Status of Thin-bonded Concrete Overlays


Book Description

The Demonstration Projects Division of the Federal Highway Administration has been involved in the evaluation of a number of thin-bonded overlays since 1979. This report presents the status of those projects and includes a summary of some of the more important findings to date.







Thin and Ultra-thin Whitetopping


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.



















EXPERIMENTAL ANALYSIS OF WHITE TOPPING BETWEEN ROADS IN SAGAR


Book Description

White topping is a rehabilitation method for moderately distressed hot mix asphalt (HMA) pavements by plain concrete (PC) or fiber reinforced concrete (FRC) overlay. White topping is constructed with thinner and shorter slabs. The structural stiffness of the existing HMA layer and the interface bonding between the concrete and HMA layers are accounted for in the mechanistic design procedure. This results in the need for a thinner concrete slab. The main advantage of this type of overlay over the traditional HMA overlays is the use of the underlying HMA layer to carry the traffic load, and thus reducing the thickness of the overlay.
