E.J. Breneman's cold-in-place recycling train is led by a 4500-gallon tanker carrying emulsified asphalt. Next is a down-cutting Caterpillar 750C milling machine, which creates a 2-inch-minus material and mixes it with 2% emulsion by weight. The material is conveyed into a windrow elevator, which lifts it into the payer in the rear. Compaction and an overlay follow. Photo: E.J. Breneman
