IN VIEW OF THE PROPOSED ACCELERATION OF THE NATIONAL ROAD BUILDING PROGRAM, IT IS IMPERATIVE THAT THE CONTRACTOR, THE ROADWAY EQUIPMENT MANUFACTUER, AND THE HIGHWAY ENGINEER POOL THEIR TALENTS IN WORKING OUT A SOLUTION TO MUTUAL PROBLEMS IF THE TASK AHEAD IS TO BE ACCOMPLISHED. TO MEET THE CHALLENGE THAT LIES AHEAD, IMPROVED HIGHWAY DESIGN AND CONSTRUCTION SPECIFICATIONS, THE DEVELOPMENT OF NEW AND BETTER CONSTRUCTION EQUIPMENT, AND A MORE EFFECTIVE USE OF EXISTING EQUIPMENT MUST BE MET. DESIGN STANDARDS HAVE, OF NECESSITY, BEEN CHANGED TO REQUIRE BETTER ALIGNMENT, BOTH HORIZONTAL AND VERTICAL, A MORE LEVEL GRADIENT, FLATTER CROSS SLOPES, WIDER DITCHES, BETTER SIGHT DISTANCES, ETC. THESE IMPROVEMENTS IN DESIGN HAVE PERMITTED A MORE ECONOMICAL USE OF LARGER AND MORE VARIED PIECES OF GRADING AND EARTH MOVING EQUIPMENT. HOWEVER, TO PERMIT THE MOST EFFICIENT USE OF NEW AND EXISTING EQUIPMENT, IT IS NECESSARY TO CONTINUE TO KEEP CONSTRUCTION SPECIFICATIONS ABREAST OF EQUIPMENT DEVELOPMENT AND TO IMPROVE DESIGN WITHIN THE LIMITS OF GOOD CONSTRUCTION PRACTICES. A PERFECT DESIGN AND A PERFECT SET OF CONSTRUCTION SPECIFICATIONS, ALTHOUGH IDEAL FOR AN OBJECTIVE, ARE NOT ENOUGH TO ASSURE THE SUCCESSFUL COMPLETION OF THE HIGHWAY CONSTRUCTION PROGRAM THAT LIES AHEAD. THE EQUIPMENT DESIGNER AND MANUFACTURER, THE CONTRACTOR, AND THE ENGINEER MUST WORK AS A TEAM TO ACCOMPLISH SUCH A PROGRAM. /AUTHOR/
