The Right Treatment, to the Right Pavement, at the Right Time!
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.
Products for Pavement Preservation
Dust Suppression Ideal Application Dirt roads Dust sensitive areas Life Cycle (Years) 1 to 2
Fog Seal Ideal Application Dust Suppression Surface Oxidation Life Cycle (Years) 1 to 2
Single/Double Chip Seal Ideal Application Low to Med Traffic Volume roads Life Cycle (Years) 3 to 5
Chip Seal Variations Single Chip Seals Existing Pavement Pneumatic- Tired Roller Binder
Chip Seal Variations Double Chip Seals Existing Pavement Binder Pneumatic- Tired Roller Second Binder Application Pneumatic- Tired Roller
Micro Surfacing Ideal Application Town/City streets Highways Parking 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
Products for Re-Construction
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 roads Estate 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 –Mixing Blade Laid Dump, Spread and Compact
Emulsion Mix –Paver Lay-down No Fumes Time To Work with Product Simple Operation
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 Lots Streets Life Cycle (Years) 12 to 14

Typical Problems Standard Solutions
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
