Martin Marietta bid the job for each city separately, but when they were awarded both contracts they decided to combine the work and complete them as one job, according to Andrew Chaulk, project manager, Martin Marietta. The contractor milled 40,000 sq. yds 1 ½ in. thick of pavement and constructed a 2-in. overlay using 4400 tons of hot mix asphalt. “We looked at them as two separate projects and bid them accordingly,” Chaulk says. “Once we were awarded both contracts, we treated them as one job. It was a straightforward operation. A pretty standard job that went really well.”
The 2019 Larry H. Lemon Quality in Construction Award recognized Martin Marietta, Lakewood, CO, for its work involving more than 40,000 sq. yds. of milling and 4400 tons of paving on West Belleview Avenue, the dividing street between Colorado cities Lakewood and Denver.
The resulting work, which received a smoothness bonus, was named one of the 10 recipients of the National Asphalt Pavement Association’s (NAPA) 2019 Larry H. Lemon Quality in Construction Award for excellence in construction of an asphalt pavement utilizing less than 50,000 tons of asphalt.
