Abstract: Seventeen major companies involved in the engineering and construction (E&C) industry (eight owners and nine contractors) were interviewed. The companies were selected based on their known successful implementation of total ...

Abstract: Selected physical properties of asphalt cement are significantly changed by artificial aging under thin film oven test conditions. The changes in physical properties are also reflected in the molecular size distribution ...

Abstract: Long-term age-hardening behavior of asphalt cements was simulated by the thin-film-oven test procedure with extended oven durations. Seven AC-20 asphalt cements from different crude sources were aged for 5, 14, and 24 h. ...

Abstract: A procedure for defining the appropriate relative quantity for the large molecular size (LMS) fraction in asphalt was developed based on the correlation between chromatogram and selected physical properties. The physical ...

Abstract: This paper presents an experimental analysis of the relationship between the relative quantity of a particular‐size molecule in asphalt cement and the mechanical properties of asphalt concrete. Three AC‐20 grade asphalt ...

Abstract: Several troublesome challenges face the U.S. construction industry: productivity is down, litigation is up, delays are common and expensive, foreign firms are taking a greater share of the market. The reasons are complex, ...

Abstract: To address quality problems and their associated costs, the construction industry must pursue and implement innovative quality‐management organizations and techniques. This paper presents the findings of a research project ...

Abstract: To address quality problems and associated costs, the construction industry must pursue and implement innovative quality management organization and techniques. The need for quality management in the construction industry ...

Abstract: Quality deviation data are collected from nine fast‐track industrial construction projects. The data are collected after the construction phase of the projects and identify the direct costs associated with rework (including ...

Abstract: Acceptance of asphalt pavements on a lot basis depends on how well the material conforms to specified quality characteristics. If a lot does not fall within the specified tolerance limits for a given characteristic, the ...
