The main purpose of this paper is to study the effect of annulus thickness on the quality of resin mixture for fully grouted resin bolt. Pullout and mixture tests were made in underground coal mines for the following arrangements: (a) 29 mm borehole diameter, and 19 mm roof bolt diameter with steel wire around the roof bolt; (b) 29 mm borehole diameter,...
View ArticleQuality of compacted fills is essential to the proper functioning of a structure as a whole. Currently, quality control is achieved by testing to determine the deviation of moisture content of recently compacted soil in relation to optimum moisture and degree of compaction reached. Based on the results, deformability, permeability and strength related c...
View ArticleThe characteristics of the subgrade soil, obtained from laboratory and in situ tests, are of fundamental importance to the design of pavements. The tests carried out in the field, such as CBR in situ, Bredboard and others, represent more significantly the conditions of the soil. The Dynamic Cone Penetrometer (DC...
View ArticleThe general characteristics of granular soils reinforced with fibres have been reported in previous studies and have shown that fibre inclusion provides an increase in material strength and ductility and that the composite behaviour is governed by fibre content, as well as the mechanical and geometrical properties of the fibre. The present work presents...
