The HydroTimer
A precision testing instrument calibrated to meet the
ASTM International E 2380-05 Standard
The HydroTimer is a self-contained outflow meter that tests surface drainage on concrete and asphalt pavements before and after surface preparations like abrading or abrasion retexturing. This device measures the pavement's ability to relieve water pressure at the tire footprint, thus giving an excellent indication of vehicular skidding and hydroplaning potential under wet weather conditions.
The Hydrotimer is available to purchase. $3900.00
The HydroTimer was developed by Skidabrader. We use it to show the results of our Skidabraded surfaces, and Aviation and Transportation Engineers worldwide use it and rely on it.
WHAT IT IS
A self-contained outflow meter that produces consistently accurate results regardless of the operator if the tests are performed in accordance with instructions.
EASE OF USE
The HydroTimer is a hands-off operation with trained personnel. The test provides a
graphic visual display of escaping water and a digital reader.
PRECISION
The HydroTimer is a precision-calibrated instrument designed to meet the
ASTM-2380-05 International Standard.
WHY IT WORKS
The base sealing ring simulates a tire footprint. A measured volume of water is released in the center of the sealing ring, while an electronic timer indicates how long it takes the water to pass through texture voids.
MACROTEXTURE
The HydroTimer shows the surface voids' effectiveness in channeling water from under the tire footprint.
PURPOSE
Measuring the ability of the pavement to relieve water pressure at the tire footprint, thus giving an excellent indication of vehicular skidding and hydroplaning potential under wet weather conditions.
