Viscoelastic–Viscoplastic Model with Damage for Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: A viscoelastic (VE)–viscoplastic (VP) model for characterizing asphalt concrete behavior is described. The parameters of the model are determined in the prepeak region of the loading, under small load. It includes two ...
Rigid‐Pavement Evaluation Using NDT—Case Study
Publisher: American Society of Civil Engineers
Abstract: A case study of a highway rigid‐pavement evaluation using deflection‐based NDT is presented. The test section consists of 280 mm of concrete, 150 mm of cement‐stabilized base, and 150 mm of gravelly sand on a clayey subgrade. ...
Permanent Deformation in Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Dynamic Linear Back Calculation of Pavement Material Parameters
Publisher: American Society of Civil Engineers
Abstract: The dynamic linear back calculation procedure for estimating pavement material properties is presented. Two approaches based on the fitting of the data in the time and frequency domain are described in detail. The time‐domain ...
Granular Material Characterization for Mechanistic Pavement Design
Publisher: American Society of Civil Engineers
Abstract: This paper presents a procedure for characterizing granular base and subbase materials to provide the properties needed by the mechanistic methods for pavement design. It includes repetitive testing under different confining ...
Extension of CBR Method to Highway Pavements
Publisher: American Society of Civil Engineers
Abstract: The CBR design method for flexible airfield pavements was modified in 1971, on the basis of full‐scale tests. A new load repetition factor and Equivalent Single Wheel Load computation scheme were introduced and implemented ...
Advanced Testing and Characterization of Asphalt Concrete Materials in Tension
Publisher: American Society of Civil Engineers
Abstract: The modeling of asphalt concrete materials is currently handled using linear viscoelasticity (VE) and viscoplasticity (VP) with damage. Exploratory frequency sweep and creep and recovery test results indicate that the ...
Experiment Design Approach to Nondestructive Testing of Pavements
Publisher: American Society of Civil Engineers
Abstract: An analysis of the errors involved in both the nondestructive testing data collection and the modeling of a pavement structure is presented. The errors are separated into: (1) Random errors associated with the measuring ...
Analysis of Pressure Distribution under Falling Weight Deflectometer Loading
Publisher: American Society of Civil Engineers
Abstract: An analysis of the pressure distribution beneath the loading plate of a falling weight deflectometer is presented. The analysis is conducted in two stages: (1) Rigid plate deformation shapes without the rubber pad are ...
Practical Applications of Models for Pavement Maintenance Management
Publisher: American Society of Civil Engineers
Abstract: This paper presents a pavement maintenance management system (PMMS) composed of the following modules: (1) Pavement‐network identification; (2) pavement condition survey and rating procedures; (3) distress‐prediction models; ...
