      <title>COMPARISON OF REPAIR METHODS FOR RUTTING CAUSED BY HORSE AND BUGGY. FINAL REPORT</title>
      <link>https://trid.trb.org/View/349418</link>
      <description><![CDATA[This research project evaluated repair methods for rutting caused by horse and buggy traffic.  This problem is the result of the chiselling action of the carbide tipped horseshoes commonly used in many Amish communities in Pennsylvania.  The evaluation included four methods of repair.  Three test sections were established on Traffic Route (T.R.) 340 near Bird in Hand, Pennsylvania.  These sections involved the performance of an ID-2 special blend, Ralumac Latex Modified Bituminous Emulsion Mixture, and FJ-1 wearing course with 100% steel slag aggregate.  The final test section, located on T.R. 741, was an ID-2 fine binder mix.  The research incorporated the evaluation of the performance of the repair materials, as well as the cost and benefits of the construction methods.  The experimental test sections were monitored over a period of approximately five years.  Results of this evaluation indicate that the use of an ID-2 mix is the most effective method to repair ruts and prevent extensive rerutting.  One successful treatment involved milling the ruts and placing ID-2 wearing in the milled area.  A second treatment involved the placement of full-width ID-2 binder and wearing courses.]]></description>

      <title>STABILIZATION OF SANDS BY ASPHALT EMULSION</title>
      <link>https://trid.trb.org/View/66646</link>
      <description><![CDATA[This laboratory study investigates whether sands and sand- clay aggregates are amenable to stabilization by asphalt emulsion.  Marshall tests were used to evaluate the stability of emulsion-treated sand.  Microscopic examination of the treated aggretgates revealed the nature and extent of bitumen coating and spreading characteristics of bitumen binder.  The results show that well-graded sands with sufficient silt-clay material respond well to emulsions. Portland cement in trace quantities is required, however, to improve the water susceptibility of the mixtures.  Because of its superior bonding to siliceous aggregate and its rapid setting tendencies, cationic emulsion is preferred in sand stabilization.  Recommendations concerning mixing and compaction moisture are presented.  This paper shows that either too little or too much mixing time will result in less than optimum coating.  A hypothesis concerning the mechanism of emulsion bonding to aggregates--dry as well as prewet--is proposed.]]></description>

      <title>SLURRY SEAL OPERATION PAVES TEST BIKE PATH</title>
      <link>https://trid.trb.org/View/47148</link>
      <description><![CDATA[A trial application is described of slurry seal for renovation and improvments of shoulders for use as bicycle paths on a state route (333) in Maryland.  A thin slurry of well graded stone aggregate, asphalt emulsion and water was applied on a worn, old surface.  Cost beneifts are claimed for this process, based on both production rate and the reduction of men and equipment.  This project used two Young slurry seal machines (734 SB models and 7.3 cubic-yard capacities) and a JCB front end loader for charging the machines with aggregate.  The production rate was bout 100 ft. per minute.  The sequence of operations is briefly outlined.  If this project is successful slurry seal will be considered for statewide use in conversion of shoulders to bike paths and possibly in regular maintenance.]]></description>

      <title>RUBBERIZED ASPHALT PAVEMENTS: CONSIDERATIONS ON TEST RESULTS</title>
      <link>https://trid.trb.org/View/21291</link>
      <description><![CDATA[This is a preprint of a paper presented at the International Symposium on the Use of Rubber in Asphalt Pavements, Salt Lake City, Utah, May 1971.  The results are discussed of tests which were made on highway surfaces in Italy in 1969 and 1970 during the application of asphalt concrete containing "elastra" synthetic latex.  These tests were conducted on road samples as well as on samples taken from the mixing plant, with the object of studying and testing a number of factors showing the effects of using latex in these mixtures.  It is, at present, the practice in Italy to add the elastomer in latex from while mixing the aggregates with bitumen in the plant.  A series of tests were made which demonstrate that the latex should be introduced a few seconds after starting to spray with bitumen.  Further test showed the stress reaction of asphalt concrete with and without an elastomer, to evaluate the effects of synthetic rubber on the useful life of a flexible pavement.  Further studies were made on the deformation characteristics of these pavements, together with their skidding resistance properties.]]></description>

      <title>USE OF ASPHALT-LATEX EMULSION IN THIN WEARING SURFACES FOR STEEL BRIDGES AND STRUCTURES</title>
      <link>https://trid.trb.org/View/101292</link>
      <description><![CDATA[ON CERTAIN TYPES OF BRIDGES, CONSIDERABLE ECONOMY CAN BE ACHIEVED, THROUGH A REDUCTION OF DEAD WEIGHT, BY SUBSTITUTING FOR THE CONVENTIONAL PORTLAND CEMENT CONCRETE PAVEMENT A LIGHT WEIGHT STEEL DECK WITH A PROPER WEARING SURFACE. STEEL DECKS, WHETHER SMOOTH, CHECKERED OR OF THE OPEN GRID TYPE HAVE PROVED TOO HAZARDOUS FROM THE SKID STANDPOINT. THE RESEARCH PROGRAM HAS CONSISTED OF THE DEVELOPMENT AND TESTING OF SPECIAL BINDING AGENTS WHICH MUST RESIST THE TRACTIVE EFFECTS OF HEAVY LOADS AND PROVIDE A PROPER BOND TO STEEL, WOOD OR CONCRETE SURFACES. THE BINDER MUST ALSO WITHSTAND CONSIDERABLE VIBRATORY AND DEFLECTION STRESSES UNDER RAPID IMPACT LOADING OF RELATIVELY LIGHT STEEL PLATES AND EXHIBIT GOOD DURABILITY QUALITIES IN ITS ABILITY TO WITHSTAND WATER ACTION, AND CHANGES IN PHYSICAL CHARACTERISTICS. THE AGGREGATES, CONSTITUTING THE WEARING COVER MUST PROVIDE AN ANTI-SKID SURFACE AS WELL AS OFFER A HIGH RESISTANCE TO CRUSHING UNDER IMPACT LOADS. ORIGINAL FIELD TRIALS IN 1947 WERE MADE ON A BASCULE BRIDGE WITH A WOODEN DECK WHERE ASPHALT-LATEX EMULSION WAS USED AS THE BINDER FOR THE CRUSHED AGGREGATE PROVIDING THE WEARING COVER. THIS WEARING SURFACE IS IN GOOD CONDITION AFTER SEVEN YEARS OF SERVICE AND IS CARRYING A FAIRLY LARGE VOLUME OF HEAVY TRAFFIC. IN THE SUMMER OF 1952, ANOTHER EXPERIMENTAL SURFACE WAS PLACED ON A RELATIVELY LARGE STEEL PLATE DECK BRIDGE CROSSING ULATIS CREEK IN SOLANO COUNTY. THIS BRIDGE WAS DECKED WITH BOTH PLAIN AND CHECKERED STEEL PLATES AND WAS SURFACED WITH SCREENINGS BONDED TO THE DECK WITH ASPHALT-LATEX EMULSION AND LUMNITE CEMENT-LATEX. JUDGING BY THE PERFORMANCE RECORD OF THE TWO PROJECTS IT APPEARS ENTIRELY FEASIBLE TO APPLY ADEQUATE LIGHT WEIGHT WEARING SURFACES, EXHIBITING SUITABLE ELASTIC PROPERTIES TO RESIST SEVERE CONDITIONS OF VIBRATION AND DEFLECTION AND ALSO PROVIDE DESIRABLE SKID RESISTANCE QUALITIES. /AUTHOR/]]></description>
