Ongoing Research Project
Design of Microsurfacing with Reclaimed Asphalt Pavement (RAP) in Nevada
This research aims to investigate the utilization of 100% Reclaimed Asphalt Pavement (RAP) in the mixture designs for micro-surfacing applications. The use of RAP aligns with the principles of sustainable pavement engineering by reducing reliance on virgin aggregates. This study focuses on the identification of suitable RAP, characterization of their properties, and development of the mixture design methods for micro-surfacing conforming with the Nevada Department of Transportation (NDOT) specifications. To establish a comprehensive basis for mixture designs of microsurfacing utilizing RAP, materials were collected from eight diverse locations across Nevada and are now being used to design microsurfacing mixtures with two asphalt emulsions: a PMCQS-1h, typically used by NDOT, and a PMRQS, which includes a rejuvenator.
Undergraduate Research Project
Analyzing the Water Absorption Performances and Compressive Strength of PLC Concrete Using Water-Reducing Admixture.
The research aimed to develop water-resistant and sustainable concrete using a multitasking chemical admixture. Different dosages of the admixture were used, and two types of water absorption tests, with some characteristic experiments, were conducted to analyze and compare their performances with ordinary limestone concrete. Later, the study was extended by the co-researchers, and the paper was published in Materials Today Communications.
