Chloride Penetration Into LSDC (Iowa System) Resurfacing Mixes, MLR-77-05 and R-267, 1977

The purpose of this investigation was to determine the comparative effectiveness of standard D-57 concrete and Iowa system Low Slump Dense Concrete in preventing threshold levels of chloride from penetrating the concrete slabs to the reinforcing steel.

Use of Reagent Grade Versus Industrial Grade Trichlorethylene in Asphalt Recoveries, MLR-83-05, 1983

This is a continuation of a project initiated a year ago to determine any differences in test results on recovered asphalt cements caused by the use of industrial grade of solvent as compared with the reagent grade. AASHTO specifies the use of reagent grade of trichlorethylene, but the Laboratory uses industrial grade which costs much less. Last year this objective of the project was aborted when it was found that a larger difference in test results was obtained between the two distillation apparatuses than between the two solvents, Then all efforts were directed toward obtaining uniformity in test results between the apparatuses under the east hood as compared with that under the west hood. Considerable progress was made toward this end. (See report under this same title dated April 1982). The objective this year was to again evaluate the results when using both variables (apparatuses and solvents). Another objective developed later in this investigation; this was to determine any differences in test results on recovered asphalt cements caused by the use of reclaimed trichlorethylene (from the distillation process) as compared with the use of industrial grade of solvent. At the present time the reclaimed trichlorethylene is discarded. If the reclaimed solvent could be used for further recoveries, a considerable savings in solvent costs would result.

Sieve Analysis of Combined Aggregate Samples by Different Test Methods, MLR-84-05, 1982

This past winter the sieve analysis of combined aggregate was investigated. This study was given No. 26 by the Central Laboratory. The purpose of this work was to try and develop a sieve analysis procedure for combined aggregate which is less time consuming and has the same accuracy as the method described in I.M. 304. In an attempt to use a variety of aggregates for this investigation, a request was made to each District Materials Office to obtain at least 3 different combined aggregate samples in their respective districts. At the same time it was also requested that the field technician test these samples, prior to submitting them to the Central Laboratory. The field technician was instructed to test each sample as described in method I.M. 304 and also by a modified AASHTO T27 method which will be identified in the report as Method A. The modified AASHTO Method A was identical to T27 with the exception that a smaller sample is used for testing. The field technicians submitted the samples, test results and also comments regarding the modified AASHTO procedure. The general comments of the modified AASHTO procedure were: The method was much simpler to follow; however, it took about the same amount of time so there was no real advantage. After reviewing AASHTO T27, T164, I.M. 304 and Report No. FHWA-RD-77-53 another test method was purposed. Report No. FHWA-RD-77-53 is a report prepared by FHWA from data they gathered concerning control practices and shortcut or alternative test methods for aggregate gradation. A second test method was developed which also was very similar to AASHTO T27, The test procedure for this method is attached and is identified as Method B. The following is a summary of test results submitted by the Field Technicians and obtained by the aggregate section of the Central Laboratory.

Les grands dirigeants du sport : 23 portraits et stratégies de management.

Le sport doit beaucoup aux dirigeants qui construisent les conditions de développement des organisations sportives (création de structure, d'événements, de modèles économiques, de nouvelles logiques de fonctionnement...). Leur univers est plus caché et moins connu que celui des très grands champions... et pourtant leur influence est déterminante pour le sport et son avenir. Cet ouvrage analyse les parcours, les pratiques de management et l'héritage de 23 grands dirigeants du sport de différentes époques (du début du XXe siècle à aujourd'hui) et de différents univers sportifs (olympisme, sport professionnel, événementiel, industrie du sport...). Comment Juan Antonio Samaranch, Jacques Rogge, Annie Courtade, Jean-Michel Aulas, Serge Blanco, Philippe Chatrier, Joseph S. Blatter, Bernie Ecclestone, Thierry Sabine, Richard Peddy... ont géré leurs parcours ? Quelles ont été les stratégies et les pratiques de management suivies ? Quelles décisions majeures ont-ils prises et pourquoi ? Finalement, quel héritage ont-ils ou laissent-ils à leur organisation et pour leur sport ? Des experts de différents pays analysent et décortiquent ici ces éléments passionnants des coulisses du sport. Cet ouvrage s'adresse aussi bien aux experts et étudiants en gestion d'entreprise et en gestion du sport, aux dirigeants sportifs qu'au grand public.
