For Employees Careers. BuilderUp formerly The Concrete Store. Download Whitepaper. ASTM C is the standard infiltration test for pervious concrete. We recommend that an infiltration test be performed at least annually in multiple locations to identify where and when maintenance might be needed. The test consists of four main components: Installing the infiltration ring, prewetting the concrete, testing the concrete and calculating the results.

For Employees Careers. BuilderUp formerly The Concrete Store. Download Whitepaper. ASTM C is the standard infiltration test for pervious concrete. We recommend that an infiltration test be performed at least annually in multiple locations to identify where and when maintenance might be needed. The test consists of four main components: Installing the infiltration ring, prewetting the concrete, testing the concrete and calculating the results.

To install the infiltration ring, first clean the surface. The infiltration ring must meet certain size requirements and be marked with two lines on the interior to correctly perform the test. Once secure, pre-wet the concrete and infiltration ring with 8 pounds of water maintaining the head of water between the two marks on the interior of the ring.

Begin timing as soon as the water hits the pervious concrete surface. When water is no longer present of the surface, record the elapsed time of the pre-wetting. The time elapsed determines the amount of water to be used in the actual test. In most cases, 40 pounds of water will be required for the test.

Record the weight. Within 2 minutes, add the proper amount of water to the ring. As with the prewetting stage, we will begin timing when the water impacts the pervious concrete surface and maintain the water head between the two lines marked on the infiltration ring. Again, when water is no longer present of the surface, record the elapsed time of the test. With all of our data points collected, we then perform the infiltration calculation using the mass of the water, the diameter of the infiltration ring and time of the test.

ASTM C1701/C1701M

Historical Version s - view previous versions of standard. More C To determine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged. Visual inspection of concrete cores is the best approach for determining sealing of voids near the bottom of the pervious concrete slab. Both tests methods give comparable results. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
