Document: 

SP51-01

Date: 

January 1, 1975

Author(s):

E. Guy Robbins

Publication:

Symposium Papers

Volume:

51

Abstract:

Knowledge gained from slipforming heavy-duty concrete airport and primary road pavements has been applied to slipforming thin-concrete pavements for secondary and county roads carrying low volumes and light weights of traffic. Studies show that at low volumes of traffic there are few heavy multiaxle trucks in the traffic stream.

Abstract:

With increases in revenues not keeping pace with the demand for more and safer roads Engineers at the Macomb County Road Commission sharpened their pencils and tailored their concrete pavements to meet individual project needs. Weighing maintenance problems and evaluating performance on existing pavements in the area, current pavement design practices were modified to reflect local experience and a bold and economical design was evolved.

Abstract:

A presentation explaining the problem of Michigan county engineers in road construction. . .This presentation explains the procedure followed by a subcommittee of the Michigan County Road Association in attempting to providde a design procedure that would correlate concrete and asphalt designs, utilize local materials, all with reasonable controls and costs. The results - the first printing of the "Road Design Manual" and the start of a common design language.

Abstract:

The finite element method is used to determine the stresses and deflections in rigid pavement slabs of finite size, for both central and edge loading conditions. The main variables considered are the thickness of the slab, the modulus of elasticity of the subgrade, and the values of the load and tire pressure.
