REPORT OF COMMITTEE ON HIGHWAY GUARD: TESTS AND STUDIES, 1924-1941
TESTS ON HIGHWAY GUARD ARE OF TWO GENERAL TYPES (1) DEVELOPMENT TESTS OR THOSE LEADING TO THE DEVELOPMENT OR IMPROVEMENT OF A PARTICULAR TYPE OR DESIGN, AND (2) DIFFERENTIATING TESTS IN WHICH SEVERAL TYPES OR DESIGNS ARE CHECKED AGAINST EACH OTHER AND THEIR PERFORMANCE NOTED. IN EITHER CASE THE FIELD TEST CORRELATED WITH LABORATORY CONTROL TESTS REPRESENTS THE DESIRABLE METHOD OF APPROACH. THE GENERALLY ACCEPTED FIELD TEST CONSISTS OF PROJECTING A FREE RUNNING, DRIVERLESS AUTOMOBILE (CAR, BUS OR TRUCK) DOWN AN INCLINE AND INTO A SHORT SECTION OF GUARD, AT AN ANGLE OF 20 DEG AT VARIOUS SPEEDS, AND NOTING THE REACTION OF THE STRUCTURE AND VEHICLE TO IMPACT. /AUTHOR/
