Pavement maintenance and repair is a crucial part of pavement management systems. Accurate reliable performance prediction the prerequisite for making reasonable decisions selecting suitable schemes. Rutting deformation, as one most common forms asphalt failures, key index evaluating performance. To ensure accuracy commonly used models, input parameters models need to be understood, coefficient...

One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. During the last two decades Wisconsin Department of Transportation has made significant steps in improving material properties, design practices, and monitoring of pavement performance. The databases that are ava...

Reclaimed asphalt pavement (RAP) has been widely used in pavement. However, the fatigue performance of hot-mix (HMA) with RAP is a critical factor to ensure durability. In this study, tests using an Overlay Tester (OT) were conducted novel load-controlled mode. contents 0, 25% and 50%, respectively. cyclic loading, life energy parameters measured. Results indicated that decreased both fracture ...

Abstract Some of the factors causing early damage to Indonesia’s flexible pavement system in Indonesia were allegedly caused by several things, including Equivalent axle load (EAL) equation incompatible with situation where most heavy vehicles carry overloaded loads. One effort that can be done avoid severe road is overlaid pavement. It suspected overlay on will affect shape EAL equation. This ...

Bond strength between two layers of hot mix asphalt (HMA) pavement is a major issue. Poor bond may be attributed to the premature fatigue failure, top down cracking, slippage cracks in the surface layer, and also difficulty in compaction due to insufficient shear strength. A thin and uniform application of emulsified asphalt or tack coat ensures a good bond between the existing surface and the ...

an experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. the objectives of this study were to asses the effects of geosynthetics inclusion and its placement location on the accumulation of permanent deformation. to simulate an asphalt pavement overlaid on top of a crack in a concrete or asphalt pavement, ...
