Metric Plan Reading Course, HR-324, 1997

This Plan Reading Course was developed by the Department of Civil and Construction Engineering of Iowa State University under contract with the Iowa Highway Research Board, Project HR-324. It is intended to be an instructional tool for Iowa DOT, county and municipal employees within the state of Iowa. Under this contract, a previous Plan Reading Course, prepared for the Iowa State Highway Commission in 1965, has been completely revised using a new format, new plans, updated specifications, and new material. This course is a self-taught course consisting of two parts; Highway Plans, and Bridge and Culvert plans. Each part consists of a self-instruction book, a set of plans, a question booklet, and an answer booklet. This is the self-instruction book for the Bridge and Culvert Plans part of the course. The example structures included in this part of the course are a prestressed concrete beam bridge and a reinforced concrete box culvert.

Plan Reading Course, HR-324

This booklet is part of the Bridge Plan Reading Course developed by the Department of Civil and Construction Engineering of Iowa State University under contract with the Highway Research Advisory Board, Project HR-324. It is intended to be an instructional tool for Iowa DOT and county and municipal employees within the state of Iowa. The questions in this booklet are designed to test your knowledge of the material in the Bridge Plan Reading Course. You are free to use both the plans and the text material to assist you in answering these questions. There is a separate ANSWER BOOKLET which contains the answers to these questions. Consult that booklet to make sure you have answered these questions correctly. If you miss the answer to a question, go back and review the text material and the plans to make sure you understand the correct answer.

Incentive-Disincentive Clause, HR-521, 1985

There is an urgent need to complete projects in high traffic urban areas in the shortest possible time. These road user benefits resulting from faster construction will minimize public inconvenience, safety hazards and a total cost to the public. The incentive - disincentive clause in the contract will encourage the contractor to expedite all phases in the contract. A copy of this special provision is part of this work plan and other details of construction are included in the plan and specification of Project F-65-4(34)--20-77.

Low Profile Marker for Wet/Night Visibility, HR-1005, 1977

Conventional highway lane markings are ineffective at night, particularly when the pavement is wet. There is a recognized need for a system that is effective at night under wet conditions and where there is no reduction in current daytime standards. To be effective at all times the system must maintain wet-night retroreflective properties while resisting deterioration caused by snowplows, studded tires, sand and salt applications, and lane changing maneuvers by traffic. This project tested a system of low-profile lane markers developed by Battelle Columbus Laboratory under contract with the Implementation Division of the Federal Highway Administration.

Asphalt Emulsions for Highway Construction (Emulsion Seal Coat), HR-1028, 1980

For the past several year Kossuth County has had a scheduled maintenance program of bituminous seal coating. This program has been used to maintain the 467 miles of asphaltic concrete surfaced roads in Kossuth County. Since most of the experience that Kossuth County had in seal coating was with cutback asphalt, it was decided to include the use of emulsified asphalt in Kossuth County's 1980 seal coat program. Federal Demonstration Project Funds were requested from the Federal Highway Administration to study the use of emulsified asphalt and funding was granted under Demonstration Project No. 55,:Asphalt Emulsions for Highway Construction." Items studied were design and construction procedure cost of alternate material, energy consumption and environmental considerations. A construction contract was awarded to Everds Brothers, Inc. of Algona, Iowa, on July 1, 1980. There were four bidders on the 54.5 miles of seal coating that was let. A map showing the location of the seal coating projects is shown in Appendix A, and a copy of the contract is shown in Appendix B. The contractor started the project on July 11, 1980 and completed the project on August 1, 1980. Construction inspection and follow-up inspections of the project were conducted by personnel of the Kossuth County Engineer's Office and testing of the materials, friction testing and road rater testing were conducted by the Material's Department of the Iowa Department of Transportation.

Epoxy Thermoplastic Traffic Marking Material, HR-1033, 1982

This Implementation Package summarizes the result of an effort to develop a more durable traffic marking material-Epoxy Thermoplastic (ETP). The report includes background information on the development of ETP, a discussion of the field tests and evaluations, the material composition and equipment modifications for applying ETP. The package also includes material specifications for purchasing ETP and specifications for the application of ETP by contract.

Evaluation of Deicing Materials and Corrosion Reducing Treatments for Deicing Salts, TR-471, 2007

Effective winter maintenance makes use of freezing-point-depressant chemicals (also known as ice-control products) to prevent the formation of the bond between snow and ice and the highway pavement. In performing such winter maintenance, the selection of appropriate ice-control products for the bond prevention task involves consideration of a number of factors, as indicated in Nixon and Williams (2001). The factors are in essence performance measurements of the ice-control products, and as such can be easily incorporated into a specification document to allow for selection of the best ice-control products for a given agency to use in its winter maintenance activities. Once performance measures for de-icing or anti-icing chemicals have been specified, this allows the creation of a quality control program for the acceptance of those chemicals. This study presents a series of performance measurement tests for ice-control products, and discusses the role that they can play in such a quality control program. Some tests are simple and rapid enough that they can be performed on every load of icecontrol products received, while for others, a sampling technique must be used. An appropriate sampling technique is presented. Further, each test is categorized as to whether it should be applied to every load of ice-control products or on a sampling basis. The study includes a detailed literature review that considers the performance of ice-control products in three areas: temperature related performance, product consistency, and negative side effects. The negative side effects are further broken down into three areas, namely operational side effects (such as chemical slipperiness), environmental side effects, and infrastructural side effects (such as corrosion of vehicles and damage to concrete). The review indicated that in the area of side effects the field performance of ice-control products is currently so difficult to model in the laboratory that no particular specification tests can be recommended at this time. A study of the impact of ice-control products on concrete was performed by Professor Wang of Iowa State University as a sub-contract to this study, and has been presented to the Iowa Highway Research Board prior to this report.

State of Iowa Employee Handbook, 2015

This information is based on Iowa Department of Administrative Services (DAS) rules and policies and does not create an employment contract. Much of the information in this handbook is also covered in the State’s collective bargaining agreements. Where there are differences between a collective bargaining agreement and this handbook, the collective bargaining agreement prevails for employees covered by the agreement. Where there are differences between this handbook and DAS rules and policies, DAS rules and policies prevail.

05008-004 Mill-Picayune (Manteno Lake) Watershed Final Report

Manteno Lake is located 8 miles northwest of Earling, IA in Shelby County. The lake has been impaired with an overload of silt and nutrients. In October of 2007, land directly north of the lake will be coming out of CRP and back into agricultural production. The Shelby Soil and Water Conservation District, Shelby County Board of Supervisors and Shelby County Conservation Board feel strongly that treatment of this area is necessary prior to the CRP contract expiring. The placement and construction of three structures will reduce the amount of silt and nutrients affecting Manteno Lake. This project calls for the construction of three structures on crucial tributaries to the lake.
