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。

回收沥青路面（RAP）的回收是回收老化沥青并在回收的沥青聚集体周围包裹物的过程。RAP也可以纳入节能的温混合沥青（WMA）技术。这些技术允许在较低温度下产生沥青路面，这意味着在生产和铺路期间减少能源需求和降低排放。WMA添加剂还用于压实助剂能力，允许实现改进的密度。

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.
