money, and the travelling public can get back on the road faster.
