Full Depth Reclamation: When applicable, partial or full-depth reclamation (FDR) is used as
<br />a cost and time-saving alternative to traditional reconstruction. Associated costs include
<br />replacement of striping and pavement markings, adjustment of manholes, and other work
<br />needed to return the street to normal operation.
<br />Crack Seal: Placing specialized materials into cracks in unique configurations to keep water
<br />and other matter out of the crack and the underlying pavement layers. Crack sealing can be
<br />used for two different reasons in pavement maintenance. One is a treatment to seal the cracks
<br />in order to prevent moisture intrusion into the pavement. The other is preparatory work for
<br />other treatments, such as overlays, and slurry seals.
<br />Reclaimed Asphalt Pavement (RAP):The term given to removed and/or reprocessed
<br />pavement materials containing asphalt and aggregates. These materials are generated when
<br />asphalt pavements are removed for reconstruction, resurfacing, or to obtain access to buried
<br />utilities. When properly crushed and screened, RAP consists of high-quality, well-graded
<br />aggregates coated by asphalt cement that can be reused as a substitute for a portion of virgin
<br />materials in asphalt and aggregate base.
<br />Recycled Asphalt Shingles (RAS):A primary reason for the high potential value of recycled
<br />shingles is that they contain ingredients that hot mix asphalt (HMA) producers purchase to
<br />Asphalt shingles also contain a fibrous mat made from organic felt (cellulose) or fiberglass that
<br />can also be valuable as fiber in some asphalt paving mixes.
<br />Current Treatment Costs
<br />This chart (Fig.3) provides detail of the current cost for treatment of the entire improved system
<br />excluding concrete streets at the end of the 2018rating period. The total estimated treatment cost
<br />backlog at the end of 2018 is $68.4million down from $79.8million reportedin 2017.
