Pavement Preservation
• Allows you to change your approach:
– Look for and correct small problems before they become big ones
– Eliminate the "worst first" Practice
Pavement Preservation
• Pavement Preservation is efficient, effective and economical.
• Save money• Improve safety• Reduce delays• Help pavement last longer• Improve the performance of the entire road network
Doing It Right!
The Right Pavement
• Relying on public complaints is to probably to late.
• Up to date pavement condition surveys are key
Doing It Right!
The Right Time
• Preventative Maintenance needs to be completed in the early stages of the pavement’s Life.
• Move preventative maintenance up on the priority list.
Doing It Right!
The Right Treatment
• Picking the proper treatment for the right level of distress. Here are some things to consider:
Doing It Right!
• The type of pavement• The type, extent and severity of the pavement distress• The age of the pavement (or the time since the last
major rehabilitation)• The type of the road - its use, volume, and traffic speed• The availability of qualified contractors, construction
technology; materials and qualified agency staff• The time of year for maintenance• How long maintenance will take and the impact it will
have on drivers• The pavement quality needed after the pavement has
been treated.
Single/Double Chip Seal
Ideal Application
• Low to Med Traffic Volume roads
Life Cycle (Years)3 to 5
Micro Surfacing
Ideal Application
Town/City streetsHighwaysParking lot caps
Life Cycle (Years)7 to 8
HMA Thin Lifts (Polymer or standard)
Ideal Application
• High volume roads• Intersections• Distressed
pavement application
Life Cycle (Years)8 to 10
Double Chip Seal
Ideal Application
• Low to Med volume streets
• Secondary or connector routes
Life Cycle (Years)5 to 7
Cape Seal
Ideal Application
Low to Med volume roadsEstate or subdivisions streets
Life Cycle (Years)7 to 8
Emulsion Mix (Central Plant)
Ideal Application
• Logistically challenging areas
• Areas where conventional equipment not available
• Roads needing full or partial reclamation
Life Cycle (Years)8 to 10
Emulsion Mix – Central Plant Mixing
Simple Operation, Quick Set up, Long Shelf Life (weeks) vs hours for Hot Mix
Emulsion Mix
• Pavement provides excellent strength and logistics flexibility where traditional hot mix asphalt is too expensive.
• Utilize locally available aggregate or RAP• Reduce haul rates
Hot Mix Asphalt(Standard or Polymer Modified)
Ideal Application
High volume roads,Parking LotsStreets
Life Cycle (Years)12 to 14
Types of Treatments/Typical Costs
Treatments Costs $/M2
Fog seals 1.25
Chip seals 4.00
Micro surfacing 7.40
Emulsion Mix 10.00
Thin hot mix overlays 14.75
*Prices accurate at time of presentation, prices vary depending on conditions of work.
Cracking
• Cause:– Asphalt Shrinkage, Cold
Temperatures, Shifting Underlaying
• Solution:– Crack Sealant– And / Or followed by Chip
Seal, Slurry or other surface
– Partial or full depth reclamation
Rutting
• Causes:– Traffic and Heat– Weak Subgrade– Mix Type
• Solutions– Microsurfacing
for minor rutting– Milling– Polymer Asphalt
for busy intersections
Ravelling
• Causes:– Aging Pavement– Low Compaction /
Placed late in season– Sub-base Issue– Segregated Un-Even
Mixtures• Solutions:
– Fog Seal– Chip Seals– Microsurfacing– Slurry Seals– Emulsion Mix
Complete Failure
• Causes:-Lack of
Maintenance
-Poor sub grade
-Under designed
• Solutions:-Mill Back to Gravel
-Full-Depth Recycling
