Supplementary Notes Research performed in cooperation with the Texas Department of Transportation and the U.S. Department of Transportation, Federal Highway Administration. Research Project Title: Evaluation of Pavement Marking Effectiveness 16. Abstract This report describes the tasks of research conducted to identify effective pavement marking practices for sealcoat and hot-mix asphalt (HMAC) pavements in Texas. The researchers reviewed literature, determined current Texas Department of Transportation (TxDOT) and alternative pavement marking practices, and evaluated various pavement marking treatments in the field. The researchers identified few shortcomings related to pavement marking practices on HMAC pavement surfaces. However, for sealcoat pavement surfaces, numerous opportunities for improving pavement marking quality were identified. Based on the research findings, numerous recommendations were developed, which pertain to thermoplastic application on sealcoat and HMAC, waterbased paint application on sealcoat, sealcoat aggregates, surface glass beads, and field inspection.

  • Chipseal Road Surfacing
    Chipseal Overview Muskegon County Chipseal surface treatment is one of the 2 largest projects that MCRC conducts during 7700 East Apple Avenue • Muskegon • MI • 49442 the year. Chipseal treatments are typically Road Commission done in the early summer months when conditions are optimal. Chipseal Road Surfacing Chipsealing is a process used for pavement preservation and rehabilitation, in which, an asphalt emulsion is placed on a prepared roadway, and immediately thereafter, an aggregate (loose stone) is applied to the roadway, which is compacted to create a revitalized road surface. By comparison to other road surface treatments, chipseal is one of the most economical, and long-lasting options available to MCRC. Service Requests To file a service request, MCRC can be contacted either at our office or by telephone, and your request will be forwarded to the appropriate department; Phone: 231.788.2381 (Press 1) Fax: 231.788.5793 Chipseal Benefits Construction Process Conditions Chip seals are used for restoring skid resistance, Construction Sequence protecting a surface from aging, restoring a running The sequence of construction events is as follows: Chipseal Treatments are typically conducted during surface, eliminating dust, and sealing gravel 1.

See reverse side for a map of each location. Every year the City’s Street Maintenance Division determines which city streets would benefit the most from a chip sealing treatment to extend the asphalt’s service life. Many factors go into this determination, such as asphalt and sub-base condition. Chip sealing involves Street Location applying layer of asphalt oil sealant and then covering it with a layer of small “chip” rock.

  • What Is Chip Seal? Why Do We Use Chip Seal on County Roads? My
    What is Chip Seal? Chip Seal is a pavement surface treatment that is also known as Tar and Stone, Oil and Stone, or Bituminous Surface Treatment. Preservation of Investment is the largest reason Highway Departments utilize this method. The process uses two materials, a liquid asphalt binder (the “tar” or “oil”) and a stone aggregate. A Chip Seal’s purpose is to “seal” the road from water penetrating which can shorten the life span of the road. Any repairs needed to the roadway system are made prior to beginning the Chip Seal process. In most cases, Chip Seals are applied to roads that have recently been repaired and the County is working to preserve the investment and extend the life. Once the road is prepped and ready the binder is applied directly to the existing pavement surface. Immediately following the binder the stone aggregate is applied uniformly across the pavement surface. Large roller equipment follows and compacts the aggregate into the binder. Once the road is reopened to traffic the vehicles driving over the new Chip Seal will continue to embed the stone deeper into the binder providing a more stable traveling surface. After several days/weeks of travel have occurred a road sweeper is used to clean up any remaining loose stone and the new road surface is painted with roadway striping. Why do we use Chip Seal on County roads? Chip Seal is a very cost effective means of Pavement Preservation. It typically costs one fourth to one fifth the cost of a conventional asphalt overlay. Chip Seals can extend the life of a roadway by 5-7 years as well as correct pavement conditions such as surface bleeding (where liquid asphalt leeches out of the pavement), variations to surface texture, raveling (disintegration of pavement due to loss of aggregate), cracks, decreased skid resistance, etc.
