Abstract: This paper summarizes the many variables that can affect the measured compressive strength of concrete cylinders. The paper includes the whole testing process: sampling, casting, initial curing, transporting, laboratory ...

Abstract: Layer coefficients of cement-stabilized soil were determined for use in the American Association of State Highway and Transportation Officials (AASHTO) pavement design method. The soils were an A-3 fine sand and an A-6 ...

Abstract: A study was undertaken to determine the drainability characteristics of several types of unbound granular materials that are used in pavement bases. From the literature, testing concerns were identified and analyzed. ...

Abstract: Some project specifications allow the substitution of compressive strength for flexural strength testing for the quality control of projects in which flexural strength is the critical type of strength, such as for pavements. ...

Abstract: Increased usage of reclaimed asphalt pavement (RAP) and reclaimed asphalt roofing shingles (RAS) in hot mix asphalt (HMA) has increased the need for recycling agents intended to return the age-hardened RAP/RAS binder ...

Abstract: A durability rating system is developed to assist in the classification of shale that is to be used in compacted embankments. The system is based on the loss of shear strength due to the intrusion of water. Nine different ...

Abstract: This paper describes an investigation into the causes of structural damage to a retirement home and the subsequent rehabilitation project. The investigation revealed that the damage was caused by shrinkage of the soils ...

Abstract: Current specifications require the removal of reinforcing bar contaminants that reduce bond prior to placing concrete. This study focused on the interactions of contaminant type, bar size, epoxy coating, concrete strength, ...
