121Â Â A P P E N D I X A Web-Based Survey Form Survey for NCHRP Project 20-05/Topic 51-08, âPractice and Performance of Cold In-Place Recycling and Cold Central Plant Recyclingâ This survey is designed to collect key information needed to develop this synthesis. There are a total of 7 questions about various aspects of in-place recycling. The first three questions document contact information, experience with the new AASHTO Provisional Standards, and help locating other regional, local, and city agencies with cold recycling experience. The remaining four questions focus on the size and extent of cold central plant recycling (CCPR) and cold in-place recycling (CIR) programs and any remaining barriers to increased use. Please note, it is as important to collect âdonât useâ information as to collect information about existing programs. The majority of the questions are "check the box" type. There are also opportunities for including further information in the âOtherâ or âAdditional Commentsâ boxes at the bottom of each question. Thank you for taking the time to contribute your valuable information to our database. 1) Contact Information Name ___________________________________ Agency ___________________________________ Position ___________________________________ Address ___________________________________ City ___________________________________ State ___________________________________ Zip Code ___________________________________ Phone ___________________________________ E-mail ___________________________________
