@@qualitycontrolengineer8348 No, I did not say these are not used in GSB mix. I said that for getting the gradation of GSB, in the given example case, aggregates of 20 mm and 6 mm are not needed. It all depends on the grading of aggregates of different sizes available at site. The final mix should conform to MoRTH grading. I hope it is clear.

Wonderful! Thanks!

Sir i have one doubt. As we conduct mdd/omc test we apply 55 blows for each layer. Therefore to get 98% of MDD how many blows per layer should we apply when casting CBR mould.

CBR mould is casted as per standard procedure at OMC.

Thank you sir for this valuable video. Sir how do we test unconfined compressive strength of GSB mixes?

@SatishIITR

UCS can be determined as per ASTM D 1633. You need to apply vacuum to retain the shape of the sample.

Very Informative lec sir I have one question Why it is necessary to avoid broken back curve while designing horizontal alignment

@SatishIITR

2 жыл бұрын

broken back curves are too closed spaced and therefore sight distance becomes a problem.

The MoRTH recommended GSB grading are low on permeability. However IRC 58 provides guideline for US grading. This doesnt match with Morth grading. Also the design method for drainage layer given in IrC 58 is for rigid pavement and not flexible. Practically designer have no option to design GSB for flexible pavement other than accepting minimum thickness of 200mm as recommended. Since drainage layer is an important element is there a method for designing gsb for flexible pavement with appropriate permeability? Also especially when we are now constructing wider pavement for expressways.Kindly advice.

@SatishIITR

2 жыл бұрын

when you lay GSB in two layers, the lower layer of 100 mm thickness acts as drainage layer. You can certainly use the philosophy of design given in IRC:58 to design this layer.

Grading 3 and 4 are gap graded or open graded sir?

@SatishIITR

Gap graded. The necessaty condition for an open grading is stone on stone contact. Watch my video on Open Graded Friction Course and another one on SMA
