    1. 请评定该路段土方路基质量等级。ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ
2. 如评定结果不合格,那么如何改进该土方路基的质量?如评定结果合格,为了进一步提高该土方路基的质量,则应采取什么措施。ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ

+15×0.75+5×0.9+5×0.8-8-6=64.5 ( )ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ

ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ

   故质量等级评定为不合格。ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ

ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ

    2.改进措施:提高检查项目的合格率,纵观检测项目的合格率和规定分,首先应提高压实质量,进行补充压实,使压实度合格率提高。其次提高平整度合格率;补充质量保证资料,减少扣分;整修外观缺陷,减少扣分。ádßaHMU@|bbs.3c3t.comÊA÷ŸH÷7Õ
