WebTrip-ticket system is a recording system for orderly disposal of construction waste to disposal facilities by trucks. Contractor is required to complete a standard trip-ticket form outlining the details of the transportation vehicle, contents of the vehicle (type and approximate volume of waste) and the designated disposal facility. Let us do a test for modulus (G') at a two different speeds at a given temperature. Because time is equivalent to temperature we can calculate that the high speed value will be obtained at low speed at a lower temperature and that the low speed result will be obtained at high speed at a higher temperature. Similarly, if we … See more What do C1 and C2 mean? C1 is a measure of the range of times/frequencies spanned by that process over the entire relevant temperature range.
