Current Texas Department of Transportation (TxDOT) procedures for evaluating coarse aggregate for portland cement concrete (PCC) have been in place for over 39 years. Item 421 in the TxDOT "Standard Specifications for ...

Concrete overlays have been a rehabilitation method for many years. It has been extensively utilized and studied in other states, but Texas is still at an initial stage of fully implementing the method. The large volume ...

Ultra-High Performance Concrete (UHPC) is an emerging material technology that exhibits a combination of high compressive strength, high tensile strength, high toughness and ductility, and improved durability when compared ...

Fifteen tests were conducted to evaluate the shear performance of beams with carbon fiber reinforced polymer (CFRP) laminates and CFRP anchors. The specimens consisted of 24-in. deep T-beams. The specimens were strengthened ...

Replacement of a percentage of cement by supplementary cementing materials (SCM) can control deleterious alkali-silica reaction. Silica fume, a commonly used SCM, and can be used to mitigate alkali-silica reaction (ASR). ...

Crucial part of the estimation of construction waste (CW) is a reliable quantification of the amounts of materials needed for building construction. In this research the use of Building Information Modeling (BIM) is proposed ...

This thesis presents an experimental study on the horizontal shear strength of reinforced concrete slabs and beams with unreinforced concrete-to-concrete interfaces. Current design provisions for new construction and repair ...

Highway air pollution is a significant environmental threat that has staggering implications for human health worldwide. Photocatalytic materials have the potential to reduce air pollution levels near major highways using ...

For repairing concrete transportation infrastructure, such as pavements and bridges, much importance is placed on early-age strength gain as this has a major impact on scheduling and opening to traffic. However, the long-term ...

This experimental program was focused on the effect of surface geometry (shear keys) on the transmission of shear forces between concrete cast against a hardened concrete interface. This research was part of a larger study ...
