Performance of Paving Fabric Reinforced Asphalt Mixture
The paving fabrics as interlayers have been used in asphalt overlays in a variety of design and construction situations for more than three decades. A number of positive benefits have been identified such as waterproofing control for base and subgrade protection, improved fatigue resistance, and reduced reflection of existing cracks, etc. In cold regions such as Alaska and other northern states, pavements are more prone to distresses due to extreme climatic conditions. A study has been conducted to explore how paving interlayers function in asphalt pavements in Alaska. This paper presents laboratory investigation of performance of asphalt mixtures reinforced with three types of paving fabrics. These three types of paving fabrics included two biaxial fabrics (i.e. PGM-G100/100 and PGM-G50/50) and one newly developed, multi-axial, reinforced paving composite, PGM-G4. The performance tests included asphalt retention, grab strength, shear strength, permeability, and indirect tension (IDT). The results showed that adding paving fabric can increase pavement structure stiffness, greatly reduce the permeability and also provide good resistance to low temperature cracking. The multi-axial PGM-G4 paving composite provided the best overall pavement performance.
