一、试验目的9ðNô|c bbs.3c3t.com*€¡Mí_}

9ðNô|c bbs.3c3t.com*€¡Mí_}
测定基层(或底基层)、砂石路面及路基土的各种材料压实层的密度和压实度。9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
二、试验标准9ðNô|c bbs.3c3t.com*€¡Mí_}
执行规程:《公路路基路面现场测试规程》JTJ 059-19959ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
三、指标9ðNô|c bbs.3c3t.com*€¡Mí_}
压实度。9ðNô|c bbs.3c3t.com*€¡Mí_}

四、试验方法9ðNô|c bbs.3c3t.com*€¡Mí_}
1、9ðNô|c bbs.3c3t.com*€¡Mí_}
计算干密度9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
ρ——湿密度(g/cm39ðNô|c bbs.3c3t.com*€¡Mí_}
mt——试洞中取出的土样质量(g9ðNô|c bbs.3c3t.com*€¡Mí_}
mb——填满试洞所需砂的质量(g9ðNô|c bbs.3c3t.com*€¡Mí_}
ρs——量砂密度(g/cm39ðNô|c bbs.3c3t.com*€¡Mí_}
ρd——干密度(g/cm39ðNô|c bbs.3c3t.com*€¡Mí_}
w——含水率(%9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
2、9ðNô|c bbs.3c3t.com*€¡Mí_}
计算压实度9ðNô|c bbs.3c3t.com*€¡Mí_}
压实度 = 干密度 / 最大干密度9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
3、9ðNô|c bbs.3c3t.com*€¡Mí_}
计算代表值、合格率9ðNô|c bbs.3c3t.com*€¡Mí_}
按照《公路工程质量检验评定标准》附录B9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
K——代表值9ðNô|c bbs.3c3t.com*€¡Mí_}
k——平均值9ðNô|c bbs.3c3t.com*€¡Mí_}
ta——保证率9ðNô|c bbs.3c3t.com*€¡Mí_}
S——标准差9ðNô|c bbs.3c3t.com*€¡Mí_}
n——检测点数9ðNô|c bbs.3c3t.com*€¡Mí_}
K0——标准值9ðNô|c bbs.3c3t.com*€¡Mí_}
9ðNô|c bbs.3c3t.com*€¡Mí_}
五、合格判定9ðNô|c bbs.3c3t.com*€¡Mí_}
1、9ðNô|c bbs.3c3t.com*€¡Mí_}
当代表值大于标准值,且全部单点值大于极值,按不低于规定值减2个百分数的单点值计算合格率。9ðNô|c bbs.3c3t.com*€¡Mí_}
2、9ðNô|c bbs.3c3t.com*€¡Mí_}
当代表值小于标准值,或有单点值小于极值,为不合格。QQ:6545905999ðNô|c bbs.3c3t.com*€¡Mí_}
