Mitigating Clay Contamination In Field Sands To Prevent Early Age Failure In Asphalt Mixtures, Suhail Rashid Vaid
Open Access Theses & Dissertations
Field sands are commonly incorporated into hot mix asphalt (HMA) pavements due to their availability and cost-effectiveness compared to crushed aggregates, primarily to enhance workability. Their usage, however, is generally restricted to no more than 10% of the total aggregate content because of concerns regarding their potential negative influence on pavement performance. A major concern is the presence of deleterious clay particles, which can substantially affect the behavior of asphalt concrete (AC). This research explored how clay minerals influence AC performance by examining Superpave mixtures and characterizing both clay and sand properties. The methylene blue value (MBV) was employed to …

A Two-Stage Direct Integration Approach To Find The Railway Track Profile Using In-Service Trains, Yifei Ren, Jennifer Kennahan, Eugene O'Brien
Civil Engineering Research in Ireland 2020
The railway track is an important element in transportation networks. In recent years, drive-by monitoring of railways has become more popular. Using data measured from in-service trains, the railway profile can be found. In previous research, a complex optimiziton method is used to calculate the railway profile. This paper introduces a new two-stage direct integration approach to find the same track profile much more efficiently. The calculated track profile is similar to a ‘true’ profile and can be used to monitor the condition of the track.
