• DBM/BC work at Site
Whoever giving info is well experienced and covered all aspects
1. Air compressor is used to remive dust and small interfering particles
2. Firstly, Prime coat is applied over its previous GSB layer (Granular Sub Base) to make good bonding among Aggregates used in GSB layer and so that they don't move when Base Layer is poured over them.
3. Then Tack Coat is used to make base layer ready for better adhesion with upcoming bitumen Surface layer (wearing surface), if needed, micro surface sheeting can also be used in areas of high annual Rainfall to prevent water going inside 🤗👌
I think prime coat is applied over WBM or WMM layer not on GSB layer
@@MS-qm2hj na bhai, prime Field pr GSB k upar hi apply krte h and existing surface par Tack coating for upcoming Overlay
Prime coat is applied over WMM to stop the moisture of WMM into BM or DBM. And the Tack coat is used as a binder between BM/DBM and SDBC/Surface . And finally seal coat is sprayed over SDBC/ final surface as waterproofing

DBm may kounsi metal use kartye hai sir plz bolo
Sir pls rolling paas kitne dena chahiye ptr or tendam roller se
Plz sir aese or knowledgable video banao plz🥰🥰👌👌👏👏👏
Bhayya I have a doubt
1) there is no safety for laying traffic vehicles are coming on laying surface
2) before laying it should be complete shoulders there is no shoulders preparation
3)in my observation there is no edge cutting happen in center
4) vehicles are not covered with tarpaulin so that temperature will reduce
Awaiting for your reply
Thank you
