Here are some asphalt and road-building products in the news this year. Astec Inc. Astec Inc. earlier this year exhibited at the 2018 Intermat International Exhibition for Construction and Infrastructure in Paris. Attendees of Intermat 2018 learned more about the complete range of options available from Astec, including: •  The Double Barrel XHR, Astec's premium counter-flow aggregate drum dryer with an external asphalt mixer. An exclusive package of features on this drum can produce up to 400 tph of mix with up to 65 percent RAP/RAS content. • The Astec Warm Mix System, the latest generation simpli- fies production of warm mix asphalt. The benefits of warm mix asphalt, such as reduced energy consumption, lowered emissions and elimination of visible smoke, are well known in the asphalt paving industry. The Astec system achieves a lower temperature at a lower cost by eliminating the need for additives or special asphalt cement. Instead, the system injects a small amount of water into the liquid AC to create microscopic steam bubbles. These small bubbles act to reduce the viscosity of the liquid AC, allowing the mix to be worked at lower temperatures. • Astec Burners, the company offers the most technologi- cally advanced burners in the industry with the Phoenix and Whisper Jet burner lines. The Whisper Jet burner delivers unmatched reliability and hassle-free mainte- nance. It cleanly and efficiently burns oil or gas and has a compact flame. The Phoenix Talon burner sets the stan- dard for power and efficiency, while maintaining very low emissions. With the optional silencing package, it is quiet enough to have a phone conversation on the burner platform while it is firing. The Phoenix Fury burner is a great, cost-effective choice with a robust build and simple, accessible construction. Compared to other open-fired designs, the Fury burner achieves better emissions and fuel-efficiency by putting 50 percent more combustion air through the burner than competitive designs. The Phoenix Phantom Ultra Low NOx Premium burner leads the pack with the lowest available combustion and noise emissions (gaseous fuels only). The Phantom burner also achieves the highest electrical energy efficiency with innovations like variable speed drives and offers advanced mixing technology and the latest technological innovations to deliver the absolute minimum gaseous emissions avail - able today. •  The compact, highly portable Voyager 120 plant. Unique for a plant in this class is the ability to produce mix with up to 30 percent RAP content. Astec, CASE CASE Construction Equipment recently introduced the new SV212D and SV216D single drum vibratory compactors – compatible with both smooth and padfoot drums. With best-in-class centrifugal forces, self-adjusting torque control system and the most climbing power in the industry, these machines are built for industry-leading performance in the toughest applications. Able to climb grades of up to 65 percent, the SV212D and SV216D feature a low-center-of-gravity axle-free design and a high-traction hydrostatic drive system that provides On The Road Again Here Are Some of the Latest Road-Building Products Introduced This Year.
