Is your roller running out of water too often during the paving shift? When a spray nozzle is plugged or when the scraper bar is not held against the drum properly, you will get poor water coverage on the drum. It costs time to refill water tanks again and again. Letting the roller run with […]

If the lights in the control house dim when your plant manager presses the button to start production, you can bet you’re pulling a full load of amps. Whether he runs at full production or half the plant’s rated capacity, the burner, blowers, fans, cold feed belts, pumps, etc. are pulling maximum energy unless you […]

Contractors performing winter pavement maintenance should be clamoring for the jobs that service porous asphalt pavements. It would be irresponsible to say merely “you get to leave it alone,” but the fact is porous asphalt pavements require fewer deicing chemicals and less work than do impervious pavements. Here’s why. First, the Federal Highway Administration (FHWA) […]

Results of an industry-wide survey of 1,600 respondents conducted by the Associated General Contractors of America (AGC) and Autodesk this summer showed 70 percent of construction firms reporting difficulty in filling hourly craft positions. The positions represent the bulk of the construction workforce. The responses represent a labor drought the asphalt industry has become well […]

Let me begin this exposition on the asphalt industry’s use of asphalt cement (AC) and additives in environmentally positive configurations with a diversion. This diversion is toward the fantastic. Picture, if you will, a wasteland in which the missing windows of high rise buildings mimic broken teeth. Along litter-cluttered sidewalks, vines escape their cracked pots […]

If misalignment of the screed sections leaves a line in the mat, the roller operator is called on to smooth it out. Mat imperfections, divots, cool spots, anything that isn’t perfect gets left to the breakdown, intermediate and finish rollers to take care of.
