What Is Pavement Texture? Quiet Concrete Pavements in Belgium: In particular, the pavement surface texture affects the noise generated by the tires.

ISO Tracks: Specifications

Proceed to Checkout Continue Shopping. You may delete a document from your Alert Profile at any time. We can also assist in design and specifications for new or rehabilitated pass-by noise tracks and minimize your risk of not conforming to the ISO standard.

If you conduct automotive or tire testing following any of these standards, then your track needs to conform to ISO The shape, flatness, and sound absorption properties of the track affect how the sound propagates away from the vehicle. If you are an automotive company, a tire company, or a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO How do I explain to my construction contractor to deliver a pavement with sound absorption coefficient less than eight percent?

Already Subscribed to this document. For surface texture, ISO Such an instrument utilizes the two-microphone method for sound absorption. The purpose of the ISO standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations. Composition of the pavement Maximum chipping aggregate size Sieve grading curve gradation or job mix formula Wearing course thickness Geometry Size and shape Proximity of large reflecting objects Gradient and crossfall longitudinal and transverse slope Surface properties Surface irregularities dips and bumps Surface texture mean profile depth or MPD Sound absorption coefficient.

Successful construction of an ISO track requires expertise in pavements and specifications that span surface texture, smoothness, and noise. Impedance tube for pavement acoustic absorption. The purpose of the ISO standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations. In order to minimize the variation in rolling sound dinn and vehicle sound emission measurements made at different testing locations it is, therefore, necessary to describe exactly the relevant surface properties and specify carefully the properties of the materials, design and construction of the test surface.
