This study was conducted to develop a uniform set; of standard specifications covering underground utilities for cities, counties, and other public agencies in the State of Minnesota.
In the past it has been the practice throughout the State of Minnesota that each of the governing bodies have their own individual specifications for public works. This has caused confusion, inconvenience and increased costs to consultants, material suppliers, contractors and the public officials. It also resulted in static specifications even though major advances have been made in the public works field.
This specification is the cumulative result of the input of specifications from many sources. The sources included, but were not limited to municipalities and consultant organizations, the American Public Works Association, and many working specifications in use throughout the country. To insure the workability of the final specifications, meetings were held with inspectors, foremen, and engineers who were employed in the field of underground utilities.
It Is assumed the general conditions of the governing agency will be used in conjunction with these specifications. In the future, statewide general conditions may be published
This study was conducted to determine the construction feasibility and the requirements that are needed for a roadbed which would meet the increased demands of traffic volumes and loads that are to be expected in the future. To accomplish this the construction of a portland cement concrete pavement over bituminous-treated and cement-treated bases was monitored and certain tests which supposedly relate to long-term performance were conducted. Standard granular base sections were also included for comparison purposes.
