由于对恢复现有道路的需求不断增长，减少预算资金以及增加环境问题，沥青回收和回收是一种巨大的增长。

Recycling of Reclaimed Asphalt Pavement (RAP) is the process of recovering aged asphalt and wrapping it around reclaimed asphalt aggregates. RAP can also be incorporated into energy-saving warm-mix asphalt (WMA) technologies. These technologies allow asphalt pavements to be produced at lower temperatures, meaning reduced energy demands and lower emissions during production and paving. WMA additives also serve in a compaction aid capacity allowing for improved densities to be achieved.

Aging and hardening of asphalt binder happens when the binder is exposed to heat, light, and air. In order to restore the properties of aged asphalt, it’s necessary that the old pavement be reclaimed and recycled. Asphalt pavement is the most widely recycled product in the U.S. According tothe latest surveyby the National Asphalt Pavement Association, more than 71.9 million tons of RAP were put to use in new pavements in the U.S. during the 2014 construction season (a 30% increase from 2009), saving taxpayers more than $2.8 billion. Also, about a third of all asphalt pavement mixture produced in that year was made using WMA technologies.

沥青回收的好处包括：重用和保护不可再生的自然资源，保护环境和降低土地填充，节能，施工工程区的交通安全，现有道路几何形状的保存，对路面矫正的矫正，改进路面平滑度，改进的路面物理性质，以及一些方法缓解或消除开裂

Care should be taken when selecting roadways and rehabilitation methods. Pavements that have fundamental shortcomings and deficiencies are not eligible for many recycling methods. The Pavement Consulting Group at Braun Intertec has the knowledge and experience in evaluating existing pavements and selecting the appropriate recycling strategy to meet the owner’s needs.
