Optimal design on dowel length for cement concrete pavement

Performance of Dowel Bar Retrofitted Concrete Pavement Under HVS Loading

The California Department of Transportation uses Dowel Bar Retrofit (DBR) as a rehabilitation strategy for concrete pavements. Two test sections were dowel bar retrofitted and a third section was designated for control on US 101 near Ukiah, California. All three sections were subjected to accelerated pavement testing using the Heavy Vehicle Simulator (HVS). The HVS results demonstrated a large ...

The Effects of Concrete Pavement Mix Design Parameters on Durability under Freeze and Thaw Condition

This paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. These parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

Concrete Pavement Crack and Seat Performance and Overlay Design

Effect of Performance Model Accuracy on Optimal Pavement Design

In the first part of this paper, an analysis of the data collected during the American Association of State Highway Officials (AASHO) Road Test, based on probabilistic duration modeling techniques, is presented. Duration techniques enable the stochastic nature of pavement failure time to be evaluated as well as censored data to be incorporated in the statistical estimation of the model paramete...

Concrete Block Pavement for Low Volume Roads

Concrete block pavement (CBP) is a durable pavement for carrying light as well as heavy loads, and it is being used widely for construction of city streets, parking places, gas stations, container stacking yards, residential areas and low volume roads. This paper presents the findings of a laboratory investigation on structural behaviour of CBP. Plate load and Accelerated Pavement tests were ca...
