Very informative lecture sir. Thank you !

[@SatishIITR]

Thanks for liking. Please share the link with your friends also.

Very informative video sir

Thanks

Respected Sir, Nice lecture 👍

[@SatishIITR]

Thanks a lot, keep watching

[@betu2010kiit]

Sir, very informative! I was searching for a lecturer on this test.

[@SatishIITR]

Glad it was helpful! Keep watching

[@Anaga12-mj1rd]

Sir....how to measure horizontal deformation....what instrument is used...plz reply 😢😢

[@SatishIITR]

LVDT is used to measure the deformation

[@Anaga12-mj1rd]

Hello sir....is there any alternative...if vaccum container is not available in the laboratory

[@SatishIITR]

NO

[@pratikjaiswal2527]

Hello sir, I am working on snow melting pavements. The application will be in snow prone regions of india like jammu kashmir, himachal pradesh etc . In this situation, should i conduct the test at 25 °C or shall i conduct it at 5-10 °C. Will the same procedure applicable if i conduct it at 5-10 °C.

[@pratikjaiswal2527]

Or if not 25°C, than on what basis should i decide the testing temperature. Please suggest

[@SatishIITR]

Test temperature will be the same but conditioning of specimen should be through freeze and thaw process.

[@avinashmishra2254]

Sir please upload lectures on Rcc minor/major bridges

[@SatishIITR]

Sorry sir, I am not touching that area of structures.

[@abdurahmanifs7322]

Which code is followed for ITS test

[@SatishIITR]

AASHTO 283, the procedure is given in IRC 111, 2009 also

[@KoduruSandeepPCI]

sir i am confused with horizontal (is it across loading axis or perpendicular to it) deformation while calculating tensile strain(if possible please provide setup photo) and from which code did we get this equation.

[@SatishIITR]

It is perpendicular to the load on circumference of the specimen. For calculation of ITS, this strain is not needed, you need failure load only.

[@KoduruSandeepPCI]

@@SatishIITRsir from which code is the equation e= o.52*x taken

[@piyushgarg2137]

sir i am working on a project that is use of vermiculite in bituminous pavement ( using marshall tests ). sir i want some guidance

[@SatishIITR]

How can I help you? write to me on email

[@akshaydev6094]

Sir, How do we prepare the unconditioned samples? Do we have to cure the sample in oven at 60°C for 16h

[@SatishIITR]

NO, Keep it at room temperature and then place in a water bath at 25 C for 2 hours before testing.

[@akshaydev6094]

@@SatishIITR ok sir, What about the air voids content in the sample? Is it corresponding to OBC or 7% air voids?

[@SatishIITR]

@@akshaydev6094 7 percent. Better to watch the video once again

[@dhanrajerande6875]

Sir, In case of Core from site then what about 7% air void? Is it maintain?

[@sayantansasmal1352]

Sir, why we take 7% air void not any other percentage of air void? Or why test is not done in Obc?

[@SatishIITR]

This test is to evaluate the effect of water saturation and laboratory accelerated stripping in a bituminous mix. Therefore higher air voids are needed to allow the water penetration in the sample. 7 percent air voids are specified in AASHTO code to optimize this phenomenon. The test is conducted at OBC only, but with lesser number of blows so as to achieve 7 % air voids.

[@moolchandsingh6650]

Sir ITS test k liye air voids % kitna hota h

[@SatishIITR]

seven percent

[@GajendraSharma-w7h]

Sir ITS and TSR procedure code

[@SatishIITR]

AASHTO T 283 and ASTM D4867

[@moolchandsingh6650]

Sir I am confuse How many Air voids %for ITS . For ITS -7%per ASTM D 6931air voids you give me ans on my comment today. For TSR -ITS test 7% air voids For Mr value test ITS? Given in formula 11.08*ITS-3015.8 & 1.1991*ITS+1170 in IRC 37-2018 sir Pls short out my confusen. ITS -? Tsr -?(ITS) Mr -?

[@SatishIITR]

There is no confusion. Refer IRC 111, 2009 on Specifications for DBM. It gives the procedure of determining ITS and TSR as suggested in AASHTO T283. Air Voids for ITS and TSR should be 7 percent + - 0.5 The Equation given in IRC 37 relating Mr with ITS should never be used as there is practically no correlation between these two parameters. Their testing procedure and test conditions are completely different.

[@moolchandsingh6650]

Thank you sir. One more question Pls For Mr value test casted mould shall be at 7(+-0.5)%air voids or

[@SatishIITR]

@@moolchandsingh6650 Mr is determined at normal Marshall specimen as per design volumetrics (OBC and 4 % air voids)
