The HydroTimer
A precision testing instrument calibrated to meet the
ASTM International E 2380-05 Standard
The HydroTimer a self contained outflow meter, testing surface drainage on concrete and asphalt pavements before and after surface preparations like abrading or abrasion retexturing. The purpose of this device is to measure 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.
The Hydrotimer is available to purchase. $3900.00
HOW IT WORKS
The HydroTimer was developed by Skidabrader. Not only do we use it to show the results of our Skidabraded surfaces, it is available to and relied upon by Aviation and Transportation Engineers Internationally.
WHAT IT IS
A self contained outflow meter which produces consistently accurate results regardless of the operator as long s 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 effectiveness of the surface voids to channel 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.
