Abstract:The excess length, as well as certain other design features of the CHLOE profilometer, make it impractical to tow this instrument at normal highway speeds between the test sections where it is to be used. After more than a year's experience in operating the profilometer on Texas highways, the Texas Transportation Institute developed a light, two-wheel trailer for safely transporting the profilometer at high speed. Normally towed by an automobile, the trailer has certain features designed to minimize the time and effort spent in loading and unloading. However, the dimensions supplied herein should be checked against the dimensions of the particular CHLOE for which a trailer is to be constructed as some dimensions vary between models. The construction details provided in this report may be of interest to other states and agencies who have recently purchased CHLOE profilometers.
