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。}Œò÷ÂÚv¬bbs.3c3t.comÙðà ¢î*¬ã
至于极值，比要求值低5个百分点，这个出处忘记了。}Œò÷ÂÚv¬bbs.3c3t.comÙðà ¢î*¬ã

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%}Œò÷ÂÚv¬bbs.3c3t.comÙðà ¢î*¬ã
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%}Œò÷ÂÚv¬bbs.3c3t.comÙðà ¢î*¬ã

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。}Œò÷ÂÚv¬bbs.3c3t.comÙðà ¢î*¬ã
