Road Construction Products Boral Road Materials offer cost-effective alternatives and performance advantages to conventional road and highway construction and repair materials. We have more than 40 years of experience working with coal combustion products (CCPs) from coal-fired power generating plants to develop products targeted to road applications. In addition, we have participated in numerous industry studies and various DOT research projects concerning materials for road stabilization and construction. The following is a summary of the Road Materials we offer: • Boral RoadMix Base™ This combination of bottom ash and pelletized high calcium fly ash is produced in a patented process using a MACS® machine. RoadMix Base provides high durability as a semi-rigid, non-plastic road base material. Its stability also makes RoadMix Base very effective in certain fills and beneath construction slabs. • Boral Intrix™ BMTI worked with the National Center for Asphalt Technology during rigorous testing of fly ash as mineral filler in Stone Matrix Asphalt (SMA). As a result, Intrix meets specifications for pavement design and is now being used in SMA projects. Intrix plays a crucial role in SMA by filling voids and achieving the desired stiffness in the asphalt. • Boral MACS-ASH® This pelletized high calcium fly ash is an alternative to Durabase for roadbed stabilization and waste stabilization projects where dust reduction is of paramount concern. • Boral Durabase™ Durabase is a product of more than 20 years of BMTI experience in using high calcium fly ash for both roadbed and waste stabilization projects. Contractors can call on our extensive experience for help in properly utilizing Durabase in specific applications.
