Cracking Mechanism of Flexible Pavements

Transportation Engineering Journal of ASCE, 1972
THE PAPER DEALS WITH THE CRACKING OF FLEXIBLE PAVEMENTS CAUSED BY SHRINKAGE DUE TO DRYING OF THE SUBGRADE. A CRACKING MECHANISM IN PAVEMENTS IS PROPOSED, BASED ON THE PRINCIPLE THAT CRACKS FIRST APPEAR IN THE SUBGRADE AND ARE AFTERWARDS REFLECTED THROUGH THE ASPHALTIC LAYER.

Permanent Deformation in Flexible Pavements

Journal of Transportation Engineering, 2004
This paper presents a mechanistic-empirical framework for evaluating permanent deformation in flexible pavements. The procedure uses rational material properties and can be used as an analysis tool, as a companion to the design method. The material properties required are (1) the stress dependent modulus of the pavement layers, asphalt concrete and ...

Flexible Pavement Evaluation and Rehabilitation

Transportation Engineering Journal of ASCE, 1977
A method for evaluating a flexible pavement and designing overlays based upon its in-place strength is presented. Strength is determined through a nondestructive dynamic deflection device trade-named Road Rater. Statistical laws are used to determine the characteristic deflection of the pavement, which is then modified to standard conditions.

Review and Assessment of Flexible Pavement

2018
The failure of flexible pavement is termed in a cumulative number of standard axles required to cause a pavement to rut up to a depth of 20 mm or the number of standard axles required to exceed fatigue cracking beyond 20% of the pavement surface area as per the Indian code of practice. This study illustrates the effectiveness of finite element analysis

Flexible Pavement Thickness Design

1988
The thickness design of highway pavements requires the following large number of complex factors to be considered. (1) The magnitude and number of repetitions of the applied wheel loads and the contact area between the tyre carrying the load and the road surface.

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
