Evaluation of causes of excessive settlements of pavements behind bridge abutments and their remedies - phase I progress report no. 1 (84-12-2)
(1986-1)
Bridge approach settlement problem is quite extensive in the
U.S.A. This problem has been investigated since early 1960s, but
no satisfactory solution has been achieved. A comprehensive
literature search has been carried ...

Six most commonly encountered aggregate materials which are used ´ subbaseslbales in Oklahoma are se1ected and tested under dynamic loading by using AASHTO designation T292‡91 I. A ‡ vibratory compaction method was ...
Expert systems applications for ODOT (FHWA-OK-91-09)
(1991-7)
Expert systems are "intelligent" computer programs which have the capabilities of reasoning, learning, and simulating human sensory capabilities. Solutions to many problems in transportation engineering which are not well ...
FEABAS A user friendly software for prediction of bridge approach settlement (FHWA-OK-95-03) 2188
(1995-5)
Bridge approach settlement is a major problem in highway design as well as maintenance. It creates an unsafe and uncomfortable riding surface. This report presents the details of a software that was developed at the ...
Assessment of resilient modulus testing methods and their application to design of pavements (FHWA-OK-91-08)
(1991-6)
Resilient modulus (RM) is an important property of subgrade soils that accounts for repetitive loads due to vehicular traffic. Since AASHTO recommended its use in pavement design in 1986, various transportation agencies ...
