The result of the prediction model of PCI shows that it is valid to be used in the prediction of the condition of pavement for the same family type These processes were done by (PAVER 6.5.7 software. The filtering and outlier analysis was done by using a polynomial (fourth-degree constrained least squared for statistical process. The development model is depending on the PCI value of 109 sample sections having 57.8 km length, Data collected for pavement distress (type, dimension, and severity were used to find PCI. Accordingly the aim of this paper is to develop a pavement condition index model using PAVER 6.5.7 for a flexible pavement urban roads in the Kerbala city center.

Of sensitivity analysis on a developed flexible pavement life cycle cost model using varying discount rate. Sensitivity analysis on flexible road pavement life cycle cost model The results obtained show the effectiveness of glass fibre grids as reinforcement which, with appropriate design and correct installation, by improving interface shear resistance, can be used to expand the performance of flexible pavements in different ways: by increasing the road service life providing a relevant contribution against superficial rutting or by decreasing the construction costs due to the reduction in the reinforced HMA layer thickness and thus of mineral aggregate required for its construction.
This paper presents findings of a numerical investigation on geogrid reinforced flexible pavement roads, under wheel traffic loads, using a three-dimensional Finite Element Method (FEM). Nowadays, the need to increase pavement service life, guarantee high performance, reduce service and maintenance costs has been turned a greater attention on the use of reinforcements. 3D-FEM Analysis on Geogrid Reinforced Flexible Pavement RoadsĬalvarano, Lidia Sarah Palamara, Rocco Leonardi, Giovanni Moraci, Nicola
