Los ntawm dab tsi yog cov ntsuas ntawm flakiness, qhov ceev ntawm lub ramming ntawm cov khoom yuav nyob ntawm seb.

Kev ua kom muaj kev sov siab nyob ntawm seb muaj pes tsawg tus khov thiab ntxiv yaj. Muaj peev xwm ua rau lub cev npau taws ua rau cov khoom siv dag zog ntawm cov nplej (crushing, deterioration, compaction yog xyuas). Muaj ntau pawg ntau zog:

- siab muaj cim nrog M1200-1400,

- HNUB NYOOG - M800-1200,

- nruab nrab lub zog - M600-800,

- weak-lub zog - M300-600,

- qaug zog heev (M200).

Feem ntau, kev xaiv hom ntawm cov khoom siv no yog txiav txim siab los ntawm cov neeg siv xov tooj cua. Kev tsim nyog rau kev siv yuav tsum raug lees paub los ntawm cov ntawv pov thawj yuav tsum tau ua tiav thiab cov kev txiav txim siab ntawm cov tsev kho mob-tsev kho mob.

- nyob rau hauv qhov kev npaj ntawm lub hauv paus ntawm cov tuam tsev,

- nyob rau hauv kev tsim kho thiab kev kho ntawm txoj kev tsheb thiab kev tsheb ciav hlau,
