The 1957 season there was occasional opportunity to make special tests to determine the amount of influence of various construction factors and procedures. Without these objective measurements as a guide each engineer and contractor necessarily bases his viewpoint on the particular experiences he has had, and over a long period or time these men may arrive at good answers to a great many questions about roughness. However, the objective measuring process turns up an occasional surprise of great value, an unsuspected factor, and in any case there is a worth while saving of time, sometimes years, in getting the answers. The tests and results reported here are valuable by themselves as useful information; but when the results can be combined with additional similar measurements or cases their utility will be further enhanced. It has been found that engineers and contractors in the field are not only eager to make full use or all findings and conclusions arrived at, but actually are anxious to use the roughometer tor special tests or their own to answer questions about which they are by nature curious. Their genuinely scientific attitude should be fostered and maintained by providing them all with the results given in this report• and by encouraging t hem to volunteer their own special problems for testing.
