What are you doing to look into reducing the noise level of the road surface of the highway?
We are using a newly developed hot mix asphalt surface on a recently contracted construction project (pilot project). One of the attributes of this hot mix is the reduction of road surface noise. Results have been verified in the laboratory and in actual placement on freeway facilities in the Atlanta, GA metropolitan area. On our initial pilot project we have taken existing noise level readings and will take final readings at the conclusion of the project to determine its effectiveness and possible use on future projects along the corridor. Again, this is a surface that has proven successful in Europe and Georgia. TxDOT is anxiously anticipating that the same success can be duplicated along portions of the IH 35 corridor.
