Concrete Solutions for Quieter Pavements on Existing Roadways

چکیده
One of the most pressing issues facing state departments of transportation (DOTs) is highway noise, particularly in urban areas. Where autos are the predominant vehicles on high-speed facilities, most of the noise is generated at the tire-pavement interface. The impact of tire-pavement noise lessens as the percentage of trucks increase and other elements of highway noise—vehicle drive trains and vehicle exhaust systems—become more predominant. DOTs are facing increasingly significant public concern over highway noise. Currently, many urban projects involve the construction of noise walls to mitigate the problem.

Incremental layerwise finite element formulation for viscoelastic response of multilayered pavements
This paper provides an incremental layerwise finite element formulation for the viscoelastic analysis of multilayered pavements. The constitutive behavior of asphalt concrete is represented by the Prony series. Layerwise finite element has been shown to provide an efficient and accurate tool for the numerical simulation of laminated structures. Most of the previous research on numerical simula...

In recent years a great number of advanced theoretical - empirical methods has been developed for design & modeling concrete pavements distress. But there is no reliable theoretical method to be use in evaluation of conerete pavements distresses and making a decision about repairing them. Only empirical methods is used for this reason. One of the most usual methods in evaluating concrete paveme...
متن کاملIntroduction and Application of Rotational Abrasion Device to Determine Concrete Pavement Abrasion
Abrasion susceptibility of highway pavements has a great impact on the skid resistance, and consequently accident rate. A rotational abrasion device is introduced, providing the advantage of field simulation of wheel passage, in comparison with existing standard methods. The device was used to measure abrasion susceptibility of concrete pavements with different textures. The obtained results we...
