Are your specifications proprietary - do you specify a favorite contractor?
No. That is the strength of using a true materials and installation specification. Any contractor may bid the work as long as they meet the requirements of the specification. There are some pavement and pavement maintenance contractors who offer what they call specifications on their websites. They usually reference their own company with very generic requirements that cannot be independantly verified. Our specifications frequently reference ASTM (American Society for the Testing of Materials) tests that are widely recognized in the testing and materials community and may be used independantly to assure quality.
