PREFACEThese standard specifications are to be used on contract work awarded by theColorado Department of Transportation (CDOT). They may be supplemented ormodified to suit specific contracts.These specifications are expressed in United States Standard Measure (Englishunits). The international System of Units (SI, Modernized Metric) is used onlywhere standardized testing requires metric units. For clarity, aggregate sieve sizesappear in both SI and English Units. The dimensions, measurements, andrequirements stated in English units are the specification requirements. AllContractor submittals shall be prepared in English Units. Pay item quantities willbe measured in English units.Unless otherwise identified, forms herein referred to (e.g. Form 605) are CDOTforms. Forms from other organizations or agencies are clearly identified (e.g.FHWA Form 1273).Use of these specifications by any other organization or individual will be at theuser’s risk. Organizations or individuals citing these specifications by reference intheir contract work will be responsible for furnishing prospective bidders copies ofthe specifications along with any addenda that may affect their contract.Copies of this book may be obtained from the Colorado Department ofTransportation, Office of Bid Plans, 4201 E. Arkansas Avenue, Denver, CO 80222.Addenda to these specifications may be issued by the Department to suit its needs.Addenda may be accessed on the CDOT website and will be available for purchaseat prices established by the Department.iii
