On　the　basis　of　the　test　of　the　characteristics　of　aeolian　sand　in　Al＇er-Hetian　desert　highway,　the　compaction,　modular　of　elasticity　and　settlement　for　aeolian　sand　basement　are　monitored　and　analyzed.　The　natural　aeolian　sand　embankment,　whose　moisture　capacity　is　about　1%,　has　been　compacted　well　(natural　compaction　achieves　more　than　95%),　the　modular　of　elasticity　can　be　satisfied　with　embankment　specification　and　the　settlement　is　small,　even　if　compaction　is　a　little　under　the　specification　requests.　Besides,　Aeolian　sand　particles　are　uniform　and　dense,　the　compressibility　is　small.　Roadbed　has　been　compacted　by　heavy　loading　vehicles　during　construction,　so　the　settlement　will　be　steady　after　pavement　is　paved.
