The bolt has a core diameter DK, a thread diameter DG, and a screw-depth of LE. The screw enters the asphalt to a depth of LB where it is anchored in the hole (7) by a fluid mass (8) to a depth of LF. The installation is described by the relationship: DB DG, DB DK, LB LE and O, 2 LE 0.8 LE. The bolt is anchored in a hardened bonding agent which penetrates into surrounding pores.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E399903-T1: [Translated] METHOD FOR FASTENING A TRAFFIC CONTROL DEVICE TO AN ASPHALT ROAD SURFACE on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E399903-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/usk7-gsgr", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/usk7-gsgr", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E399903-T1: [Translated] METHOD FOR FASTENING A TRAFFIC CONTROL DEVICE TO AN ASPHALT ROAD SURFACE"}
