      <title>EFFECTS OF MOISTURE ON SURFACE CHEMISTRY OF STEEL SLAGS AND STEEL SLAG-ASPHALT PAVING MIXES</title>
      <link>https://trid.trb.org/View/452574</link>
      <description><![CDATA[Random cracking and premature failure have been observed in some steel slag-asphalt pavements in Ontario.  The causes of the failure were investigated.  Surface chemistry and morpholoty of steel slags and asphalt mixes and the effect of moisture on these characteristics were studied using scanning electron microscopy, scanning electron microscopy coupled with energy-dispersive s-ray analysis, and optical microscopy.  X-ray diffraction and electron microprobe analysis were used for mineralogical studies.  Experiments were also performed to determine moisture uptake and volume expansivity of steel slags and steel slag-asphalt mixes.  Basic oxygen furnace slags and an electric arc furnace slag were used in this investigation, and asphalt mixes were prepared from some samples.  The results indicate that failure in steel slag-asphalt mixes in moist environments is due to the formation of calcium-rich deposits, mainly calcium carbonate, along the surface and the interface. This affects interfacial bonding and can cause excessive expansion of the slag leading to cracking of the mixture.  This reactivity was also observed in field core samples, even after several years of service.  The mineralogical data showed that the distribution and microstructure of the two main phases (an iron oxide-rich mixed oxide phase and a calcium silicate phase in steel slags) were different among the slags examined.  The calcium silicate phase appears to be one of the sources responsible for the reactivity of steel slags in moist environments.]]></description>

      <title>FLOW MICROCALORIMETRY AND SALI STUDIES OF THE ASPHALT/AGGREGATE INTERFACE. IN: AMERICAN CHEMICAL SOCIETY SYMPOSIUM ON CHEMISTRY AND CHARACTERIZATION OF ASPHALTS, AUGUST 1990, WASHINGTON, D.C.</title>
      <link>https://trid.trb.org/View/371143</link>
      <description><![CDATA[Sorption flow microcalorimetry methods were developed for measuring the amounts and heats of adsorption and desorption at the asphalt-aggregate interface. Model studies of the amounts and heats of phenylsulfoxide sorption on SHRP aggregates RH-greywacke and RC-McAdams limestone indicated strong and irreversible bonding of a large fraction of adsorbed phenylsulfoxide that resisted displacement by cyclohexane and water. In addition, the microcalorimetry results indicated that intermolecular interactions between adsorbed phenylsulfoxide molecules were very strong at submonolayer coverages. This suggests that phenylsulfoxide adsorbs with the sulfoxide directly attached and oriented perpendicular to the surface with strong face-to-face interactions of the phenyl groups. Similar experiments conducted on the sorption of SHRP asphalts AAD-1 and AAM-1 from solution on the RC and RH aggregates indicated significant differences in the sorption of these four asphalt-aggregate pairs. Surface analysis by laser ionization (SALI) was used to measure surface compositions of the aggregates and to monitor temperature programmed desorption (TPD) of adsorbed phenylsulfoxide. SALI analysis indicated that a significant fraction of the RC aggregate is covered with an aluminosilicate layer although bulk analysis indicates that this aggregate is predominantly limestone. TPD studies confirmed the microcalorimetry results that a large fraction of phenylsulfoxide irreversibly binds to silicate and aggregate surfaces and moreover that this irreversible binding leads to deoxygenation of the sulfoxide to sulfide at relatively low temperatures.]]></description>

      <title>SURFACE CHARACTERIZATION OF REINFORCING STEEL AND THE INTERACTION OF STEEL WITH INHIBITORS IN PORE SOLUTION</title>
      <link>https://trid.trb.org/View/364831</link>
      <description><![CDATA[Studies of rebar surfaces following cleaning in various ways and following exposure to corrosive solutions in the presence and absence of inhibitors have been carried out using the surface-sensitive technique:  x-ray photoelectron spectroscopy (XPS).  After cleaning in hexane, rebar specimens were exposed to simulated pore solution with or without corrosion inhibitors under specified conditions. Subsequent XPS analysis of the rebar specimens indicated that the corrosion inhibitors sodium nitrite, sodium molybdate, sodium dihydrogen phosphate, sodium monofluorophoshate, and sodium tetraborate produced changes in rebar surface chemistry that could be associated with corrosion inhibition.  The principal changes were (a) alteration in surface iron content, (b) reduction in the surface hydroxide concentration, and (c) increase in surface oxide oxygen concentration.  The results are interpreted to indicate that these inhibitors promote the formation of surface oxides at the expense of hydroxide functionality. Results from the study of sodium tetraborate reveal that this inhibitor produces a coating on the rebar surface.]]></description>

      <description><![CDATA[Electron spectroscopy (esca) and optoacoustic spectroscopy (oas) have been used to study the surfaces of commercial ordinary and white portland cements.  The surfaces have reduced cation and increased oxygen contents compared with the bulk material.  Surface hydroxyl groups can be detected in slightly different forms on the two cements.  The results are compared with those from the pure synthetic cement minerals.  (TRRL)]]></description>

      <title>SAMPLE BIAS IN TELEPHONE INTERVIEW TRAVEL SURVEYS</title>
      <link>https://trid.trb.org/View/272368</link>
      <description><![CDATA[The methodological aspects of travel surveys have been subjected to much recent investigation, with a major emphasis being placed on the biases inherent in a variety of survey instruments.  This paper examines the bias in one particular type of survey, the travel survey conducted by telephone interview.  More specifically it examines the bias created by the omission of non-telephone households from the sample, but does not address the bias in responses received over the phone.  The study is conducted by examining the characteristics of phone-owning households in the 1978/79 Melbourne home interview survey.  In this way, a sample is created which approximates that which would have been obtained had the interview been conducted by telephone. The characteristics of phone-owning and non-phone-owning households are compared with respect to socio-economic characteristics, and areas of potential bias in the survey results are identified.  The study then examines differences in travel patterns and suggests ways in which such biases may be corected.  (Author/TRRL)]]></description>

      <title>SURVEY OF MOTORIST ROUTE-SELECTION CRITERIA (ABRIDGMENT)</title>
      <link>https://trid.trb.org/View/73603</link>
      <description><![CDATA[A sample of commuters in the central business district of Dallas was given a questionaire about their choice of routes to and from work, the reasons for their choice, their reasons for selecting or not selecting an alternate route in the event of delay, and how advance information would have influenced their decisions.  A sample of drivers was also interviewed at rest stops on an Interstate leading to Houston and were asked about the route they planned to take, why they chose it over alternatives, how they would react to information about a delay, and what advance information was desired about a route; a mail-in questionaire asked similar questions about their actual past experience when confronted with a traffic jam.  Route selection criteria (i.e. speed, directness, convenience) were fairly consistent suggesting that a message system providing traffic information and positive route could satisfy the needs of a majority of drivers.  Many of those who had or would have elected to remain on a congested route did so out of lack of information about the extent of delay and about alternate routes and would have diverted if they had had additional information.  It is concluded that real-time signing and the radio can provide the information drivers need and that the public should be made aware that the information these provide is timely and creditable so that drivers can make better route selection decisions.]]></description>

      <description><![CDATA[The applications and roles of display monitors are reviewed, the basic functional types are identified, the selection of a monitor is discussed, and comments are made on the questions that must be considered in the use of such monitors.  The scanning Auger microprobe (for analyzing the chemistry and electrical conductivity of small surfaces) and the gamma camera (acts like an x-ray) are described as examples of widely differing applications for display monitors.  A special application is the kineisograph which monitors the position and movement of a dental patients jaw, displaying the data on a CRT graph form.  It is also used in the video tape recorder.  The two basic functional types of monitors are: nonstorage; and storage-bistable and variable persistence storage monitors.  Basic questions are listed that must be answered in selecting a display monitor.]]></description>

      <title>MECHANICAL BEHAVIOR OF ASPHALT-MINERAL POWDER COMPOSITES AND ASPHALT-MINERAL INTERACTION</title>
      <link>https://trid.trb.org/View/98292</link>
      <description><![CDATA[THE EXTENT AND NATURE OF THE INTERFACIAL INTERACTION BETWEEN MINERAL AGGREGATE AND BITUMEN WAS STUDIED. AN INDIRECT APPROACH WAS TAKEN BY CHOOSING A SYSTEM WHEREIN A VARYING AMOUNT OF SURFACE AREA COULD BE GENERATED. SEVERAL WELL-DEFINED MINERAL POWDERS OF DIFFERING SIZE WERE ADDED TO TWO DIFFERENT BITUMENS. THE STRESS-STRAIN BEHAVIOR OF THESE COMPOSITES WAS THEN DETERMINED AND COMPARED FOR EVIDENCE OF INTERFACIAL INTERACTION. THE POWDERS WERE MIXED WITH TWO DIFFERENT ASPHALT CEMENTS (AC-20 GRADE) USING A SPECIALLY DESIGNED VACUUM MIXING APPARATUS. THE VACUUM MIXING WAS NECESSARY TO ACHIEVE AN HOMOGENOUS, AIR-FREE MIXTURE. TO DETERMINE THE STRESS-STRAIN RELATION FOR VARIOUS COMPOSITES AND UNFILLED ASPHALTS, THE SAMPLE TO BE TESTED WAS MOUNTED AS A PAIR OF THIN DISKS SANDWICHED BETWEEN THREE STEEL PLATES. A DYNAMIC OR STATIC SHEAR STRESS WAS THEN IMPARTED TO THE SAMPLE BY SHEARING THE CENTER PLATE WITH RESPECT TO THE TWO OUTER PLATES. TESTS WERE PERFORMED AT 5, 15, AND 25 C AND AT FREQUENCIES FROM 0.053 TO 50.3 HZ AND UP TO 120 SECONDS IN CREEP. THE TESTING WAS LIMITED TO LINEAR BEHAVIOR. LINEAR VISCOELASTIC BEHAVIOR WAS VERIFIED IN THE DYNAMIC MEASUREMENTS BY THE INDEPENDENCE OF COMPLIANCE ON STRESS LEVEL AND BY THE SINUSOIDAL RESPONSE TO A SINUSOIDAL INPUT. NO THIXOTROPIC EFFECT WAS NOTICED: STEADY STATE RESPONSE (DYNAMIC) WAS ATTAINED AFTER ONLY A FEW CYCLES. LINEAR VISCOELASTIC BEHAVIOR IN CREEP WAS VERIFIED BY THE INDEPENDENCE OF COMPLIANCE ON STRESS LEVEL AND BY THE ADDITIVITY OF STRESS HISTORY. WITH THE ESTABLISHED LINEAR VISCOELASTIC CHARACTERISTIC USED AS A MEDIUM OF COMPARISON, THE MINERALS WERE FOUND TO INTERACT WITH THE ASPHALT IN A DEGREE VARYING WITH POWDER SIZE AND TYPE AND THE ASPHALT TYPE. /AUTHOR/]]></description>
