Title: ROADSIDE COVER EQUIPMENT
Accession Number: 00219421
Record Type: Component
Abstract: THE OBJECTIVES ARE TO DEVELOP AND EVALUATE IDEAS AND TO FORMULATE DESIGN PRINCIPLES AND INFORMATION LEADING TO THE PRODUCTION OF EQUIPMENT FOR MORE EFFECTIVE AND ECONOMICAL ROADSIDE DEVELOPMENT AND MAINTENANCE. AN IMMEDIATE OBJECTIVE IS TO IMPROVE EXISTING MACHINES AND DEVELOP MORE EFFECTIVE TECHNIQUES FOR THEIR USE. STUDIES OF MACHINERY PROBLEMS ARE MADE WHEN NEEDED. A SURVEY OF ALL STATE HIGHWAY AGENCIES AND TOLL ROAD AUTHORITIES PROVIDED INFORMATION ON THE TYPES OF EQUIPMENT USED FOR THE ESTABLISHMENT AND MAINTENANCE OF HIGHWAY RIGHT-OF-WAY, AND AN ASSESSMENT OF THEIR PAST PERFORMANCE, CONVENIENCE AND OVERALL PRODUCTION COST. FINDINGS OF THE VARIOUS PHASES OF THE PROJECT ARE REPORTED IN INDIVIDUAL REPORTS AND PUBLICATIONS. THE PROJECT WAS INITIATED IN 1958 BY G. E. PICKARD AT THE AGRICULTURAL ENGINEERING DEPARTMENT, UNIVERSITY OF ILLINOIS. THE JUSTIFICATIONS FOR THE PROJECT WERE THE RAPID INCREASE OF ROADSIDE ACREAGES EXPECTED FROM THE INTERSTATE HIGHWAY SYSTEM CONSTRUCTION AND THE FREQUENT FAILURES OF EQUIPMENT, TECHNIQUES AND FLORA BORROWED DIRECTLY FROM AGRICULTURE TO ESTABLISH AND MAINTAIN ROADSIDE COVER. THE FAILURES ARE NOT SURPRISING AS THE CONDITIONS ALONG ROADSIDE RIGHT-OF-WAY ARE RADICALLY DIFFERENT FROM THOSE IN THE AGRICULTURAL PRODUCTION. THE COVER WAS OFTEN GROWN ON SLOPES SELDOM ENCOUNTERED IN FARM FIELDS OR PASTURE LAND, AND MOST SLOPES CONSISTED OF RAW SUBSOIL. THE SUPERHIGHWAYS PRODUCE DEEPER, LONGER AND STEEPER SLOPES THAN THOSE IN PAST CONSTRUCTIONS AND ESTABLISHING COVER HAS BECOME MORE SEVERE. THE PROJECT WAS CARRIED OUT ON 18-25 ACRES OF GRASS PER MILE OF INTERSTATE HIGHWAY PLUS AN AVERAGE OF 40 ACRES PER INTERCHANGE AND THE EFFECT WAS NOT ONLY TO FIND MODEST IMPROVEMENTS BUT ALSO TO APPROACH THE PROBLEM AS ONE WHERE NEW COVER SPECIES, TECHNIQUES AND MACHINES MIGHT BE REQUIRED.
