Ish unumdorligi.
Izox. Tashish masofasi 1km dan kam bo‘lgan xollarda xarakat tezligi 20% ga kamaytiriladi.
bu yerda ;
qas - avtosamosvalning yuk ko‘taruvchanligi, t
- grunt yoki materialning zichligi,( =1,5-2,8) t/m3
L - tashish masofasi, (L=2-30) km
tn - avtosamosvalga yuk ortish uchun ketgan vaqt, (tp=0,02-0,18) soat
tp - avtosamosvalning yuk tushirish vaqti, soat (tr=0,05);
KB-vaqtdan foydalanish koeffitsienti, Kv=0,75
KT-texnologik koeffitsient, Kt =0,70
