TEMPERATURE AND VEHICLE SUSPENSION EFFECTS

THE FIRST WINTER SURVEY CONDUCTED WITH A ROAD METER IN WISCONSIN OCCURRED DURING THE WINTER OF 1968--1969 OVER THE ENTIRE RURAL INTERSTATE SYSTEM. THE ENTIRE SYSTEM WAS SURVEYED AGAIN IN THE SUMMER OF 1969, THE WINTER OF 1969-- 1970, THE SUMMER OF 1970, AND THE WINTER OF 1970--1971. BY THE SUMMER OF 1971 IT WAS EVIDENT THAT WINTER PSI VALUES WERE GENERALLY SLIGHTLY HIGHER THAN THE SUMMER VALUES FOR THOSE PAVEMENTS WITH RELATIVELY GOOD LONGITUDINAL PROFILES. COMPARATIVE TESTS WERE MADE WITH THE ROAD METER AND A CHLOE PROFILOMETER IN THE WINTER OF 1971. IT WAS DETERMINED THAT AT TEMPERATURES BELOW 20 F THE ROAD METER GIVES CONSISTENTLY HIGHER RATINGS THAN AT HIGHER ONES, PERHAPS BECAUSE OF A STIFFENED VEHICLE SUSPENSION SYSTEM.
