12 December 2014 Better Roads W e receive hundreds of new product submissions each year. After care- ful refl ection on the products covered and submitted both online and in print this year, these are the ones that most caught Better Roads' editors collective eye for their industry signifi cance, their ingenuity, their fi lling of a market need and/or their just plain ol' coolness. This wide, innovative range of new equipment and products for the bridge and road construction and maintenance sectors ran in the print edition of Better Roads or to serve contractors and agencies. Making this list is diffi cult. This is a short list, and it may not match yours. Some of it is subjective, but it is a way for us to acknowledge some of the industry leaders, some of the companies, some of the engineers and designers who did something special to bring the industry outstanding products. We'd love to hear from you what's on your list. Let us know at Better Roads 2014 Top RollOuts Better Roads' editors choose the year's top 25 products. Blacklidge Emulsions Trackless Tack Blacklidge Emulsions' HTSS-1 HM Emulsion Trackless Tack is an advanced asphalt emulsion tack specially formulated to dry extremely fast into a hard and drive-able coating – often in less than 10 minutes after applica- tion. Recent national studies indicate that Trackless Tack, when compared to traditional tack coats, can help contractors achieve better density with less compactive effort and improves the bonding and shear strength between two asphalt pavements. Additionally, saving 20 minutes per crew per day can save more than $150,000 this year. In most conditions, the tack is ready to pave in less than 10 minutes. Traditional tack coats are regularly tracked away from the job site resulting in unsightly track marks. In addition, reduction of application rate between pavements can occur, which could cause poor performance in the wheel path and will lead to expensive clean up. Doosan fuel-effi cient artic dump trucks With the 365-net-horsepower DA30-5 and 490-net-horsepower DA40-5, Doosan's two new articulated dump trucks launched this year feature fuel- effi cient Scania DC9 and DC13 engines, respectively. The 51,588-pound DA30-5 has a 61,729-pound payload rating with a 23.3-cubic-yard heaped capacity, 9-foot, 10-inch loading height and a maximum speed of 36 mph. The 71,107-pound DA40-5 has a payload rating of 88,185 pounds, a 34-cubic-yard heaped capacity, a 10-foot, 8-inch loading height and maximum speed of 33 mph. The trucks are confi gured with a high-pressure common-rail fuel delivery system, cooled exhaust gas recirculation, selective catalyst reduction and a diesel oxidation catalyst, the 28- and 40-metric-ton weight class trucks use diesel exhaust fl uid injected into the exhaust system to transform NOx into water and nitrogen.
