Standard Test Method for Measuring Pavement Texture Drainage Using an Outflow Meter

Importancia y uso:

5.1 This test method is suitable as a field test to evaluate the surface drainage, and in some cases, the internal drainage of the surface course of a pavement. When used with other tests, the outflow time may be used to evaluate the texture produced by an asphalt concrete mix, a finishing method used on portland cement concrete pavement, and refinishing operations on an old pavement surface. Test results will correlate with other methods such as the CT Meter (Test Method E2157), MPD (Practice E1845), and MTD (Test Method E965).

Note 1: The reciprocal of the outflow time is highly correlated with the MPD except when the surface is highly porous, since the MPD is a measure of the surface texture and does not account for the water flowing through the surface pores.

5.2 The outflow times measured by this method are an indication only, and are not meant to provide a complete assessment of the pavement surface friction, or wet weather safety characteristics.

5.3 This test method does not necessarily correlate or agree with other methods of measuring pavement surface characteristics. It is up to the operator to determine the correlation of each method considered.
