Paul Lum, Marketing Manager LafargeHolcim now presenting in best practices and QC for recycled aggregates. #OGRAROMA

Lum - objective is to produce granular road base materials meeting OPSS 1010 requirements. #OGRAROMA

Lum - Best use of recycled asphalt is in hot mix, but low % regulations means high stockpiles. #OGRAROMA
