Sprinkle Treatment of Asphalt Pavements, MLR-78-01, 1978

The paper reviews methods, materials, equipment and results to date of sprinkle treatment within the state. The Iowa Department of Transportation formerly the Iowa State Highway Commission, made its first attempts at sprinkle treatment of fresh asphalt concrete in 1974. Increased emphasis in mix design of asphalt mixes and aggregate selection of durable non-polishing materials has generated costly restrictions on the use of local materials. During the summer of 1975, a dual spinner, tail-gate spreader was mounted on a standard departmental dump truck to attempt additional sprinkle treatment on a section of Iowa 7 west of Ft. Dodge. The dump truck equipment was marginally satisfactory, but results of increased surface skid texture and durability were well demonstrated. On 1976 a new, current order dump truck was modified with an auxiliary transmission and a set of slick surfaced tires, and dual spinner spreader was mounted to again attempt surface sprinkle treatment, which was conducted in 1977.

Iowa Drainage Laws (Annotated), HR-46 and Iowa Highway Research Board Bulletin No. 6, 1957

In the preparation of this compilation of drainage laws of Iowa, an attempt has been made to include those sections of the Code to which reference is frequently required by the State Highway Commission, Boards of Supervisors and County Engineers in the conduct of highway and road administration as it is affected by the Iowa drainage laws. Of necessity some Code provisions which have a bearing on the principal subject were omitted. Enactments of the 56th General Assembly which modify existing code sections have been included as part of the regular text of the Code sections included in this publication. THE USER IS CAUTIONED THAT THESE CODE SECTIONS, AS MODIFIED BY THE 56th GENERAL ASSEMBLY, ARE NOT A PART OF THE 1954 CODE OF IOWA AND ARE OFFICIAL ONLY INSOFAR AS THEY ARE PRINTED IN THE OFFICIAL PUBLICATION ACTS OF THE 56TH GENERAL ASSEMBLY. SINCE THE 57TH GENERAL ASSEMBLY IS IN SESSION DURING THE PRINTING OF THIS PUBLICATION, ENACTMENTS OF THAT BODY WHICH AMEND OR REPEAL SECTIONS SET OUT HEREIN ARE INCLUDED IN THE BACK OF THIS VOLUME ON THE PINK-COLORED PAPER. THE USER IS CAUTIONED IN USING THIS VOLUME TO REFER TO THE TABLE OF SECTIONS REPEALED OR AMENDED, ON THE PINK-COLORED PAPER AT THE BACK OF THIS VOLUME. This publication is offered with the hope and belief that it will prove to be of value and assistance to those concerned with the problems of administering a highway, road and drainage system.

Report on Rest Area Water Systems for Interstate Highways, 1967

Introduction: As part of the roadside development along the Interstate Highway System, the Iowa State Highway Commission has constructed eight pair of rest area facilities. Furthermore, two pair are presently under construction with an additional two pair proposed for letting in 1967. An additional nine and one-half pairs of rest areas are in the planning phase, a grand total of 45 rest Brea buildings. The facilities existing were planned and designed in a relatively short period of time. The rest area facilities are unusual in terms of water use, water demand rates, and the fact that there are no applicable guidelines from previous installations. Such facilities are a pioneering effort to furnish a service -which the travelling public desires and will use. The acceptance and current use of the existing facilities shows that the rest areas do provide a service the public will use and appreciate. The Iowa State Highway Commission is to be congratulated for this· pioneering effort. However there are problems, as should be expected when design of a new type of facility has no past operating experience to use as a guide. Another factor which enters is that a rest area facility is quite different and rather unrelated to engineering in the highway field of practice. Basically, the problems encountered can be resolved into several areas, namely 1) maintenance problems in equipment due to 2) insufficient capacity of several other elements of the water systems, and 3) no provisions for water quality control. This study and report is supposed to essentially cover the review of the rest areas, either existing and under construction or letting. However, the approach used has been somewhat different. Several basic economically feasible water system schemes have been developed which are· adaptable to the different well capacities and different water qualities encountered. These basic designs are used as a guide in recommending modifications to the existing rest area water systems, anticipating that the basic designs will be used for future facilities. The magnitude of the problems involved is shown by the fact that the projected water use and demand variations of each rest area building is equivalent to the water supply for a community of about 100 people. The problems of proper operation and maintenance of an eventual thirty to forty-five such facilities are gigantic. For successful operation the rest area water systems must have a high degree of standardization and interchangeability of all elements of the water systems, even if it means a limited degree of over-design in some rest area facilities.

A Continuous Span Aluminum Girder Concrete Deck Bridge - Part 2 of 2: Fatigue Tests of Aluminum Girders, Final Report, 1997

In 1957, the Iowa State Highway Commission, with financial assistance from the aluminum industry, constructed a 220-ft (67-m) long, four-span continuous, aluminum girder bridge to carry traffic on Clive Road (86th Street) over Interstate 80 near Des Moines, Iowa. The bridge had four, welded I-shape girders that were fabricated in pairs with welded diaphragms between an exterior and an interior girder. The interior diaphragms between the girder pairs were bolted to girder brackets. A composite, reinforced concrete deck served as the roadway surface. The bridge, which had performed successfully for about 35 years of service, was removed in the fall of 1993 to make way for an interchange at the same location. Prior to the bridge demolition, load tests were conducted to monitor girder and diaphragm bending strains and deflections in the northern end span. Fatigue testing of the aluminum girders that were removed from the end spans were conducted by applying constant-amplitude, cyclic loads. These tests established the fatigue strength of an existing, welded, flange-splice detail and added, welded, flange-cover plates and horizontal web plate attachment details. This part, Part 2, of the final report focuses on the fatigue tests of the aluminum girder sections that were removed from the bridge and on the analysis of the experimental data to establish the fatigue strength of full-size specimens. Seventeen fatigue fractures that were classified as Category E weld details developed in the seven girder test specimens. Linear regression analyses of the fatigue test results established both nominal and experimental stress-range versus load cycle relationships (SN curves) for the fatigue strength of fillet-welded connections. The nominal strength SN curve obtained by this research essentially matched the SN curve for Category E aluminum weldments given in the AASHTO LRFD specifications. All of the Category E fatigue fractures that developed in the girder test specimens satisfied the allowable SN relationship specified by the fatigue provisions of the Aluminum Association. The lower-bound strength line that was set at two standard deviations below the least squares regression line through the fatigue fracture data points related well with the Aluminum Association SN curve. The results from the experimental tests of this research have provided additional information regarding behavioral characteristics of full-size, aluminum members and have confirmed that aluminum has the strength properties needed for highway bridge girders.

Estudo da concentração de material particulado em ambientes internos e externos de bibliotecas

Our twenty-first century society and the rhythm of life and work we have to face in our daily routine compel us to spend most of our lifetime in closed environments, in our houses, educational institutions, hospitals, airports, amongst as many others. The study of the air quality in internal environments (IAQ) is very important for monitoring people’s health effects and their environmental comfort in these locations. One essential parameter to analyze this measure is to evaluate the concentration of dispersed particulates in the air, specially focusing on those thinner particles (below the diameter of 2,5 μm), they can pose serious risks for human being because they can remain in the lungs, penetrate through the pores of our skin, amongst other harmful effects on human’s health. In this work the air quality inside the public library Profª Josina Vasques Ferrari and at Unesp public state library was evaluated, both located in Itapeva, as well as a third one, inside the Communitarian Library of the Federal University in Carlos (UFSCar) from march to may in 2012. In those environments it was analyzed if the concentration of particulates pose any real treat to the users. The equipment used for particle sampling in real time was DataRam 4 (Model DR 4000). The results given for those concentrations of particulates in both internal and external environments revealed figures within the safe standard established by the WHO (World Health Organization), from 25 to μg/m³, the only exception occurred on the fifth floor of the UFSCar library, where the average for concentration stayed at 25,30 of μg/m³

Medidas de controle da circulação do livro didático para o ensino de leitura e escrita em São Paulo: atuação da commissão revisora de 1918

In order to contribute to the understanding of the history of the teaching of reading and writing and the history of political movement of textbooks in Sao Paulo, Brazil, we present the results of the analysis of the documents produced by the Review Commission Textbook, established in 1918 by the General Board of Education of São Paulo State. This commission aimed to review which books among the already approved by previous committees, should continue as recommended for use in elementary schools in São Paulo. For this, the commission has prepared various reports, which are representative of the actions of the state government to control the circulation and use of textbooks in elementary schools in the early twentieth century.
