Particulate emissions from the milling of reinforced road surfaces

The asphalt concrete used in this study is semi-grained asphalt concrete (BBSG). It has a grading of 0/10 and class 3 according to NF EN 13108-1. The binder is refined bitumen class 35/50 according to NF EN 12591.

At the Gustave Eiffel University center in Nantes, several pavement slabs* were built to standard NF P98-086 (2019) (figure 1). These differ according to the type of asphalt concrete used and the type of glass fiber added. Noted G1, G3, G4 and G5, the grids are composed of 17 µm-diameter type E glass fibers, resin and polyester fabric (figure 2). The fibers are bound together by a cross-linked butadiene latex. They are positioned...
