Recently, diamond grinding has gained increasing attention as pavement preservation treatment to restore desired surface characteristics, particularly friction. Compared to other pavement preservation treatments such as surface overlays and high friction surface treatments, diamond grinding may cost less, save construction time, or require minimum...

Over the years, the Indiana Department of Transportation (INDOT) has changed its emphasis from construction to preservation of public highways. As such, there is great interest in assessing cost efficacy of a pavement preservation strategy. This paper aims to present the functional and structural benefits of microsurfacing applications at highway s...

This paper presents seal coat performance evaluations of various emulsion and aggregate application rates using three different evaluation methods: International Roughness Index (IRI), friction test, and visual evaluation. Then, considering the seal coat failure criteria, correction factors for seal coat application equipment are introduced. This s...

Subsurface drainage is important for long-term pavement performance. Rational procedures to analyze and evaluate the design, reliability, and effectiveness of subsurface drainage systems are needed in order for their use to be recommended with confidence. Three pavement subdrainage test sections were constructed in 1995 on the eastbound driving lan...

Accurate knowledge of pavement thickness is important information to have both at a network and project level. This information aids in pavement management and design. Much of the time this information is missing, out of date, or unknown for highway sections. Current technologies for determining pavement thickness are core drilling, falling weight...

Because of the evident advantages associated with the smooth tire for the measurement of pavement friction, many highway agencies have become interested in the smooth tire. Pavement friction is the result of tire-pavement interaction. Because of the differences between ribbed and smooth tires, experiences with the ribbed tire may not apply to the s...

Nondestructive testing has become an integral part of pavement evaluation and rehabilitation strategies in recent years. Pavement evaluation employing the falling-weight deflectometer (FWD) and ground-penetrating radar (GPR) can provide valuable information about pavement performance characteristics and be a very useful tool for project prioritizat...
