A Comparison of Traffic Noise From Asphalt Rubber Asphalt Concrete Friction Courses (ARACFC) and Portland Cement
Concrete Pavements (PCCP)
A study was conducted by the Arizona DOT to evaluate the potential poise reduction benefits of using Asphalt Rubber Asphalt Concrete Friction Course (ARACFC) as
an overlay for Portland Cement Concrete...

A Noise-Absorbing Road Surface made of Poroelastic Asphaltic Concrete
A new road-surface material, called poroelastic asphaltic concrete (PEAC), has been designed with a view to its acoustic properties.  The aim was to achieve the
greatest possible sound absorption in the frequency ranges...

Bituminous Overlay Reduces Traffic Noise
It’s a little quieter these days next to Crosstown Highway in Minneapolis, Minnesota.  Last August, Hennepin County Public Works Department maintenance crews
placed a thin bituminous overlay on...

Do Road Surfaces with Rubber Give Noise Reductions?
The paper contends that porosity of the surface is responsible for noise reduction and that rubber (dry process) does not directly contribute to noise reduction.  
Reference is made to a new pavement, “poroelastic surface,” under...

Environmental Noise Analysis - Rubberized vs. Conventional Asphalt Overlays   Alta Arden Expressway and Bond Road
In late 1994, Sacramento County retained BBA to perform three additional acoustical analyses of the effects of roadway repaving on traffic noise levels.  The first of
these analyses was a return to the Alta Arden Expressway to re-evaluate the noise reduction provided ...

Report on the Status of Rubberized Asphalt Traffic Noise Reduction in Sacramento County
The purpose of this report is to document the effectiveness of rubberized asphalt as a traffic noise mitigation measure.  Rubberized asphalt is a bituminous mix,
consisting of blended aggregates, recycled rubber and binding agents.  The rubber is often obtained from...
