l Specia : n Sectio NAPA s Award Larry H. Lemon Quality in Construction Awards High Scores, Smooth Rides Larry H. Lemon Quality in Construction Awards Honor Top-Performing Pavements By Mary Ann Melody T he path to winning a Larry H. Lemon Quality in Construction (QIC) Award for excellence in construction of an asphalt pavement is no simple feat. The pavements must meet certain specifications and achieve the required density - and then be the crème de le crème through the entire process of scrutiny and evaluation. The 2014 winners are recognized for having the 10 highest-scoring projects determined through a review by the National Center for Asphalt Technology. The projects were submitted to NAPA for a Quality in Construction Award in the General Paving (less than 50,000 tons) category. Each project submitted for a Quality in Construction Award is evaluated by NCAT engineers. The projects are given a numerical score based on the specifications and achieved density of the completed pavement. All pavements that earn a benchmark figure are selected for the QIC Award. The award is named after Larry H. Lemon of Haskell Lemon Construction Co. in Oklahoma City. Lemon served on the Awards Committee for 18 years, before becoming NAPA Chairman of the Board in 2010, prior to his retirement. Lemon was instrumental in the creation of the ratings system for the Quality in Construction Awards, which requires qualitative analysis using data and test results to determine the winners. The following is a brief synopsis of the 2014 winners of the Larry H. Lemon Quality in Construction Award. Bitters Road received a 0 .75-inch ultrathin bonded wearing course during the holiday season, with quick traffic return and minimal user delay. Clark Construction of Texas bitters Road in san antonio Clark Construction of Texas, based in San Antonio, won the award for its work on Bitters Road, located just north of San Antonio, from U.S. Route 281 West to Tomahawk Trail. The road configuration varies on this busy section of Bitters Road. It starts at U.S. 281 as a five-lane divided roadway with medians and becomes a four-lane highway with a continuous left-turn lane before finally ending as a four-lane undivided highway. The route contains retail businesses, restaurants, and entertainment venues. A 0.75-inch ultrathin bonded hot-mix wearing course was selected by the city of San Antonio, the road's owner. A membrane was applied first, within seconds to the laying of the mix, helping to seal the existing surface and provide optimal bonding of the ultrathin mix to the pavement. This continuous laying process allowed for quick traffic return and minimal user delay. The Class A trap rock included in the mix produced a durable macro-texture surface. The 0.75-inch mat optimized this trap rock, while also maintaining overhead clearances and curb exposure. 36 * View past issues online at continued on page 39
