Unless you are an expert in pavement design, it may be very difficult to evaluate all of the information that may be submitted to you – let alone find time to do so. Unscrupulous suppliers often try to take advantage of this fact by providing large quantities of information, even though it is not sufficient to show equivalency and may not even be relevant to the application. You can reduce the confusion by writing a project specific specification that includes the information outlined in the checklists we linked above – depending on the application (subgrade stabilization or designing a pavement).
