    Then its capacity considered is ( (1x10)/) = m 3 / day. That means, a hydraulic excavator can excavate m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as: No. of days required for 10m 3 excavation = 10/ = days.

    Permanent strain and resilient modulus provide direct, quantifiable values that describe two types of deformation (irrecoverable and recoverable) of pavement foundation materials under repeated transient traffic loads. Although the permanent deformation is not directly used in pavement design calculation, it affects the longterm performances of pavement foundations.
