Jackson County is comprised of 607 square miles, of which approximately 240 square miles are unincorporated. County forces maintain approximately 470 miles of roads, of which about 90 percent are composed of oiled earth and the accumulation of years of chip and seal treatments. An additional two percent of the County roads are untreated gravel. Cou

This report covers the design and testing of a hot mix recycling process. The process involved the removal of existing pavement by the cold planing process and production of the hot mix recycled paving mixture utilizing a portion of the salvaged material. The mix was produced by the heat transfer method of production. The field testing includes con

A whole array of existing breakaway luminaire supports were tested using the FHWA soft-nosed pendulum test device. The pendulum was developed to simulate a subcompact car behavior. This nose was properly validated against full- scale test data. Due to unacceptable impact performance, modifications were made to cast aluminum transformer bases to red

"The work presented in this report represents a preliminary effort to integrate economic factors with the physics of highway drainage. Conventional culvert design rests on the selection of a flood peak flow having a particular return period; for example, the flood flow expected to occur once in a hundred-year period. A culvert is designed to pass t

This manual represents the state-of-the-art for the design of urban highway drainage. Historical practice has involved a philosophy of intersecting, collecting, and disposing of stormwater runoff as rapidly as possible. The cumulative effects of such past concepts of urban storm drainage have been a principal cause of increased frequency of downstr

The module of programs supplied for a State to use in preparing their HPMS data submittal tape will develop the database from cards or card images, edit the section data, correct errors in the data, and develop mileage, DVMT, and volume group summaries by functional class. The module consists of a main (calling) program, STHPMS, and four subprogram

During the past several years, much attention has been directed toward the acceptable removal of obsolete pavement markings. There are a number of methods available for marking removal including chemical paint removers, sandblasting, high pressure water jet, grinding, hydroblasting and high temperature burning. Most of these methods have been used

The objective of the symposium was to acquaint the engineering and construction professionals with the current state-of-the-art of this rapidly growing bridge concept in order to assess future thought, study, development, and practice. Although initial contemporary design and construction have predominantly occurred in Europe, currently there are c

The Highway Performance Monitoring System (HPMS) will provide the Federal Highway Administration (FHWA) with the capability to (I) periodically assess the extent and condition of the highway systems and (2) monitor the performance of the highway systems on a continuing basis. Performance will be monitored through the assessment of the extent and ph
