Hi. Some days when we are coring in rocks,sometime mudstone and muddy material get stuck in the core tube as a result the opperatore open the tube along with the core sample inside. They tried hard to get out the core from tube at this process they hit the tube on ground due to which the core...
If Atterberg limits are totally depandent on clay size particals,then why atterberg not used #200 sieve in astm D4318. As he use #40 sieve pass material
The CBR is generally selected at 2.54 mm (0.10 in.) penetration. If the ratio at 5.08 mm (0.20 in.)
penetration is greater, the test shall be rerun. If the check test gives a similar result, the ratio at
5.08 mm (0.20 in.) penetration shall be used (aashto T193-99…2003)Thn what does this mean?
Is this beacause of that first layer of soil in cbr mold get more compactive enegry and become more compected as compare to the last layer. Because we rotate the cbr mold in an upside down maner and plunger start penetration from first laye of the mold(bottom layer in cbr mold preparation).Amvi...
Great Eire...here the erosion will be controlled by stone pitching and then motor grouting will be done. But this issue come before stone pitching. How and what material will be good to fill the space beneath the chute. Becouse if we dump soil thn how we will compact that
Rienforced concrete chutes have been constructed on highyway embankment side slope. Rain water erode almost all the material beneath the chutes. How we can correct this problem to stablized the chutes. Is there any proper method or remedy for this issue.
Thank you Eire..its in ASTM D2419.its not like what you think.screen pic is attachedhttps://files.engineering.com/getfile.aspx?folder=9159e17e-abde-4d6e-80c6-caa181c6e54f&file=Screenshot_20211102-114540.jpg
Yes sir your thoughts are nice...but why not to the nearest small whole number? Why always next whole number..example 7.1 should be reported as 8 why not 7.
Why during sand equivalent test the reported value should be taken to the nearest higher whole number..is there any scientific reason for that or its just for the purpose of ease..thanks
I feel so lucky that i find this site for my understanding. You seniors guys comments are so valuable to me.thats why i am so active because i hv more confusion and want to clear all of them
