ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
一、试验目的ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ

ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
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。ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
二、试验标准ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
执行规程：《公路路基路面现场测试规程》JTJ 059-1995ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
三、指标ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
压实度。ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
四、试验方法ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
1、ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
计算干密度ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ρ——湿密度（g/cm3）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
mt——试洞中取出的土样质量（g）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
mb——填满试洞所需砂的质量（g）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ρs——量砂密度（g/cm3）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ρd——干密度（g/cm3）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
w——含水率（%）ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
2、ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
计算压实度ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
压实度 = 干密度 / 最大干密度ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
3、ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
计算代表值、合格率ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
按照《公路工程质量检验评定标准》附录B。ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
K——代表值ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
k——平均值ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ta——保证率ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
S——标准差ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
n——检测点数ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
K0——标准值ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
五、合格判定ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
1、ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
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。ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
2、ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
当代表值小于标准值，或有单点值小于极值，为不合格。QQ:654590599ÅïQÐYÞª;bbs.3c3t.comDaÅ"EÁyÈÆÐ
