A Solution to Joint Density Failure: J-Band + Rapid Penetrating Emulsion (RPE)

J-Band
Achieving adequate density at the longitudinal joint of a road is challenging. Well-constructed joints typically have 1-2% lower density than the mat, while poorly constructed joints can be 5-10% lower. When the density at the joint is considerably less than that of the mat, the joint area has more air...
