An Optimization Model for Design of Asphalt Pavements Based on IHAP Code Number 234

Table 5

Construction cost for different materials [26].

Layer	Unit	Unit cost (Rials)
Asphalt concrete	1 m^2 per cm thickness	18500
Asphalt treated base	1 m^2 per cm thickness	15800
Granular base	m^3	149700
Granular subbase	m^3	84900
Tack coat	kg	15600

At this time 1 30000 Rials.
