The invention provides a penetration coefficient determination apparatus for a permeable
asphalt concrete track board test piece, and a test method thereof. The determination apparatus comprises a test device and a
water supply device, and the test device comprises a
workbench, an overflow water tank, an upper sleeve, a lower sleeve, two flanges, an electronic
thermometer and a measuring cylinder; the outer sidewall of the upper sleeve is provided with water overflow ports connected with the inside of the upper sleeve, the two same flanges are provided with a ring of a slot, and the two flanges and the sleeve are cemented to form an integral body; the lower sleeve is connected through the overflow water tank, and the overflow water tank is provided with an overflow port and a water drainage port; the test piece is placed between the two flanges, a rubber sealing pad is arranged between each of the flanges and the test piece, the flanges are provided with screw holes, and the test piece is fixed through allowing long bolts to
traverse through the screw holes and through using nuts; and the
water supply device comprises a
water storage barrel, a water pump and a power switch. The apparatus has the advantages of reasonable structure, simple operation, satisfactory solving of the seepage problem of the side wall, realization of flexible control of hydraulic gradient, and reasonable and reliable determination result.
