ASTM International has released a standard to help government agencies select the best hot-applied asphaltic materials to repair potholes and cracks in asphalt and hydraulic-concrete pavements.
ASTM International member Saleh Yousefi, says hot-poured aggregate filled mastic is a combination of aggregate and modified asphalt used to fill potholes, wide cracks, and other distress in pavements. Different climates need this material to have specific properties and performance.
“The new standard will help agencies and contractors choose the right product grade for a specific job based on its climate. This will help increase the treatment’s service life, the pavement’s life, and could eventually save agencies a significant amount of money,” Yousefi adds.
ASTM says pavement distresses which can be treated by hot-poured asphalt can include wide cracks not suitable for crack sealing, corner breaks and other small repairs which do not require remove and replace procedures.
ASTM International’s road and paving materials committee (D04) developed the new standard, which is to be published as D8260.
