“…It was found that the transition areas or ends of whitetopping pavements are typically in severely deteriorated condition, likely due to the impact by vehicles, as compared to the rest of pavement. This was also reported in other studies (Wu 2007). Therefore, when determining the PCI or PDI, the short whitetopping pavements were at a disadvantage when compared to longer projects.…”

“…At the transition areas (between UTW pavement and other types of pavement), there is a need for thicker slabs between the UTW applications and the asphalt roadways. This was recommended in the ACPA design guide (2002) and supported by field observations (Wu et al 2007).…”

“…Rasmussen (2004) reported that aggregate thermal properties (coefficient of thermal expansion (CTE), thermal conductivity, and specific heat) and aggregate gradation needed to be considered in the concrete mix design. The CTE is of interest considering that the literature shows that there is a significant increase in the stresses in the WT layer due to the thermal gradients (Roessler 1998; Kumara et al 2003;Lin and Wang 2005;and Wu et al 2007).…”

“…It is not known how this behavior influences the performance of whitetopping pavement. In the literature review (Cole 1997;Vandenbossche 2003;and Wu et al 2007), corner cracking is reported to be the most commonly observed structural distress. Figure 4, a picture taken from the FHWA ALF UTW study , is an example of the distress.…”

Whitetopping overlay is a concrete overlay on the prepared existing hot mix asphalt (HMA) pavement to improve both the structural and functional capability. It's a relatively new rehabilitation technology for deteriorated HMA. If the slab thickness is less or equal to 4 in., it is referred to as ultra-thin whitetopping (UTW). "WT" is used to refer to concrete overlay thicker than 4 in. In this research, the term "whitetopping" is used to refer to both WT and UTW in general. The primary objectives of this study are to catalog the whitetopping (WT) and UTW projects in Wisconsin, document pertinent design and construction elements, assess performance and estimate a service life of these projects. A comprehensive literature review was performed. A database of the WT and UTW projects was established covering 18 projects built from 1995 to 2007 in Wisconsin. The performance of these WT and UWT projects were assessed, by mean of shear strength tests on field cores, falling weight deflectometer (FWD) tests on selected projects, and field distress survey on in-service projects. FWD backcalculation methods for WT and UTW pavements were studied and a Critical Distance Method was proposed and utilized for UTW pavement. Fatigue life was analyzed using 18kip, 22kip and 26kip single axle load level. Performance assessment was conducted using both Pavement Condition Index (PCI) and Pavement Distress Index (PDI). The performance of whitetopping projects in Wisconsin was found comparable to that in other states. Whitetopping overlay thickness, joint spacing and pavement age were found to have significant effects on pavement performance.

“…Este método é mundialmente conhecido como "whitetopping" e vale-se da grande resistência a compressão e abrasão do concreto, ampliando a sobrevida das vias com a mínima manutenção. Este processo já é utilizado a mais de um quarto de século pelo departamento de rodagens de Nebrasca (USA) e, com o passar do tempo, em todo mundo (LIN, 2005;REA, 2005;WU 2007).…”

As rodovias sÃ£o as principais formas de transporte do Brasil e, portanto, necessitam de pavimentaÃ§Ã£o de alta durabilidade e baixo custo de manutenÃ§Ã£o capazes de suportar o trÃ¡fego intenso, pesado e repetitivo. A pavimentaÃ§Ã£o asfÃ¡ltica Ã© o principal modal de pavimentaÃ§Ã£o moderna presente e, no entanto, deve proporcionar comodidade e condiÃ§Ãµes ideais de trafegabilidade; em funÃ§Ã£o disso, o aparecimento de patologias gera transtornos e reduz o seu tempo de vida. Patologias sÃ£o ocasionadas por diversos fatores, erro de projeto, intempÃ©ries, falta de manutenÃ§Ã£o, dentre outros. Neste trabalho, Ã© apresentado o estado da superfÃcie do pavimento das principais vias que cortam a cidade de Santa Margarida-MG divididas em 4 trechos. Foram levantadas as patologias apresentadas nessas vias por meio de procedimentos baseados em normas vigentes no Brasil, com o objetivo de, em primeira instÃ¢ncia, analisar e indicar as devidas causas e, em seguida, indicando formas de prevenÃ§Ã£o ou correÃ§Ã£o. Foi constatado que as vias em estudo apresentam patologia principalmente ocasionadas em maior parte pelo fim do ciclo de vida do pavimento ocasionada pela fadiga, trÃ¡fico repetitivo de veÃculos pesados e, em alguns casos, com auxÃlio de infiltraÃ§Ãµes e intempÃ©ries causando a delaminaÃ§Ã£o do asfalto entre ele e entre o leito.
