Performance Graded Asphalt Products
Performance graded asphalt binders were developed by The Federal Highway Administration as part of the Super Pave research. McCall’s on-site modern lab insures these high industry standards are met or surpassed. We test each asphalt load that leaves our terminal. We run a complete analysis on every product we sell every week. Constant analysis and testing assures consistency in quality and value for all our customers.
Performance Graded Asphalt Products
PG64-22: The workhorse of the asphalt grades in Oregon and Washington. PG64-22 is used in public works projects as well as private commercial applications. This is the most popular grade of asphalt we sell.
PG58-22: This less viscous asphalt is used on the west side of the Cascades when you want a little extra time to work your mix. PG58-22 works well in the cooler months when extra time is needed for hand work. It also works well with higher RAP (recycled asphalt pavement) contents.
PG64-28: This is the asphalt grade of choice for most public works projects east of the Cascades range. PG64-28ER helps prevent thermal cracking in colder climates and with a bit higher viscosity PG64-28ER is rut resistant.
PG70-22: This higher viscosity asphalt is used in high volume traffic areas with heavy loads. ODOT will call for PG70-22ER in some of its level 4 mixes. PG70-22ER has characteristics that help prevent rutting and cracking. Agencies prefer PG70-22ER at intersections where there are slow moving heavy loads.
PG70-28: This polymer modified asphalt is used in many level 4 asphalt mixes all around the region. This heavy duty asphalt resist rutting and cracking in very cold climates and in heavy traffic areas with heavy and excessive static loads.
Elastic Recovery: Most of our asphalts can be made to meet the Elastic Recovery specification. State DOT’s and other agencies will require an Elastic Recovery specification in areas they believe warrant an extra tough asphalt mix. Agencies call for Elastic Recovery asphalt on our interstate system and in higher elevations with extreme temperature fluctuations.
