Study on Noise Reduction with Paving Different Low Noise Pavement Materials

This paper evaluates the amount of noise reduction when using different pavement materials in two adjacent lanes, where close-proximity (CPX) method is introduced to analyze tire/road before and after maintenance. We consider four types materials, including ECA-10, PUC-10, PAC-13, double-layer porous asphalt (PAC-13+PUC-10), these their combinations are paved on lanes. measure with CPX a two-wheel trailer that can install tires tests. study provides some guidelines controlling traffic pollution by combination low materials. From experimental theoretical results, one see highest be obtained both inner outer lanes use pavement. To make balance between performance road maintenance cost, have suboptimal choice, lane uses PUC-10
