What is RARx?<\/h2><\/div><\/div>[vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text css=”.vc_custom_1639396259694{padding-bottom: 15px !important;}”]RARx is a high-tech product made from end of life tyre powder (60% of its composition) pretreated with bitumen and other additives of mineral origin.\u00a0 <\/strong><\/p>\n

RARx marks an evolution of currently existing technologies, incorporating powdered rubber from end of life tyres into asphalt mixtures.[\/vc_column_text]

  • The final quality of the product and the digestion of the rubber powder particles are ensured when carrying out this process at the place of origin (wet process).<\/li>\n
  • It takes advantage of its versatility and ease of use in asphalt-mixing plants since it is incorporated into the production process of the mixes in question as an additive or an additional fine aggregate (dry process).<\/li>\n<\/ul>\n<\/div>[\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image image=”3860″ img_size=”full”][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_empty_space height=”40px”][vc_single_image image=”3456″ img_size=”full” alignment=”center” onclick=”img_link_large” img_link_target=”_blank”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row type=”vc_default”][vc_column css=”.vc_custom_1498229431694{padding-bottom: 50px !important;}”]

    How do you work with RARx?<\/h2><\/div><\/div>[vc_column_text css=”.vc_custom_1643273914786{padding-bottom: 30px !important;}”]The main advantage of RARx is its ease of use in asphalt-mixing plants<\/strong>[\/vc_column_text]
      \n
    • The RARx is sent to the plant in big-bags or tankers.<\/li>\n
    • It is stored in one of the filler silos.<\/li>\n
    • It is dosed with the aggregates for an even distribution with them before its incorporation into the end product.<\/li>\n<\/ul>\n<\/div>[vc_column_text]In this way, the RARx allows the manufacture of asphalt mixtures of high performances for small works or actions, without energetic extra charges for the plant of manufacture of mixtures and with the versatility of being able to execute works of great or small volume, constant or discontinuous in the time.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”vc_default”][vc_column css=”.vc_custom_1498229431694{padding-bottom: 50px !important;}”][vc_row_inner content_placement=”middle” css=”.vc_custom_1605521703423{background-color: #007f06 !important;}”][vc_column_inner]
