      <title>ANALYSIS OF THE PERFORMANCE OF DEAD-WEIGHT ROLLERS COMPACTING SOIL</title>
      <link>https://trid.trb.org/View/366495</link>
      <description><![CDATA[In this report the methods used to analyse the compaction process using pneumatic-tyred rollers are developed and applied to smooth-wheeled, sheepsfoot and grid rollers. Calculations again using a shear stress with depth approach were applied on the cohesive soils while a bearing capacity method was used on the granular soils.  Comparison of the calculated densities with measured results showed generally good agreement and that the idealisations and analyses developed were capable of determining the levels of compaction achieved by dead-weight rollers.

      <title>EARTHWORKS MACHINERY PLANT, APPLICATIONS, COSTS</title>
      <link>https://trid.trb.org/View/154609</link>
      <description><![CDATA[Using the appropriate standards and codes as a guide the differences in soil types are described and basic values are given for the choice of compaction equipment.  Compaction tests are necessary because compaction is influenced by the properties of the sub-soil and its deformation behaviour and also by the compaction plant and compaction technique used. Rollers are designated according to the compaction method (static or vibrating rollers) the type of forward movement (self propelled or towed rollers), the shape of roller (smooth-, sheeps foot-, stub-foot, grid-, and pneumatic rubber tyred rollers) and the number of rolling units or axles (rolling trains, tandem - and three-wheeled rollers). Each type of roller is described together with the degree of compaction which it can achieve.  (TRRL)]]></description>

      <title>ROADWORK FILLS - A MATERIALS ENGINEER'S VIEWPOINT</title>
      <link>https://trid.trb.org/View/153799</link>
      <description><![CDATA[The problems of sampling and testing boulder clay for its suitability as embankment fill are analysed and the development of suitability criteria described.  Improved standards of compaction and the increasing weight of construction plant are shown to cause troublesome resilient strains in boulder clay compacted wet of optimum moisture content.  The operation of the method specification is discussed.  Finally, the difficulties in separating, depositing and compacting mixed sands and clays in embankments are considered.
