INFLUENCE OF MATERIAL TYPES AND METHODS ON SPECIFICATIONS

The paper first considers specifications generally and identifies two distinct types, viz methods and end product specifications. Types of material are then considered, and their differences, relevant to compaction, identified. Groups of materials and their condition are then rated in a general manner with respect to ease of compaction and compaction plant, layer thickness and moisture condition proposed, in order to achieve the required level of compaction. Particular attention was given to cement treated materials, which pavement designers assume to possess high strength, but which show wide variation in this and other mechanical properties with moderate variation of density. The methods are reviewed further, and the paper argues that fast nuclear methods of density measurement suit both, end product and method specifications. Nondestructive, auscultative methods are argued to have restricted application for density testing. finally, current specifications by several sras are reviewed, where they cover compaction and its control, and the differences highlighted. This paper was presented at Session III: Use of Relative Compaction in Road Construction. For the covering abstract of the conference, see TRIS no. 378031. (Author/TRRL)
