It prevents the pavement from collapsing due to an earthquake and inhibits the formation of cracks and bumps in the asphalt pavement road surface. This allows emergency vehicles to travel on the road immediately after an earthquake, thereby helping to accelerate the initial response to any urgent call to save lives and transport supplies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>By smoothly tracking ground deformations caused by earthquakes while maintaining support performance, cracks and bumps emerging in the asphalt pavement road surface can be inhibited, thereby providing passage to vehicular traffic.<\/li>\n\n\n\n<li>It is easy to lay down a geo-grid and restraining members. As the composite rigid layer is simply built atop the subgrade, construction work can be carried out in a short period of time within blocked-off lanes without having to set up temporary yards for the storage of large equipment.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Uses<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Large-scale earthquake measures applicable to asphalt pavements<\/li>\n\n\n\n<li>Preventing the unequal settlement of soft-ground embankment areas and embankment boundaries<\/li>\n\n\n\n<li>Front and rear of structures <\/li>\n\n\n\n<li>Sinking around buried structures<\/li>\n\n\n\n<li>Bump inhibition<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.nippo-c.co.jp\/tech_info\/images\/general\/large1\/SG04019_1.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Example of Bump-inhibitation<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"240\" src=\"https:\/\/www.nippo-c.co.jp\/en\/tech_info\/wp-content\/uploads\/2024\/03\/SG04019_1.jpg\" alt=\"\" class=\"wp-image-1193\"\/><figcaption class=\"wp-element-caption\">Bump-inhibition effect<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.nippo-c.co.jp\/tech_info\/images\/general\/small\/SG04019_4.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\">HRB (from the side)<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.nippo-c.co.jp\/tech_info\/images\/general\/small\/SG04019_5.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\">General asphalt pavement (from the side)<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.nippo-c.co.jp\/tech_info\/images\/general\/small\/SG04019_6.jpg\" alt=\"\" style=\"width:133px;height:auto\"\/><figcaption class=\"wp-element-caption\">HRB (from the front)<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.nippo-c.co.jp\/tech_info\/images\/general\/small\/SG04019_7.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\">General asphalt pavement (from the front)<\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This construction method involves building a composite rigid layer on the subgrade using a high-strength geo-grid and restraining members.
