HOT MIX ASPHALT CONSTRUCTION--FIELD DIAGNOSIS AND TROUBLESHOOTING GUIDE (WITH DISCUSSION)

The quality of construction markedly affects pavement performance. Cracks built into the pavement, low spots in the mat where water can collect, segregation, poor joints and other defects all contribute to a deterioration of the hot mix asphalt (HMA) layer. Furthermore, if the required density levels are not achieved, the mix may deform, it may be more susceptible to moisture, the asphalt cement can harden prematurely, fatigue resistance will decrease, and its structural strength contribution will be reduced. In addition to these engineering considerations, pavement smoothness is important because it affects the total transportation costs incurred by the road user. This paper translates field and laboratory experience into a format which will readily assist field diagnosis of mat deficiencies and reduce the incidence of built-in defects.
