Hi Grouser, Thankd for advice. Trafic will be light just for offices around. I am still working on it. Thanks

Hi all, Do you have any experience from international standards if it is possible to eliminate wedging methode in base layer for light duty asphalt paving, say inside the factories where no heavy trucks are allowed? For the heavy duty roads we do crushed stone 0-80 mm fraction then 20-40mm...

emmgjld, Thanks for your time digging in the history. Good job!What I feel now is that the formula is useless bearing in mind that in the books we were talking about so far, there are either mistakes or the other authors did something what I do not understand. Probably nobody has checked the...

Dgillette, I was only talking about the saturated sample of granular material to get effective parameters of soil from direct shear test. mntgoat was talking about underwater testing what I understood like saturated condition. 22222222

Hi BigH, Seems to be that I will have to check that Komornik and David paper. I wish I could have had any library in my site. Just bears waking up after long winter season being not happy with the fact that we closed the access to the salmon main river pass. As for the beer I will have one :-)...

To get effective strength parameters of soil.

Hi all, For BigH I want to say that the line over the 2.132 means maybe only that it comes from statistic evaluation of those 200 soil samples. For PEinc In 5th edition it is as I wrote before. I do not have 4th edition. If you use this formula and the numbers as shown in book as in 4th...

Hi all, Looking for the help on one issue from this book in 5th edition. on the page 392 there is an example how to estimate overburden Ps pressure to restrain expansion. equation logPs=2.132+0.0208(76.6)+0.665(1.67)-0.0269(22.6) =2.132+2.096=0.226kg/cm2 I do not understand...

Ron, Thanks for the answer. I will try to keep the proposed moisture content of crushed stone within +- 2% of OMC. I hope client will accept it. For wedging we use fraction 40-80,20-40 and 5-10mm.

Hi all, Looking for any manual or standards dealing with recommended or required water absorption (min/max)for crushed stone for road base course for wedging method. Any numbers or values will be highly appreciated. thanks

Hi Vporrazzo, Only simple advise. I would also use the casing all the way down from the top to the bottom. Backfill your hole within the casing level and excavate again.We had better ground on our site but still had a problems with high GWL, including artesian.If your site is an industrial area...

Hi Jastan, What is under the 6m loose sand layer? What is the area of your site for development?

Thank you all for your valuable comments. Only just for repeat I want to explain the method of excavation of our bored piles.We used the oscilator with 360 degrees rotation. Casing was inside the oscilator that squeezed the casing and push him down.In the mean time the few tone heavy steel grab...

Thanks for all your information! Piles are 2m in diameter,bored pile and cast in place using casing and oscilator for excavation. Ground is composed of mudstone,silty mudstone,muddy samdstone interbedded with very dense sand/silty sand . SPT values are more than 100 already from 4 m bellow the...

Dear All, Looking for any information, experience, literature on pile foundation remedial works. We may have less friction on few our piles according to the recent loading tests and it will be probably necessary to improve pile capacity against uplift.Settlement is no problem.Unfortunatelly...

Hi Focht3, Thanks for your view on the problem. I am going to have fun next week at the meeting, hoping finall to close this long lasting issue.You konw, 100 people is sometimes 100 opinion(different usually). 22222222

Hi All, Thanks for your remarks. We have finished the cyclic test on neighbour pier.6 cycles on 150 and 2 cycles on 200% of working load. Total settlement for all cycles was 24 mm and after unloading was 17 mm final residual settlement. For 6 cycles we had about 1 mm additional setllement...

Hi Foch,3 Thanks for your answer. Our piles were 2 m in diameter, bored piles using large oscilator and casing for excavation.Not driven piles. The two piles tested(Static loading test)were in the same group but in second test we have lowered down the load about 100 Tone.Now we are going to...

Hi Longisland, Thanks for your answer. What is PDA test?

Sorry, forgot to tell you that samples were compacted to 95% MPD and moisture content was 11 %.
