  • A Study of Occurrence of Potholes and Washboards on Soil-Aggregate Roads EUGENE Y
    A Study of Occurrence of Potholes and Washboards on Soil-Aggregate Roads EUGENE Y. HUANG, Associate Professor of Civil Engineering, University of Illinois This report presents the results of a study aimed at determining some of the circumstances associated with the occurrence of potholes and washboards on soil-aggregate roads. The study consisted of a statistical analysis of the qualitative data obtained from a road condition survey involving road surfaces of the coarse-graded aggregate type composed of mineral aggregate such as gravel or crushed stone and some binder material. Results of the study indicate that the occurrence of potholes and washboards was definitely associated with the volume of traffic, the type of surface material, and the drainage condition of the road surface. Although the findings are admittedly limited to the types and conditions of the roads studied, it is hoped that the data may be of value in further understanding the formation of potholes and washboards. • THE OCCURRENCE of potholes and washboards has long been a serious problem in soil-aggregate surfaces. These formations, however, have not been fully explained. Potholes on road surfaces are irregularly occurring, well-defined holes consisting of fairly deep cavities up to about 5 in. (Fig. 1). Washboards are transverse or nearly transverse waves on road surfaces, generally about 1 to 1/4 in. in amplitude andspaced about 2 or 3 ft apart (Fig. 2), regardless of the nature of material in which they occur. (Although typical formations of potholes and washboards are readily distinguishable, there are, however, numerous possibilities of transitional forms between these two typical forms.) Both potholes and washboards are conducive to surface impact and vibration, which contribute in a great measure to the rapid deterioration of the road surface as well as the vehicle itself.

Introduction The Cornell Local Roads Program Center provides training, technical assistance, and information to municipal officials and employees responsible for the maintenance, construction, and management of local highways and bridges in New York State. This educational service has been widely used throughout New York State by many municipalities who wish to run their highway departments more effectively and efficiently. Part of the Cornell Local Roads Program (CLRP) is a cost analysis tool developed by Civil Engineers from Cornell University. The purpose of this tool is to generate a road database for prioritizing and recommending various repairs objectively. The basis of the program is to collect road condition data and catalog a detailed list of information through software known as the Cornell Asset Management Program ­ Roads & Streets (CAMP­RS). CAMP­RS functions chiefly by “Keeping good roads good” and consistently improving the conditions of subpar roads within the constraints of a limited budget. CAMP­RS outputs a prioritized list of repairs in order to efficiently raise the condition of all roads to an acceptable level.

  • Johnson Survey Comments
    5. Please share any other comments or concerns you have about the johnson Road Full Improvements Project. Response I favor the three lane option with one very la rge drainage pipe (along with other utilities) beneath 1. the center (turn) lane. Seems to me that such an arrangement might facilitate maintenance without ~ Respons~ the necessity of closing down the whole road. I don't understand how pedestrians are able too safely cross the roundabout. I don't see it planned here and I watched the presentation and didn't hear it addressed.

  • Bumpy Road Ahead: AMERICA’S ROUGHEST RIDES and STRATEGIES to MAKE OUR ROADS SMOOTHER
    Bumpy Road Ahead: AMERICA’S ROUGHEST RIDES AND STRATEGIES TO MAKE OUR ROADS SMOOTHER OCTOBER 2018 TRIPNET.ORG Founded in 1971, TRIP ® of Washington, DC, is a nonprofit organization that researches, evaluates and distributes economic and technical data on surface transportation issues. TRIP is sponsored by insurance companies, equipment manufacturers, distributors and suppliers; businesses involved in highway and transit engineering and construction; labor unions; and organizations concerned with efficient and safe surface transportation. EXECUTIVE SUMMARY: KEY FACTS ABOUT OUR NATION’S URBAN ROADS Keeping the wheel steady on America's roads and highways has become increasingly challenging as drivers encounter potholes and pavement deterioration. One-third of the nation’s major urban roadways – highways and major streets that are the main routes for commuters and commerce – are in poor condition. These critical links in the nation’s transportation system carry 70 percent of the approximately 3.2 trillion miles driven annually in America. Road conditions could deteriorate even further as the rate of vehicle travel continues to increase and local and state governments find they are unable to adequately fund road repairs. In this report, TRIP examines the condition of the nation’s major roads, including pavement condition data for America’s most populous urban areas, recent trends in travel, the latest developments in repairing roads and building them to last longer, and the funding levels needed to adequately address America’s deteriorated roadways. For the purposes of this report, an urban area includes the major city in a region and its neighboring or surrounding suburban areas. Pavement condition data are the latest available and are derived from the Federal Highway Administration's (FHWA) 2016 annual survey of state transportation officials on the condition of major state and locally maintained roads and highways, based on a uniform pavement rating index.

  • How Are Pothole Claims Handled?
    How Are Pothole Claims Handled? City streets have taken a beating these past years. Heavy rains, freezing temperatures, ice and snow have taken their toll. The resulting potholes and defects are usually considered road hazards. They are not due to negligence on the part of the City. Springfield Development and Public Works (DPW) uses a complaint driven system to address road defects such as potholes. DPW relies on reports from the public to locate road defects. Call the DPW operations division at 541-726-3761 to report potholes. Based on reports from the public, DPW will prioritize needed repairs. Is it a pothole? Potholes form when rainwater sinks through cracks in old or weakened asphalt. The water saturates the road’s aggregate base. Vehicles passing over the road force fine particles of the roadbed up and out of cracks in the asphalt (called pumping). Loss of fine particles from the aggregate base result in voids. These voids cause the aggregate base and the asphalt layer to sink. As the as asphalt sinks it eventually cracks under the continued impact of vehicle tires and chunks come loose. A sinkhole is a hole that reaches past the base of the roadway. Sinkholes are generally larger and deeper than potholes. They are usually caused by a source of water under the pavement, such as a broken pipe. The water causes the soil to wash away, creating a void under the pavement, and eventually the pavement gives away. Delaminations are formed when the upper asphalt concrete layer becomes detached and breaks apart from the underlying layer.

SUPPLEMENTARY NOTES 16. ABSTRACT California Department of Transportation (Caltrans) maintenance crews repaired approximately 75,000 potholes from 2012-2013. Widely disbursed over 50,000 lane miles of highway, these potholes in most cases rendered conventional lane closures for safe access impractical. Instead, maintenance crews were typically resigned to capitalize on breaks in traffic to rapidly go out and place cold patch asphalt into a pothole and quickly retreat. After the deaths of two Caltrans workers who were patching potholes in 2006-2007, Caltrans tasked the Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center with developing a safer and more efficient means of patching potholes.
