Abstract: In September of 2005, Hurricane Katrina devastated New Orleans and caused sustained flooding. Limited pre- and postflooding tests indicated that the pavement structures tested were adversely impacted by the flood water. ...

Abstract: In Louisiana, 50% of the districts use microsurfacing as a maintenance treatment with yearly expenditure of $4,700,000 (about 37% of overall budget allocated to pavement preservation) throughout the state as of 2016. Yet, ...

Abstract: Current pavement design procedures recommend the resilient modulus of subgrade materials for pavement design and analysis. The objective of this paper is to develop two statistical models to predict the resilient modulus ...

Abstract: The Rolling Wheel Deflectometer (RWD) offers the benefit to measure pavement deflection without causing any traffic interruption or compromising safety along the tested road segments. This paper presents a detailed field ...

Abstract: Using the rolling wheel deflectometer (RWD), which measures pavement deflections at traffic speeds, offers the potential to characterize the structural capacity of the road network without major delays and to do so in a ...

Abstract: Asphalt concrete stripping is a critical distress that occurs underneath the pavement surface due to the accumulation of moisture with no visual indication at the surface. Past studies have suggested the feasibility of ...

Abstract: Crack sealing of asphalt concrete (AC) overlays is an important component of pavement preventive maintenance. The objectives of this study were to evaluate the cost effectiveness (CE) of crack sealing applied on AC overlays ...

Abstract: Transportation agencies often need to differentiate between top-down and bottom-up cracking in the field to set up an effective and targeted schedule and budget for the repair of these cracks. The objective of this study ...
