Trr No. 1171 Asphalt Materials And Mixtures, pp. 66-70 The purpose of this paper is to present some of the ways the research team solved the major difficulties encountered with the implementation of the test. Several aspects of the test procedure are analyzed: method used for asphaltene precipitation, filtration, solvent concentration and some problems related to the use of alumina and the chr…
The query refers to a road rehabilitation project on Highway 20 in California that utilized the Wirtgen WR 2500 cold recycler machine for a cold foam in-place recycling application. The "WR 2500" is the model number of the machinery used, not a formal project name itself. This project was a demonstration or a specific job that showcased the cold recycling technology using foamed bitumen as a bi…

Nondestructive evaluation of pavement performance by methods such as the Falling Weight Deflectometer (FWD) are widely used and accepted. Backcalculation and prediction of pavement layer moduli can be effective for both the evaluation of pavement condition and overlay design. However, variations in pavement temperature and subgrade moisture content result in variability in the backcalculated mo…
