Efficient sealcoating claimed by Neal Manufacturing

Neal Manufacturing is introducing a new sealcoating baffle attachment that is said to boost efficiency. A division of Blastcrete Equipment, Neal Manufacturing has designed its DA 350 Dual Applicator so that it can be retrofitted onto any truck-powered sealcoating unit. The piece of equipment can be used to automatically cut-in sealcoat materials on the go, while keeping curbs and edges free of material.

Neal Manufacturing is introducing a new sealcoating baffle attachment that is said to boost efficiency.

A division of 2647 Blastcrete Equipment, Neal Manufacturing has designed its DA 350 Dual Applicator so that it can be retrofitted onto any truck-powered sealcoating unit. The piece of equipment can be used to automatically cut-in sealcoat materials on the go, while keeping curbs and edges free of material. The unit can be paired with Neal’s high-powered blower to further increase sealcoat preparation productivity. 

The firm says it designed the hydraulic AutoTrim to address the time-consuming, manual task of cutting in, as well as to improve the sealcoating process. The hydraulic AutoTrim features a spray nozzle, hose and baffle that bolts to the front of the machine and connects directly to the applicator’s sealcoat reservoir. The system reduces manpower which means there is no need for an operator to hold a baffle and spraying material. Combined with Neal’s blower, contractors can clear debris with the blower and cut in with sealcoating materials as fast as 4.26m/s, seven times faster than with manual tools.

The DA 350’s hydraulic blower triples the output of a walk-behind blower and contractors can rotate the unit for transportation or operation. The nozzle on the blower articulates 360°. Neal’s DA 350 Dual Applicator is a three-wheeled, self-propelled sealcoating machine that features a 1,325litre tank and allows contractors to apply sealcoat with squeegee and spray systems.

The heavy-duty squeegee assembly has internal baffles that help distribute material more evenly. After applying a coat with the squeegee, contractors can apply a second coat with the DA 350’s spray bar, which can expand up to 3.66m wide. A spray coat also can be applied with a 1.83m hand wand and 22.86m of reinforced hose for added versatility. Neal’s dual application system allows contractors to fill voids in the asphalt surface using the squeegee. They can then apply a second coat with the spray bar for a smooth finish that lasts up to 40% longer than a job done with two spray coats.

The control panel allows users to access all electrical controls from one location, while the machine has LED working lights at the front and back for night-time working. The DA 350’s heavy-duty aggregate pump is hydraulic-powered and can transfer up to 378litres material/minute.

The load-sensing HDP produces enough pressure to pump modified sealers, emulsions and mastics for asphalt roads, as well as mixes with high sand content. The DA 350 can be powered by a 28kW Kohler petrol engine, or a 26kW Kubota diesel.

    A major job for micro surfacing took place on the Brooklyn Bridge near New York. It was the third time in Ken Messina’s career that he would provide micro surfacing for the iconic Brooklyn Bridge, built in 1883. Messina, as president of New Jersey-based Asphalt Paving Systems (APS), knew only too well the challenges that lay ahead. And there were many. There would be only a brief window of opportunity for paving, with lane closures starting at 10pm and ending at 5am. The cool, humid atmosphere would a

    With the asphalt paving segment split broadly into two methods, American or European,. it is no surprise that manufacturers. from these countries have dominated the market for some years. An interesting development in recent times has been seen with various European firms developing asphalt pavers to suit North American needs, including BOMAG, Dynapac and Vögele. Caterpillar and Volvo by comparison both offer both European and US-style pavers, with separate model ranges that have been developed over many ye

Mike Woof reports The recent increases in oil costs are having a knock-on effect for the road construction sector, as asphalt prices have increased noticeably and faster than those for concrete. This has spurred renewed discussion over which construction technique now offers the best long term solution for road building. The debate between those in favour of concrete and those preferring asphalt for highway construction has been on

  • High performance, high mobility of wheeled pavers
    February 14, 2012
    New generation wheeled pavers aimed at use in territories such as the UK, Italy, South Africa and Southern Germany are now coming to market. Pavers in these countries are often expected to be driven from one part of a site to another or for short distances, which is why the additional mobility of the wheeled machine is preferred in many instances over similarly-sized tracked models. This preference for wheeled units comes in spite of the greater stability offered by tracked machines. BOMAG, Caterpillar and
