industries.<\/li>\n\n\n\n<li>Particularly in areas where a considerable amount of copper slag is produced.<\/li>\n\n\n\n<li><strong>Production of cold asphalt mix does not require high investment in equipment.<\/strong><\/li>\n\n\n\n<li>This makes it economically relatively pollution-free (no objectionable fumes or odors).&nbsp;<\/li>\n\n\n\n<li>Cold asphalt mixes can be used both for initial construction (100% virgin mixes) and for recycling of asphalt pavements.<\/li>\n\n\n\n<li><strong>Geotextiles are mostly used in road construction<\/strong>, especially to fill gaps between the roads to improve soil structure.\n<ul class=\"wp-block-list\">\n<li>Geotextile makes poor soil more beneficial for use and then easy to build in difficult places also.<\/li>\n\n\n\n<li>It helps to prevent the erosion of soil but allows the water to drain off.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Portland cement and hot asphalt mix are&nbsp;the&nbsp;major CO<sub>2<\/sub>&nbsp;emitters<\/strong>.<\/li>\n\n\n\n<li><strong>Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of
