      <title>THE SHELL BITUMEN HANDBOOK</title>
      <link>https://trid.trb.org/View/356361</link>
      <description><![CDATA[This handbook provides an up to date guide to the properties and applications of bitumen for the civil engineer in road and airfield construction and maintenance.  The manufacture, storage and handling of bitumen are explained, followed by a comprehensive section on specifications and quality. Bitumen emulsions are dealt with in a special chapter.  The mechanical testing and physical properties of bitumen, its structure and rheology, properties such as durability and adhesion, and the influence of these properties on performance in practice are all set out in individual chapters.  A separate chapter covers the modification of bitumen with various admixtures to improve performance.  Six chapters present aspects of bituminous mixes, including types of mix, manufacture and testing, mechanical properties, transport, laying and compaction and mix design. The analytical design of flexible pavements and surface dressing are covered in separate chapters.  The text is supported throughout by graphs, drawings and photographs, and bibliographic references are supplied at the end of each chapter. (TRRL)]]></description>

      <title>A ZERO-RELATIVE-VELOCITY BELT SKIMMER, STAGE II - CONFIRMING TESTS AND PROTOTYPE DESIGN</title>
      <link>https://trid.trb.org/View/56389</link>
      <description><![CDATA[A 40-foot-long prototype skimming vessel has been designed which uses twin floating sorbent belts to recover spilled oil in 6-8 knot currents. Oil recovery rates up to 600 gpm are possible with the prototype because the composite belts are propelled at the same speed as the water (relative to the vessel). The performance of this zero-relative-velocity (ZRV) belt arrangement was tow-tested at full scale in calm water and in waves. Also tested for proper motion response was a 1/8-scale model of the catamaran vessel that supports the oil recovery apparatus. Results from the test program were used to aid the prototype ZRV Skimmer design effort and quantify its projected oil recovery performance. (Author)]]></description>

      <title>A ZERO-RELATIVE-VELOCITY BELT SKIMMER</title>
      <link>https://trid.trb.org/View/29073</link>
      <description><![CDATA[In the approach to high speed (4 to 10 knots) oil recovery discussed here, oil is collected from the water's surface due to a zero relative velocity (ZRV) between a moving belt and the oil layer. A loosely-tensioned sorbent belt floats like a blanket on the water imbibing oil for a 40-foot contact length before the belt is withdrawn and oil is squeezed out. The composite belt of Astroturf and Fuetron felt readily sorbs oils having viscosities ranging from light diesel oil to No. 6 fuel oil. Full scale simulations of the belt and wringer show maximum oil recovery rates between 1016 gpm and 2152 gpm for an eight-foot-wide belt at a speed of 6.8 knots. An 11 mm slick of Navy Special fuel oil (270 cs vicosity at 75 F) can be collected at 1296 gpm with only 10% additional water. At 10 knots we project oil recovery rates from 840 gpm for No. 6 fuel oil (2300 cs at 75F) to 2080 gpm and 1680 gpm for diesel oil (4.8 cs at 75F) and Navy Special oil respectively. The analytical and experimental feasibility studies indicate that further development of the hardware is warranted by the projected oil collection performance. (Author)]]></description>

      <title>BITUMENS WITH RUBBER ADDITION</title>
      <link>https://trid.trb.org/View/98061</link>
      <description><![CDATA[BITUMENS FROM ASPHALTIC CRUDE OILS WERE AIR-BLOWN AT 250 DEGREES TO A SOFTENING POINT 15-20 DEGREES LOWER THAN THAT INTENDED FOR THE FINISHED PRODUCT. AFTER THE BITUMEN HAD COOLED TO 180-190 DEGREES, 5-15% ADDITIONS OF POWDERED RUBBER HAVING A GRAIN-SIZE DISTRIBUTION OF LESS THAN 1 MM WERE INTRODUCED. BLOWING WAS RECOMMENDED FOR 4-8 HOURS AT 180-190 DEGREES, THE PRODUCTS WERE USED FOR HYDROFUGE AND ANTICORROSIVE INSULATIONS, JOINTING PASTES, AND AS ADHESIVES. INVESTIGATIONS WERE CARRIED OUT FOR USING THESE PRODUCTS AS ROAD ASPHALTS, FOR THE MANUFACTURE OF ROOFING FELTS, AND AS ANTICORROSIVE PROTECTION OF THE PIPELINES. /LCPC(A)/RRL/]]></description>

      <title>SURFACE TEMPERATURE MEASUREMENTS WITH FELTED ASBESTOS PADS</title>
      <link>https://trid.trb.org/View/102081</link>
      <description><![CDATA[COMPARATIVE DATA ARE PRESENTED FROM FIRE TESTS OF CONCRETE SLABS IN WHICH UNEXPOSED SURFACE TEMPERATURES WERE MEASURED WITH CHROMELALUMEL THERMOCOUPLES COVERED BY TWO TYPES OF FELTED ASBESTOS PADS. IN ALL TESTS THE PADS WERE USED SIDE BY SIDE. HENCE, ALL RESULTS ARE OF A COMPARATIVE NATURE. MOST OF THE DATA ARE FROM TESTS MADE ON 3 X 3-FT CONCRETE SLAB SPECIMENS, 6 IN. THICK, WHICH WERE HEATED ON A SMALL FURNACE FIRED IN CONFORMANCE WITH THE ASTM TIME-TEMPERATURE SPECIFICATION. THE REMAINDER OF THE RESULTS WERE OBTAINED FROM A FULL-SCALE FLOOR ASSEMBLY TESTS AND FROM TWO 40 X 40-IN. SLABS 2 1/2 AND 5 IN. THICK. THE EFFECT OF MOISTURE, SINGLE AND MULTIPLE REUSE OF PADS, TYPE OF SURFACE, AND RATE OF HEATING ARE DISCUSSED. /PCA/]]></description>
