This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

This paper describes a neural network system which executes identification of robot dynamics and controller adaptation in parallel with robot control. The system consists of two parts, Real-World part and Imaginary-World part. The Real-World part is feedback control system for the actual robot. In the Imaginary-World part, the model of robot and the controller are adjusted continuously in order...

the available methods for predicting mechanical characteristics of pavement layers are categorized into two general groups, destructive and non-destructive. in destructive method, using coring and pavement subgrade and performing necessary experiments on them, the quantities of layers properties will be identified. in non-destructive method, the attained deflection is measured by applying the l...

In this paper, the use of Fast Falling Weight Deflectometer (Fast-FWD) is analyzed as a non-destructive and quick test procedure to evaluate efficiency short-span bridges. The Fast-FWD an instrument that can produce broadband dynamic force up impact value 120 KN: constant replicable, providing accurate action measures bridge stiffness in truly short period (30 ms). single-span reinforced concre...

This paper presents a systematic full scale field study on the structural performance of Plastic Cell filled Concrete Block Pavement (PCCBP) for different cell thicknesses subjected to live traffic conditions. Five test sections of various thicknesses viz., 50 mm, 80 mm, 100 mm, 120 mm and 150 mm of PCCBP over 100 mm thick water bound macadam (WBM) sub-base layer has been constructed at the app...
