Pavement preservation reduces the amount of pavements requiring corrective or emergency maintenance, resurfacing, major rehabilitation, and reconstruction, but it does not completely eliminate the need for these other strategies. Typical pavement …Maintenance treatments covered in this handbook include: Crack repair wisealing, including clean and seal, saw and seal, and rout and seal; crack filling, full depth crack repair, fog seal, seal coat, double chip seal, slurry seal, microsurfacing, thin hot mix overlays, and potholes and pavement patching.

Maine Asphalt Pavement Association Care and Maintenance of your new Driveway • It's important to realize that asphalt takes a minimum of 2 years to fully cure, or harden. that time there are some things that you, as a homeowner, can do to preserve the appearance of your new driveway.of the pavement. This will seal off the avenues for water to get into the pavements base and affect adjacent areas of the pavement. As you can see when any form of maintenance is performed it has a positive effect on the life of the pavement and the future of the system as a whole.

ASPHALT PAVEMENT MAINTENANCE, FOURTH EDITION A GUIDE TO OPTIMIZING THE PAVEMENT LIFE CYCLE THROUGH QUALITY/TIMELY PAVEMENT MAINTENANCE PRACTICES Initially Prepared by W.J. Pijl, Headquarters Technician, Paving Branch, Ministry of Transportation & Highways Victoria, B.C. February, 1985formance perspective. Recycled asphalt pavement (RAP) shows promise at reducing natural resource consumption and construction energy requirements. While reducing heat and increasing use of recycled asphalt are obvious tech-niques to make asphalt pavement more sustainable, the quantification of their benefits and impact on service life are unknown.
Revised April 2007 Chapter 7 Pavement Maintenance • Frost Protection Layer - provides a barrier against frost action and frost penetration into the lower frost-susceptible layers. • Subgrade - Compacted soil layer which forms the foundation for the pavement system. Subgrade soils are subjected to lower stresses than the surface and subbase courses.Patching may be done on an asphalt pavement either for maintenance purposes or rehabilitation purposes. Maintenance patching is expedient and temporary repair, sometimes done in cold weather, with cold-mixed patching mixtures, and without careful construction procedures. As a result, maintenance patches generally do not exhibit the same long-term
water in pavement layers and the subgrade. One approach to lowering the cost of repairing a pavement is to apply a thin asphalt overlay as a Pavement Preservation treatment before more expensive treatments are needed. If a stronger intervention is needed then maintenance and rehabilitation options need to be identified suitable for the distresses.Preventive Maintenance and Pavement Preservation A preventive maintenance program is a systematic approach to using a series of preventive maintenance treatments over time. One treatment will improve the quality of the pavement surface and extend the pavement life, but the true benefits of pavement maintenance are realized when there is a

The Asphalt Pavement Technology Program is an integrated, national effort to improve the long-term performance and cost effectiveness of asphalt pavements. Managed by the Federal Highway Administration through partnerships with State highway agencies, Industry and academia the program's primary goals are to reduce congestion, improve safety, andpavements. A.01 Definitions . Maintenance of asphalt pavement covers the repair of both surface and base of the roadbed between State right of way lines. It includes public road approaches and city street intersections within State right of way. Maintenance work can be defined as work performed to preserve the riding qualities, safety
FAA Advisory Circular 150/5380-6, Guidelines and Procedures for Maintenance of Airport Pavements Strategic Highway Research Program SHRP-P-338, SHRP-H-349 & SHRP-H-348 Asphalt Institute, Manual Series No. 16, Asphalt in Pavement Maintenance Copies of these references are available from the City Engineer or the Airport Manager.Asphalt pavement is a flexible pavement allowing it to withstand occasional over-loads without serious damage. Its resistance to freeze-thaw and deicing salts provides for superior performance during inclement weather. Its lack of repetitive joints removes the possibility of the blowups that
The Asphalt Pavement Association of Oregon is a non-profit trade association representing contractors and associated firms. APAO was formed in 1969 by a small group of asphalt paving contractors to develop improved specifications and products. The Association and its members are dedicated to promoting asphalt pavements by developing pro-ASPHALT AND CONCRETE PAVEMENT MAINTENANCE AND REPAIR .
