Viscoelastic Approach to Rutting in Flexible Pavements

Journal of Transportation Engineering, 1995
Permanent deformation (rutting) in bituminous pavements is treated as a linear viscoelastic flow phenomenon and is calculated using the linear elastic layered pavement model VESYS, reported by Kenis in 1978, supplied with equivalent viscous material properties.

Utilization of RAP in Flexible Pavements

2020
In modern days, life without the transportation industry is unimaginable. The roadways play a vital role in improving the economy of the country. As the roadways require necessary strengthening, rehabilitation or reconstruction depending on the severity of the damage caused to the structure during its service life, enormous quantity of RAP will be ...

Numerical Modeling of Flexible Pavements

International Review on Modelling and Simulations (IREMOS), 2015
The road is a civil engineering structure that is not computed as the other structures of the field, for all stakeholders in its design elements characterized by their multidisciplinary settings in their values and behavior. The roadway is a complex system in its structure composed of various heterogeneous materials, its unexpected behavior due to the ...

Optimal Flexible Pavement Design

Transportation Engineering Journal of ASCE, 1978
This paper proposes a model and solution procedure for the optimal design of flexible pavements that finds the best cost achievable for each possible combination of materials without actually computing the layer thicknesses. The primal-dual relationships and complementary slackness conditions of linear programming are used to reduce the required number

FLEXIBLE PAVEMENT DESIGN IN ZIMBABWE.

Proceedings of the Institution of Civil Engineers, 1982
A recommended design procedure for roads in Zimbabwe is presented. Quantatively it is based on CBR, and qualitatively on Texas triaxial tests. It stresses the importance of both subsoil drainage and the need for timely and adequate maintenance, which enable the relatively thin and cheap designs to perform adequately. The economic implications of design
