ASPHALT REPAIR

ASPHALT REPAIRS: If you have potholes, alligatoring, or other failing pavement areas, RDU Paving, Inc. can repair these areas for you. Or perhaps you are simply interested in maintaining the quality of your existing pavement through Sealcoating, PDC (Pavement Dressing Conditioner), Asphalt Rejuvenator, Full-Depth Reclamation (FDR), or Line Striping. Unlike other companies, we offer a 1 year warranty on sealcoating and a 3 year warranty on our PDC (Pavement Dressing Conditioner). An estimator will meet with you at your site to determine the best cost-effective and long-term solution for your property. We can handle all of your pavement repair needs from fixing simple potholes to solving a more complex problem such as drainage, erosion, or subgrade issues. We are experienced paving professionals capable of handling any size project.

RDU Paving Provides the Following Asphalt Pavement Repairs:

Umstead Hotel - Patching Raleigh, NCASPHALT PATCHING/POTHOLE REPAIRS: Asphalt Repair is often a cost-effective appropriate solution to isolate pavement areas that have failed. Areas that have potholes or are severely alligatored are obvious pavement failures that require cutting, debris removal, and replacement with full-depth asphalt. Asphalt Patching provides strength to the existing pavement structure by replacing the failed pavement with a solid base. Depending on the size of the failing pavement area, we may be able to easily fill or fix your pothole, or we may have to repair a larger area of damaged pavement for the best results. Our estimators evaluate pavement defects on a case-by-case basis by and match them to the most appropriate solution. 

Be cautious of contractors that recommend simply overlaying the damaged areas with new asphalt. In a short time period, the previous cracked areas will show up in the new asphalt as reflective cracking. If your budget is a concern, we will work with you to provide a plan that will result in the best value and long-term solution for you. Combining patching with Sealcoating, PDC, or Rejuvenator and then planning for an overlay in a few years is a much better solution than simply overlaying the existing damaged asphalt.


Radisson Hotel - Overlay ServicesASPHALT RESURFACING: As asphalt ages, it begins to gray and develop hairline cracks, alligator-like areas, or potholes. If this is too extensive, asphalt patching alone may not be a practical solution. Some patching may be necessary along with bituminous surface treatment (BST) to stabilize the area. Finally, an asphalt overlay can be placed. The final result is a smooth, black surface. We combine the optimum asphalt mix along with the best rolling techniques to achieve an aesthetically pleasing product. Overlaying the existing asphalt with new asphalt should be completed approximately every 10 years or when the aggregate becomes exposed. Sealcoating or PDC Rejuvenator should be applied in the meantime in order to slow the oxidation and drying out process. Customers should be leery of contractors that simply propose an overlay a pavement repair solution. Most paving repair projects require more complex solutions. If an overlay is placed without any prep or asphalt repair, you can expect reflective cracking to appear through the new pavement.


Full-Depth Reclamation - RDU PavingFULL-DEPTH RECLAMATION: Full-depth reclamation is a recycling technique that reuses the underlying materials and incorporates an additive such as cement before regrading, compacting, and paving the site. Full-Depth Reclamation may be the most cost effective and best long-term solution when a parking lot has severely deteriorated, and typical pavement repair techniques such as patching or overlay will not hold up. FDR may also make sense when more than 40% of the areas will require full depth patching. FDR is a good candidate when: base or subgrade failure issues are present, severe rutting or deep depressions exist, or repeated patching failures occur. See our Full-Depth Reclamation page for more information.

The FDR Process: 1) The existing old asphalt and base material is pulverized in place to a specified depth usually between 8” and 12”. 2) An additive such as cement is introduced to the mixture and distributed among the material. 3) Water may be added depending on the nature of the existing soils. 4) The existing material and cement are again pulverized and blended with the reclaimer machine. 5) The modified base is graded and compacted to proper depth and elevation in preparation for paving. 6) New pavement is installed immediately after the site has cured.


Church - Sealcoating for Parking Lot

SEALCOATING: Raveling or hairline cracking can occur in the pavement as part of the aging process or from stress. Sealcoating can often be the solution to this problem, but it is best performed in the first 5 years of the pavement life. Ideally, sealcoating should be completed after 2 years of pavement life and reapplied every 2 years. If the pavement is structurally sound with no visible alligatored areas, sealcoating will help extend the life of the pavement. The surface is also restored to a black surface which gives the asphalt a “new” look. Our sealcoating material meets or exceeds federal specifications, and we always apply 2 coats of material as recommended by the manufacturers. We also utilize a pre-mixed Coal-Tar product, so our product is never watered down. With these high standards, we are able to provide a 1 year warranty on our sealcoating.


Columns at Wakefield - Pavement Dressing ConditionerPAVEMENT DRESSING CONDITIONER (PDC) or ASPHALT REJUVENATOR: We offer PDC as a superior alternative to sealcoating. Pavement Dressing Conditioner (PDC) or Asphalt Rejuvenator is a product that actually penetrates the pavement up to 3/8″ after application. PDC restores the viscosity and extends the life of the pavement. Curing may take as long as 30 days. The life expectancy of the PDC is often 4-5 years, and the PDC has a 3 year warranty. PDC is a NCDOT approved product and can be submitted for approval on City of Raleigh & NCDOT streets. Please click the following link to view the detail. NCDOT Vendor Approved Product 

Also, PDC results in a non-skid surface, so you won’t hear the tire squealing like you will with sealcoating. PDC is a superior product to coal tar sealcoating and is used on airport runways, race tracks, and even at Disney World. Please contact us to learn more about this product or to visit some sites in your area. PDC should be applied after 2 years of pavement life and reapplied every 4-5 years.


Tryon Village - Patching & Crack FillingCRACK FILLING: Hot pour crack fillers are used to repair cracks in the pavement. Crack Filling will adhere to the cracked area and seal it, preventing moisture from penetrating the area and causing further damage. Preparation for Crack Filling includes cleaning the areas in order to ensure that the sealer adheres properly to the area. Crack filling should be completed on cracks larger than 1/8″. Crack filling is not recommended in badly deteriorated asphalt areas. Extremely damaged areas of asphalt need to be removed and replaced rather than crack filled and sealed.
