Bulking occurs when a geological material is excavated and the volume of disturbed material is different to the volume of the excavated hole.<\/p>\n\n\n\n<p>The spatial model covers Great Britain at 1:50&nbsp;000 scale and is based upon the <a href=\"https:\/\/www.bgs.ac.uk\/technologies\/the-bgs-lexicon-of-named-rock-units\/\">BGS Lexicon of Named Rock Units<\/a> (LEX), the <a href=\"https:\/\/www.bgs.ac.uk\/technologies\/bgs-rock-classification-scheme\/\">BGS Rock Classification Scheme<\/a> (RCS) and estimations of bulking factor values (available from literature review and web-based resources).<\/p>\n\n\n\n<p>The &#8216;bulking of excavated material&#8217; of rocks and soils is an important consideration in the civil engineering and extractive industries. The change in volume between in situ material and excavated material has implications for storing material in stockpiles on site or moving it off site.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is bulking?<\/h2>\n\n\n\n<p>Bulking is defined as the increase in volume of material when it is excavated from its in situ location. The change in volume is called &#8216;bulking&#8217; and the measure of the change is the &#8216;bulking factor&#8217;.<\/p>\n\n\n\n<p>The bulking factor is the ratio or percentage of the volume change of excavated material to the volume of the original in situ volume before excavation. The bulking factor is used to estimate the likely excavated volumes that will need to be stored on site or perhaps removed from site. The bulking factor can be used to help mange the footprint and volumes of excavated materials as well as calculate vehicle movements (based on their carry capacity).<\/p>\n\n\n\n<p>Bulking is controlled by the type of material (lithology) and the excavation methods used.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Lithological controls<\/h2>\n\n\n\n<p>The factors to consider are:<\/p>\n\n\n\n<ul>\n<li>Rock type or lithology: including grain structure and the propensity of a rock to disaggregate during excavation. The lower the disaggregation the greater the likelihood is of excavated material being poorly sorted with a relatively high bulking factor compared to material that is more disaggregated and better sorted.<\/li>\n\n\n\n<li>In situ porosity or density: if some of the pore spaces of the intact rock collapse when it breaks up, the bulking factor may be reduced.<\/li>\n\n\n\n<li>Particle size distribution: a poorly sorted material tends to exhibit a higher bulking factor. Bulking factor has been shown to be insensitive to the maximum particle size but is related to particle size distribution of a similar shape. Fine particles, such as those from the breaking of rock, reduce the bulking factor.<\/li>\n\n\n\n<li>Resultant particle shape: smaller thickness to width ratios tend to have lower values than more equidimensional blocks.<\/li>\n\n\n\n<li>Rock strength: stronger rocks have a greater bulking factor than weaker ones, where the rock is likely to break during excavation and so producing a greater variation in particle size distribution, producing a lower bulking factor.<\/li>\n<\/ul>\n\n\n\n<p>Some soils have very low density and high water content, approaching or above the liquid limit, that may flow when emplaced after excavation and will not change volume significantly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Excavation methods<\/h2>\n\n\n\n<p>The method of excavation will also have an effect on the bulking factor. The main methods of excavation are digging (easy or hard), ripping, hydraulic hammer or blasting. The method of excavation depends primarily on the mechanical discontinuity (joints) spacing and the strength of the rock.<\/p>\n<\/div><\/div><\/div><\/section>\n\n\n\n\n\n\n\t\t\t\t\t<section   id=\"latest-content-7523-block_6da80aca7699c66a5364c805edd06b99\" class=\"grid-section  primary-background   \" >\n\t\t\t\t\t\t<div class=\"container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row header-of-section\">\n\t\t\t\t\t\t\t\t<div class=\"col-12\">\n\t\t\t\t\t\t\t\t\t<h2>You may also be interested in<\/h2>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row grid-wrap\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"col-lg-6 col-12\">\n\t<div class=\"cards cards-orizontal-sm  cards-find-more  cards-bordered\">\n\t\t\t\t<a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\" class=\"media-wrap\">\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample-150x150.jpg\" class=\"lazy-blur wp-post-image\" alt=\"BGS Geology 250k sample\" data-src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample.jpg\" \/>\t\t\t\t\t<\/a>\n\t\t\t\t<div class=\"info-wrap\">\n\t\t\t<div class=\"info\">\n\t\t\t\t<h4><a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\">Datasets<\/a><\/h4>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<p>We have a wide range of  licensed geoscience data.
