  • UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION
    UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION SPONSORED and DISTRIBUTED by the 1998 ARIZONA (Includes revisions through 2010) FOREWORD Publication of these Uniform Standard Specifications and Details for Public Works Construction fulfills the goal of a group of agencies who joined forces in 1966 to produce such a set of documents. Subsequently, in the interest of promoting county-wide acceptance and use of these standards and details, the Maricopa Association of Governments accepted their sponsorship and the responsibility of keeping them current and viable. These specifications and details, representing the best professional thinking of representatives of several Public Works Departments, reviewed and refined by members of the construction industry, were written to fulfill the need for uniform rules governing public works construction performed for Maricopa County and the various cities and public agencies in the county. It further fulfills the need for adequate standards by the smaller communities and agencies who could not afford to promulgate such standards for themselves. A uniform set of specifications and details, updated and embracing the most modern materials and construction techniques will redound to the benefit of the public and the private contracting industry. Uniform specifications and details will eliminate conflicts and confusion, lower construction costs, and encourage more competitive bidding by private contractors. The Uniform Standard Specifications and Details for Public Works Construction will be revised periodically and reprinted to reflect advanced thinking and the changing technology of the construction industry. To this end a Specifications and Details Committee has been established as a permanent organization to continually study and recommend changes to the Specifications and Details.

To Improve the existing CBR pro­ other factors that affect the stability of pavement during 1928 cedures, an alternative method has been employed successfully and 1929. The study indicated that pavement failures could be to obtain CBR-values of soil and to evaluate the moisture ·. traced directly to poor compaction during construction or was susceptibility of soils. This method is not only easier to perform brought about by insufficient thickness of pavement and by the but also requires less effort because only four samples need be existence of a base course over soils inherently weak in shear compacted and tested. There are also fewer sources of error in strength. Therefore a static field load test was first tried for that obtaining the "correct" optimum moisture content for compaction is not required because the test Is considered an establishing the density that should be used in the construction extension of the compaction tests (i.e., AASHTO T99 and of subgrades and the shear strength that was required.

  • California Bearing Ratio (CBR)
    California Bearing Ratio (CBR) • California Bearing Ratio (CBR) is a penetration test for evaluation of the mechanical strength of road subgrades, sub-base and base courses. It was developed by the California Department of Transportation. • The test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. The measured pressure is then divided by the pressure required to achieve an equal penetration on a standard crushed rock material. or • The test is performed by measuring the load required to penetrate a soil sample with a plunger of standard area. The measured load is then divided by the load required to achieve an equal penetration on a standard crushed rock material. California Bearing Ratio = (Load required for a certain penetration of plunger) x 100 Standard Load for same penetration • Surcharge plates are used on the mould to simulate the field conditions One surcharge plate represents 2.5” thick pavement Two surcharge plates represent 5” thick pavement CBR0.1” = Load required for 0.1” penetration of plunger (lb.) 3000 CBR0.2” = Load required for 0.2” penetration of plunger (lb.) 4500 •Higher of the two values will be used for design •Usually CBR0.1” > CBR0.2” Pavement Design California Bearing Ratio (CBR) “The Test” Take load readings at different penetrations 0.025” ……………70 psi 0.05”……………...130 psi 0.1”……………….220 psi 0.2”……………….300 psi 0.4”……………….320 psi 6” mold Penetrations of 0.05” per minute Achieve OMC & Max.
