The purpose of this report is to describe the system for obtaining and handling skid data, including skid testing procedures and data input procedures. While all testing devices used in Virginia are covered (other than the British portable tester), the emphasis is on those procedures to be followed in operating the new skid trailer being obtained by the Materials Division. The testing procedures discussed include (1) the determination of test sites, (2) scheduling of testing, (3) the number of tests to obtain per site, and (4) the use of control site including the frequency of testing. The discussion of data input procedures includes a description of the data elements collected during a skid test, the appropriate input forms to use, and coding techniques as outlined in Appendices A and B.
