      <title>WET SIZING OF AGGREGATES</title>
      <link>https://trid.trb.org/View/107030</link>
      <description><![CDATA[THE USUAL METHOD OF SCREENING AGGREGATES IN MOIST CONDITION IS UNSATISFACTORY IN MANY RESPECTS. IN PARTICULAR, THE SEPARATION OF FINE AGGREGATES INTO DIFFERENT SIZE FRACTIONS AND THE TOTAL REMOVAL OF DELETORIOUS FINE-GRAINED SUBSTANCES OFTEN CONSTITUTE THE NECESSARY CONDITIONS WHICH MUST BE FULFILLED IN ORDER TO OBTAIN A GOOD HOMOGENEOUS COMPOSITION OF THE AGGREGATES. WET SCREENING USED IN COMBINATION WITH HYDRAULIC METHODS OF SEPARATION AFFORDS A VALUABLE POSSIBILITY IN THIS CONNECTION. DURING THE CONSTRUCTION OF THE OSSAUSKOSKI HYDRO-ELECTRIC POWER STATION, SUCH METHODS OF SIZING AGGREGATES FOR CONCRETE WERE EMPLOYED FOR THE FIRST TIME IN FINLAND. IN SPITE OF SHORT DURATION OF THIS WORK, AND NOTWITHSTANDING THE ABSENCE OF PREVIOUS EXPERIENCE, THE USE OF THE WET SIZING METHOD BROUGHT ABOUT A SAVING IN CEMENT WHICH WAS GREAT ENOUGH TO COVER THE ADDITIONAL COSTS DUE TO THE APPLICATION OF THIS METHOD AS WELL AS THE COSTS OF PURCHASE AND ERECTION OF THE WET SIZING EQUIPMENT. THE RESULTS DEMONSTRATED THAT THE USE OF A HYDRAULIC METHOD OF SEPARATION CAN BE ECONOMICAL AND ADVANTAGEOUS FROM AN ENGINEERING POINT OF VIEW IN SEVERAL RESPECTS, EVEN IN NORTHERN REGIONS. /AUTHOR/]]></description>

      <title>INVESTIGATION OF CREEP IN CONCRETE-REPORT 4-EFFECT OF SPECIMEN SIZE AND WET-SIEVING TO REMOVE AGGREGATE LARGER THAN 1-1/2 IN.</title>
      <link>https://trid.trb.org/View/101560</link>
      <description><![CDATA[CREEP MEASURED ON 6- BY 16-IN. CONCRETE CYLINDERS MADE AND TESTED IN 1957 WAS COMPARED WITH THAT MEASURED ON 30- BY 60-IN. CYLINDERS MADE AND TESTED IN 1954 FOR TWO CONCRETE MIXTURES. IN ONE SERIES OF TESTS BOTH SIZES OF SPECIMENS WERE MADE FROM THE SAME MIXTURE PROPORTIONS. THE MAXIMUM AGGREGATE SIZE FOR THIS MIXTURE WAS 1-1/2 IN. IN THE OTHER SERIES OF TESTS THE 30- BY 60-IN. CYLINDER WAS MADE FROM CONCRETE CONTAINING 6-IN. MAXIMUM SIZE AGGREGATE, WHEREAS THE 6- BY 16-IN. CYLINDERS WERE MADE FROM IDENTICAL CONCRETE WET-SIEVED TO REMOVE ALL AGGREGATE LARGER THAN 1-1/2 IN. THE CREEP OF THE SMALL SPECIMENS WAS CORRECTED FOR AUTOGENOUS LENGTH CHANGE. SINCE THERE WERE NO CONTROL SPECIMENS OF 30- BY 60-IN. SIZE, THE CREEP OF SPECIMENS OF THAT SIZE WAS NOT CORRECTED FOR AUTOGENOUS LENGTH CHANGE. TEST RESULTS GENERALLY CONFIRM THEORIES REGARDING CREEP, AND SHOW THAT, IF PRACTICABLE, TESTING SHOULD BE DONE ON LARGE SPECIMENS CONTAINING THE FULL CONCRETE MIXTURE. AT VERY EARLY LOADING AGES, THE CREEP OF LARGE SPECIMENS WAS GREATER THAN THAT OF SMALL SPECIMENS. AT LATER AGES, THE REVERSE WAS TRUE. /AUTHOR/]]></description>

      <title>RAPID METHODS OF ANALYSIS FOR BITUMINOUS ROAD MATERIALS</title>
      <link>https://trid.trb.org/View/95043</link>
      <description><![CDATA[THE FIRST EDITION OF ROAD NOTE NO. 10 APPEARED IN 1951 AND WAS INTENDED TO BE A HANDBOOK FOR ANALYSTS WHO WISHED TO USE THE METHODS RECENTLY DEVELOPED AT THE ROAD RESEARCH LABORATORY IN GREAT BRITAIN, FOR ANALYSING PREMIXED BITUMINOUS MATERIALS IN A TIME VERY MUCH SHORTER THAN THAT WHICH COULD BE ACHIEVED USING THE METHODS SPECIFIED IN BRITISH STANDARD 598:1950. IN THE PRESENT VERSION, THE AIM IS TO REMOVE ANY AMBIGUITIES AND UNCERTAINTIES IN THE PROCEDURE AND TO GIVE CLEAR GUIDANCE WHERE ALTERNATIVES ARE PERMITTED. SOME REVISIONS IN THE PROCEDURE HAVE BEEN MADE. A TABLE GIVING EXTRACTION TIMES FOR DIFFERENT TYPES OF MATERIAL WHEN USING THE SIEVING-EXTRACTOR METHOD HAS BEEN ADDED, TOGETHER WITH INSTRUCTIONS FOR REDUCING THE ANGLE OF OSCILLATION OF THE HEAD WHEN SAMPLES CONTAINING WEAK OR SOFT AGGREGATES ARE BEING ANALYSED. A BRIEF DESCRIPTION OF THE 'AUTOMATIC' RECOVERY OF THE BINDER FROM SOLUTION IS INCLUDED. OTHER SUBJECTS DISCUSSED ARE THE DIFFERENCES IN RESULTS OBTAINED RESPECTIVELY BY WET AND DRY SIEVING, THE ANALYSIS OF MIXTURES CONTAINING NATURAL ASPHALTS, THE RECOVERY OF DICHLOROMETHANE, THE SAFETY PRECAUTIONS THAT SHOULD BE OBSERVED WHEN CARRYING OUT THE ANALYSIS, AND THE USE OF TRICHLOROETHYLENE AS AN ALTERNATIVE SOLVENT IN HOT CLIMATES. /AUTHOR/]]></description>

      <title>WATER STABILITY OF AGGREGATES IN A HEATED BLACK COTTON SOIL: II RESULTS ON THE BASIS OF AGGREGATE-SIZE DISTRIBUTION IN THE DRY STATE</title>
      <link>https://trid.trb.org/View/128015</link>
      <description><![CDATA[A NEW METHOD OF REFRACTIONATION IS PRESENTED WHICH ENABLES ANALYSIS OF WET-SIEVED DRIED AGGREGATES GIVING WATER-STABLE AGGREGATE-SIZE DISTRIBUTION IN THE DRY STATE. SOIL AGGREGATES HEATED TO VERY HIGH TEMPERATURES ARE DISINTEGRATED AND HAVE LOWER WATER STABILITY (THAN THE OPTIMUM VALUE OF AGGREGATION AND WATER STABILITY), DUE TO THE PHENOMENON OF SELF-INDUCED SHATTERING (AUTOPHORETIC DISPERSION), WHICH CAN BE COMPARED TO DESICCATION, DECREPITATION, OR INCIPIENT FUSION. EFFECT OF HEAT ON SOILS CAN NOW BE CLASSIFIED AS FOLLOWS: (1) INITIAL SHRINKAGE AT VERY LOW HEATING TEMPERATURE, (2) LOOSE-PAIR FORMATION, RESULTING IN INSTANTANEOUS REHYDRATION OF THE SEMIHYDRATED AGGREGATES, AND HENCE, DECREASED WATER STABILITY, (3) COLLAPSE OF THE CLAY STRUCTURE, FOLLOWED BY AGGREGATION AND HIGH WATER STABILITY, (4) AN OPTIMUM TEMPERATURE OF HEATING AT WHICH AGGREGATION AND WATER STABILITY ARE BOTH AT A MAXIMUM, AND (5) THE DISINTEGRATION THAT TAKES PLACE AT HIGH TEMPERATURES OF HEATING AND RESULTS IN DECREASED WATER STABILITY, DUE TO AUTOPHORETIC SHATTERING OF THE SOIL AGGREGATES IN CONTACT WITH WATER BECAUSE OF ABSORPTIVE INTERACTIONS.]]></description>

      <title>EVALUATION OF AGGREGATE SIEVING METHODS FOR HOT-MIX ASPHALTIC CONCRETE DESIGN AND PRODUCTION. INTERIM REPORT</title>
      <link>https://trid.trb.org/View/274065</link>
      <description><![CDATA[The purpose of this research was to determine: 1)if the use of wet sieving (with its associated additional effort) to replace or supplement dry sieving is justified, based on the additional knowledge gained and problems alleviated, for the design and production monitoring of hot mixes; and 2) if the use of concrete sieves in place of hot-mix sieves for hot-mix design and production monitoring is justified based on the additional knowledge gained and the unified use of the same sieve sizes for both concrete and hot-mix testing. A minimum of 10 dry, wet and extraction sieve analyses were accomplished on 10 different produced hot-mixes for the SDHPT during the summer of 1982.  In all, four hot-mixes were sampled from four weigh-batch plants, and six were sampled from four drum-dryer plants.  The predominant type of hot-mix sampled was SDHPT Item 340 Type "D".  Most of the aggregate combinations had limestone coarse aggregates and siliceous field sand fine aggregates, although one mixture consisted entirely of crushed gravel and another entirely of pit run iron ore.]]></description>

      <title>EVALUATION OF AGGREGATE SIEVING METHODS FOR HOT-MIX ASPHALTIC CONCRETE DESIGN AND PRODUCTION</title>
      <link>https://trid.trb.org/View/267738</link>
      <description><![CDATA[During the course of Research Study 2-9-80-285 "Asphalt Concrete Mixture Design and Specification," it was desired to address two question concerning sieve analysis of hot-mix asphaltic concrete aggregates which are often raised by personnel of the Texas State Department of Highways and Public Transportation (SDHPT).  These questions are as follows: (1) Would the use of wet sieving (with its associated additional effort) to replace or supplement dry sieving be justified based on the additional knowledge gained and problems alleviated, for the design and production monitoring of hot mixes?  (2) Would the use of concrete sieves in place of hot-mix design and production monitoring be justified based on the additional knowledge gained and the unified use of the same sieve sizes for both concrete and hot-mix testing?  In an effort to answer these questions, a minimum of 10 dry, wet and extraction sieve analyses were accomplished on 10 different produced hot-mixes for the SDHPT during te summer of 1982.  In all, four hot-mixes were sampled from four weigh-batch plants, and six were sampled from four drum-dryer plants.  The predominant type of hot-mix sampled was SDHPT Item 340 Type "D".  Most of the aggregates, although one mixture consisted entirely of crushed gravel and another entirely of pit run iron ore.  Results of this study indicated (1) that there was no general need to adopt wet sieving, and (2) that concrete sives did not offer enough extra information and economy of standardization to merit adopting their usage in place of hot-mix sieves.  The results of this study and the experience of one district did, however, indicate that there may be occasions where wet sieving during the design process may be very useful in precluding a mix design that may generate excessive minus No. 200 material, thus causing trouble with staying within grading limits and design tolerances.]]></description>

      <title>THE SAMPLING AND TESTING OF BITUMINOUS MATERIALS</title>
      <link>https://trid.trb.org/View/161287</link>
      <description><![CDATA[The general attitudes to, and the purpose of sampling and testing are discussed briefly.  Acceptable methods of sampling at the mixing plant, on delivery of the material to the laying site, and after laying are described. Reasons are given for keeping the mass of the bulk sample to about eight times the mass of the test sample.  The need for great care in reducing the bulk sample to a size that is suitable for analysis is emphasised.  Suggestions are made for some checks that should be made to determine whether analysis is worthwhile.  The various possibilities in the preparatory treatment of the bulk sample to obtain the test sample are covered.  The benefits in keeping the mass of the test sample within strictly prescribed limits are stated.  The main problems associated with the procedures for binder content and grading are identified, and the particular difficulties that have arisen when analysing dense-tar-slag mixtures are discussed.  The development of grading methods and the present illogicality of using "wet" sieving and 'dry' specifications for filler is exposed.  It is suggested that routine duplicate testing is of less value than testing two different samples, but duplicate testing is of great value when training testers.  The proper use of precision data is discussed.  A brief statement of the practical problems that can occur during the recovery of bitumen from mixed materials is included.

      <title>TUNNEL SEALING METHOD WITH WATERPROOFED PVC SHEETS</title>
      <link>https://trid.trb.org/View/53026</link>
      <description><![CDATA[A modern method of tunnel sealing with plastic waterproof polyvinyl chloride sheets for tunnels and all kinds of underground constructions is presented.  Using the heating wedge manual tool, butt joints and double seams are welded together thermally and homogeneously.  This procedure is of great advantage, both technically and economically, as the output of the welding works of the plastic waterproof sheets of polyvinyl chloride is greatly increased.]]></description>

      <title>MECHANICAL EQUIPMENT FOR THE GRANULOMETRIC ANALYSIS OF SOILS BY WET PROCESSES</title>
      <link>https://trid.trb.org/View/39060</link>
      <description><![CDATA[The granulometric analysis of clayey soils by let process presents difficulties with regard to the separation of fine elements (which pass through no. 200 a.s.t.m. Sieve) in order to overcome this difficulty, the provincial directorate of highways of corrientes (Argentina) has constructed a mechanical device which prevents the clogging up of sieves, errors by personnel, etc. The above device consists of: a( a vibratory platform and b( two batteries, on the vibratory platform. In each platform there is A recipient which collects the material not retained by the sieve, this material is taken outside by means of A transparent pipe-line. Water distributors have been arranged in such suitable manner that the mixture is homogeneous. The equipment needs two operators. On of whom extracts the mixture from the recipient, disperses it and handles the equipment; the other removes the sieves, places the spare set in position extracts what has been retained in each set of sieves for subsequent drying. The drying time is approximately 10 minutes. The results have been satisfactory. /TRRL/]]></description>

      <title>DEVICE FOR MEASURING SUBSIEVE SIZES IN THE FIELD</title>
      <link>https://trid.trb.org/View/120297</link>
      <description><![CDATA[A DEVICE FOR MEASURING PERCENTAGE FINER BY WEIGHT OF SUBSIEVE SIZES IN THE FIELD IS DESCRIBED. THE DEVICE MEASURES THE SPECIFIC GRAVITY OF A SOIL-WATER DISPERSION WITH A SMALL HYDROMETER (CALLED A URINOMETER) INSIDE A PLEXIGLASS TUBE. TO DETERMINE THE PERCENTAGE FINER THAN A CERTAIN SIZE, THE DISPERSION IS SAMPLED AT A PREDETERMINED DEPTH AND TIME AFTER MIXING, AND THE SPECIFIC GRAVITY OF THE SAMPLE IS MEASURED. RESULTS USING THE NEW DEVICE AGREED WITH RESULTS USING THE STANDARD ASTM HYDROMETER TECHNIQUE. GRAPHS FOR FOUR NONPLASTIC SOILS ARE PRESENTED SHOWING TYPICAL COMPARISONS OF PARTICLE SIZE DISTRIBUTIONS MEASURED BY BOTH TECHNIQUES. APPLICATION OF THE DEVICE TO DECREASE THE TIME REQUIRED FOR WET SIEVING IS DISCUSSED. POSSIBLE MODIFICATION OF PROCEDURES WHEN USING THE DEVICE FOR PLASTIC SOILS IS NOTED. /AUTHOR/]]></description>

      <title>CRITERIA FOR SOILS TO PREVENT FROST DAMAGE</title>
      <link>https://trid.trb.org/View/124243</link>
      <description><![CDATA[AFTER DESCRIPTION OF THE PHENOMENA "FROST HEAVY" AND "THAWING", A SURVEY IS GIVEN ON THE CURRENTLY APPLIED FROST SUSCEPTIBILITY CRITERIA FOR SOILS, GENERALLY BASED ON GRAIN-SIZE LIMITS, FOR PREVENTION OF FROST DAMAGE OF ROADS. THE SPECIFICATIONS FOR NON-SUSCEPTIBLE SOILS AS LAID DOWN IN THE UNITED STATES, CANADA AND WESTERN EUROPE ARE ALSO MENTIONED. IN THE NETHERLANDS, SAND FOR THE SUBBASE IS CONSIDERED TO BE NON-SUSCEPTIBLE FOR FROST, WHEN THE PERCENTAGE BY WEIGHT OF MINERAL PARTICLES FINER THAN 0.050 MM. DOES NOT EXCEED 5%. THIS NUMBER IS DETERMINED BY MEANS OF THE KOPECKI SEDIMENTATION APPARATUS. A DISADVANTAGE OF THIS METHOD IS THAT A SAMPLE OF ONLY 20 G. IS USED. AFTER THE EXAMINATION OF A GREAT NUMBER OF SANDS BY WET SIEVING ON A NO. 200 SIEVE, IT APPEARED THAT THE LATTER METHOD, WHICH PERMITS THE DETERMINATION OF THE PARTICLES FINER THAN 0.075 MM, IS MORE RELIABLE THAN THE KOPECKI METHOD. MOREOVER, THE SAMPLE OF 200 G, NECESSARY FOR SIEVING, IS A BETTER REPRESENTATIVE OF THE SOIL THAN THE SAMPLE OF 20 G. FOR THE SEDIMENTATION TEST. IT IS THEREFORE PREFERABLE TO ADOPT WET SIEVING AS A METHOD OF TESTING. WITH REGARD TO THE DUTCH CLIMATOLOGICAL CONDITIONS IT MIGHT BE CONSIDERED TO DEFINE A SAND TO BE NON-SUSCEPTIBLE, WHEN THE PERCENTAGE BY WEIGHT OF PARTICLES FINER THAN 0.075 MM. DOES NOT EXCEED 10%. SINCE FROST SUSCEPTIBILITY MAY VARY NOT ONLY IN GRADING BUT IN CHEMICAL AND MINERALOGICAL COMPOSITION AS WELL, A RATHER LOW LIMIT OF FINE PARTICLE CONTENT IS REQUIRED TO OBTAIN GOOD RESULTS. /RRL/SWOV/]]></description>

      <title>FOR A STATISTICAL CONTROL OF CRUSHER RUN MATERIAL FOR DENSE GRADED MIX</title>
      <link>https://trid.trb.org/View/102507</link>
      <description><![CDATA[IMPROVEMENTS IN THE QUALITY OF ROAD MATERIALS CAN ONLY BE ACHIEVED BY THE USE OF STATISTICAL CONTROL METHODS. IN THE COURSE OF AN ACCEPTANCE CONTROL OF 0-12,5 MILLIMETER CRUSHER -RUN MATERIAL, THE AUTHOR HAS TRIED THROUGH STATISTICAL ANALYSIS TO ESTABLISH' 1/ THAT THERE WAS A CORRELATION BETWEEN DRY AND WET SIEVINGS AND THAT THE SIGNIFICANT DIFFERENCE WAS SMALL UP TO THE 2 MILLIMETER SIEVE, 2/ THAT A GOOD APPROXIMATION OF THE SAMPLES AVERAGE GRADING CURVE COULD BE OBTAINED BY MIXING AND THEN QUARTERING THROUGH A REDUCING SAMPLER, 3/ THAT THE SIZE OF THE CONTROLLED MATERIAL UNIT BEING TAKEN AS A CUBIC METER, ONE COULD OBTAIN ITS AVERAGE GRADING WITH A GOOD DEGREE OF APPROXIMATION BY TAKING 5 SAMPLES OF ABOUT 4 POUNDS EACH AND DETERMINING THEIR AVERAGE GRADING, 4/ THAT THERE IS A CORRELATION BETWEEN THE 2 MILLIMETER DRY SIEVING AND THE FILLER CONTENT /WET/ AND THAT A POSSIBILITY OF INDIRECT CONTROL OF THE GREATEST VARIATIONS OF THE FINES CONTENT CAN BE INFERRED. THESE CONCLUSIONS COULD LEAD TO STANDARDS FOR A SIMPLE SPECIFICATION OF /OR ACCEPTANCE/ STATISTICAL CONTROL FOUNDED ON THE KNOWLEDGE OF A SIMPLIFIED GRADING /3 OR 4 SIEVES/ THROUGH DRY SIEVING AND ON THE CREATION OF CONTROL CARDS.]]></description>
