注意看题目,“某新建高速公路土方路基路床施工中”,高速公路的路床,压实标准为96%。这个自己看路基施工规范。‚DM¢K­æº#bbs.3c3t.com±À~òçɸG
至于极值,比要求值低5个百分点,这个出处忘记了。‚DM¢K­æº#bbs.3c3t.com±À~òçɸG

第一问选A,看公路检测考试用书第14页土方路基实测项目表格,从题干“高速公路土方路基路床施工”,结合表格可得压实度标准值为96%‚DM¢K­æº#bbs.3c3t.com±À~òçɸG
第二问选D,看公路检测考试用书第14页土方路基实测项目表格下面的注解1:评定路段内的压实度平均值下置信界限不得小于规定标准,单个测定值不得小于极值(表列规定值减5个百分点),由第一问得出标准值为96%,极值为标准值减5个百分点,即压实度的极值等于91%‚DM¢K­æº#bbs.3c3t.com±À~òçɸG

规范中路床压实度至少是96%,极值就是标准值—5%而得到极值。‚DM¢K­æº#bbs.3c3t.com±À~òçɸG
