An important decision for District Engineers is to determine the most efficient assignment of routine maintenance projects to either State forces or p...
As part of a project with the Iowa Department of Transportation to develop a set of standards for single span prefabricated bridges in the 30' - 70'...
This project examined the use of the light weight deflectometer (LWD) and the air permeameter test (APT) for control of the state of compaction and hy...
This study evaluates the practices and costs of mowing, litter pickup, and herbicide spraying maintenance functions. Data are collected to determine t...
This study analyzes grade separated ramps serving frontage roads to investigate operational and geometric requirements, to prepare guidelines on benef...
The deformational characteristics of various soils at small (.00001 to .001%) to intermediate (.001 to .1%) shearing strains using resonant column and...
The 1986 AASHTO Guide for Design of Pavement Structures incorporates the resilient modulus of pavements into the procedure. This parameter is analogou...
This report contains a critical evaluation of the resilient modulus testing procedure based on more than 200 tests. The state-of-the-art for obtaining...
This report contains the appendices and supporting data for the project report. The project report contains a critical evaluation of the resilient mod...
The main objective of this study is to investigate the importance of depth to bedrock in surface loading tests. Two surface loading tests, the Dynafle...
In this research study, Spectral-Analysis-of-Surface-Waves (SASW), Falling Weight Deflectometer (FWD), and compression wave (P-wave) tests were employ...
Falling-Weight Deflectometer data from three in-service pavement sections have been used to analyze dynamic response characteristics. The analyzed dat...
Results of computations of pavement layer properties are presented for 24 Texas asphaltic concrete (AC) pavement sections. Layer properties were compu...
This report summarizes the results and conclusions of a five-year study of the effectiveness of vertical moisture barriers in controlling the roughnes...
Most multipath assignment techniques are generated based on either path enumeration or path diversion. Path enumeration models primarily reiterate the...
