USE OF PHOSPHOGYPSUM IN EMBANKMENTS
| 项目名称： | USE OF PHOSPHOGYPSUM IN EMBANKMENTS |
| 摘要： | TO CONTINUE THE RESEARCH INTO THE CONDITIONS TO BE FULFILLED TO ENABLE PHOSPHOGYPSUM TO BE USED IN HIGHWAY EMBANKMENTS, IMPROVED SUBGRADES OR INDUSTRIAL FLOOR SLABS. PREVIOUS LABORATORY AND FULL-SCALE INVESTIGATIONS ON EMBANKMENTS PROVIDED A THOROUGH KNOWLEDGE OF THE BEHAVIOUR OF PHOSPHOGYPSUM IN A RAW STATE. IN 1979 IT IS ENVISAGED: TO CONTINUE OBSERVATIONS ON THE BEHAVIOUR OF THE THUMERIES EMBANKMENT NEAR LILLE, PARTICULARLY ON SETTLEMENT AND CRACKING; TO CONDUCT FULL-SCALE ADHESION TESTS ON TEXTILE REINFORCEMENTS AND TO STUDY THEIR INFLUENCE ON CRACKING PHENOMENA; TO CONDUCT GRASSING TESTS ON THE PHOSPHOGYPSUM SHOULDERS OF THE EXPERIMENTAL ROAD IN ROUEN; TO CARRY OUT A BIBLIOGRAPHIC STUDY OF THE FILTERING CAPACITY OF NATURAL SOIL, VIS A VIS POLLUTION RISKS DUE TO WATER HAVING CROSSED A PHOSPHOGYPSUM DEPOSIT. THIS RESEARCH PROJECT SUPERSEDES RESEARCH PROJECT IRRD ABSTRACT NO 500587. |
