Thanks Keshav for the suggestion. I will certainly cover a few tests on bituminous materials and but a bit advanced ones. I dont thick tests like penetration and sofetning point need to be discussed here. What do you say? Planning videos on Elastic Recovery and MSCR tests soon.

Good & informative video. Please add reference as per MS.02 In the Middle East, all mix designs are followed by MS.02, which is a reference standard that includes guidelines for the design and production of asphalt mixtures. These guidelines are based on international standards such as ASTM and ASHTOO. Thanks

Hello sir, myself Prushottam Kumar from Bihar currently working in a private firm as a Quantity Surveyor for highway projects. BTech civil engineering graduate 2014 from Cochin University of science and technology. I have a keen interest in highway pavement design like Design of earthworks layer, embankment and subgrade, gsb and wmm layers, dbm and bc layers , with step by step procedure with given condition. During BTech, I have performed several tests on soil, aggregate and bitumen. I am thinking of mtech from transportation engineering from nit or iit. Your videos are conceptual, crystal clear with the thoughts. 🙏🙏🙏🙏

Dear sir, I am somesh from Tamilnadu, for BC-2 the minimum binder content as per Mort&h & IRC SP:2022 but in the case of PMB as a minimum binder content 5.6% as per IRC:SP:053-2010. So please suggest the minimum binder content in the case of modified bitumen.

Dear sir how we are control loss of stability in Asphalt wearing Coarse it is coming More than limit percent

@SatishIITR

2 ай бұрын

You mean retained stability is less than code value. It shows that there is problem in the binder. Stability loss indicates the stripping in the mix. Either increase the fine content or use some anti-stripping agent.

Sir what is the difference between drum mix and batch mix design mix please explain

@SatishIITR

Ай бұрын

A batch mix plant produces finished mixtures in batches with short intervals, whereas a drum mix plant can continuously produce mixtures without any interruptions. Both are in use and both have advantages and disadvantages depending upon the size and type of the job.

Sir As per IRC 37 2018 air voids should be 3.5% and as per morth 4% which should follow ?

when DBM is laid in two layers, the lower layer is designed for 3.0 percent air voids keepling little higher binder content. The upper layer is designed for 4 percent air voids. For the single layer DBM, the recommended target air voids in the design is 3.5 %

Flow can also be controlled by either changing the fine content or the binder content. Higher flow value indicates higher binder content. Reduce it slightly to get flow in limits.

Dear respected sir , Please explain why we provide voids in bituminous mixes , These are for what purpose??

@SatishIITR

2 ай бұрын

Two reasons. (1) the layer cannot be compacted to zero air voids, neither in the lab nor in the field and therefore, there will always be some air voids, and (2) Air voids in a layer provide some space for secondary compaction in the field (compaction due to moving traffic) which is needed to avoid cracking and bleeding in the pavement,
