1吨沥青混凝土等于多少立方?希望得到准确答复~不同标号的不同品种都不一样,

还需要知道细粒式沥青混凝土的厚度h1、中粒式沥青混凝土的厚度h2及水稳的模量E3,
则平均模量E0=(h1+h2+h3)/(h1/E1+h2/E2+h3/E3)
将数值代入即可.
给个满意答复吧,呵呵.

应该为8×1.2＝9.6cm.

不确定.空隙率一样时,AC25稍大.

查到沥青混凝土的密度就能算了.我查的,粗粒式2.37t/立方米,细粒式2.35t/立方米,所以粗粒式每立方米385*2.37=912.45元,细粒式每立方米405*2.35=951.75元.粗粒式50厚每平方米912.45*0.5=456.225元,细粒式30厚每平方米951.75*0.3=285.525元.

装载的车辆要大、保温好的泥头车,还要盖帆布

路面现场平整度试验仪连续式平整度仪法
1．试验目的与适用范围
用于测定路表面的平整度,评定路面的施工质量和使用质量,但不适用于在己有较多坑
槽、破损严重的路面上测定.
2．仪器设备
(1)连续式平整度仪：
除特殊情况外,连续式平整度仪的标准长度为3m,其质量应符合仪器标准的要求.中间为一个3m长的机架,机架可缩短或折叠,前后各有4个行走轮,前后两组轮的轴间距离为3m.机架中间有一个能起落的测定轮.机架上装有蓄电源及可拆卸的检测箱,检测箱可采用显示.记录、打印或绘图等方式输出测试结果.测定轮上装有位移传感器,自动采集位移数据时,测定间距为10cm,每一计算区间的长度为1oom,ioom输出一次结果.当为人工检测,无自动采集数据及计算功能时,应能记录测试曲线.机架头装有一牵引钩及手拉柄,可用人力或汽车牵引.
(2)牵引车：小面包车或其他小型牵引汽车.
(3)皮尺或测绳.
3,试验要点
(1)选择测试路段路面测试地点,同3m直尺法.
(2)将连续式平整度测定仪置于测试路段路面起点上.
(3)在牵引汽车的后部,将平整度的挂钩挂上后,放下测定轮,启动检测器及记录仪,随即启动汽车,沿道路纵向行驶、横向位置保拧稳定,并检查平整度检测仪表上测定数字显示、打印、记录的情况.如检测设备中某项仪表发生故障,即停车检测,牵引平整度仪的速度应均匀,速度宜为5km/h,最大不得超过12km／h.
在测试路段较短时,亦可用人力拖拉平整度仪测定路面的平整度.但拖拉时应保持匀速前进.
4．计算
(1)连续式平整度测定仪测定后,可按每10cm间距采集的位移值启动计算：100m计算区问的平整度标准差,还可记录测试长度、曲线振幅大于某一定值(3mm、5mm、8mm、10mm等)的 次数、曲线振幅的单向(凸起或凹下)累计值及以3m机架为基准的中点路面偏差曲线图,并打印输出.当为人工计算时,在记录曲线上任意设一基准线,每隔一定距离(宜为1.5m)读取曲线偏离基准线的偏离位移值di .
(2)每一计算区间的路面平整度以该区间测定结果的标准差表示.
(3)计算一个评定路段内各区间平整度标准差的平均值、标准差、变异系数.
5．报告
试验应列表报告每一个评定路段内各测定区间的平整度标准差.各评定路段平整度的平均值、标准差、变异系数以及不合格区问数.

答案应该是D,矿粉的亲水系数小于1,以保证和沥青良好的黏附性.

柴油可以溶解沥青,如果用柴油就会把沥青溶解.

由于你没有说清楚是哪种类型的混合料,因此范围较广,应该在2.2.7之间.

1,矿粉是要加热的.在JTG E20-2011那本规范上的T0702试件制作方法中有明确提到矿粉单独放,然后加热.
2,流值准确至0.1mm,仪器上显示数值如果是小数点后一位的,就直接记录,如果显示是小数点后两位的,修约后记录,例如测出来是33.33,则记录33.3mm.
3,稳定度精确至0.01kN,你说的实验仪器要求能够准确读到100N,那是仪器要求而已,我们做试验一切以规范为准,所以如果你仪器精度达不到,必须换仪器.

IRI是国际平整度指数.

At - 40 DEG to10 DEG C temperature range,the lower the temperature,asphalt concrete and the incorporation of polyester fiber asphalt concrete and its failure bending strain decreases,i.e.,the lower the temperature,asphalt concrete and the polyester fiber asphalt concrete anti deformation capacity are getting worse.But under the same conditions,polyester fiber,the asphalt concrete anti deformation ability.In the experimental temperature range,adding 0.2% polyester fiber asphalt concrete damage bending strain at different temperatures can be improved an average of 53.6%,with 0.35% of polyester fiber asphalt concrete damage bending strain at different temperatures can be improved an average of 79.8%,with 0.5% of polyester fiber asphalt concrete damage bending strain at different temperatures to an average increase of 132%.This shows that polyester fiber asphalt concrete in low temperature and can effectively prevent the damage of crack formation and development,when there are cracks,bridge in interstitial fiber as a reinforcing rib to the role,in the same under the action of stress,because the fibers from the matrix gradually pulled out can be delayed crack formation and expansion,increase specimen damage when the width,so that the asphalt concrete specimen exhibited greater deformation capacity and ductility.Therefore,the higher the content of fiber,achieve the ultimate strength of the specimen by the failure strain is greater.

通常要求气温高于15度,气温对沥青混凝土的摊铺稳定影响很小,因此不用管它,只要看好摊铺温度就行了.

粗粒式沥青混凝土的比重为2.36t/m3, 中粒式沥青混凝土的比重为2.35t/m3, 细粒式沥青混凝土的比重为2.30t/m3,
1500立方米应该在34500吨以上
