The workshop covered many aspects of asphalt pavements, including significant changes to the P-401 spec that were made in the recently released AC 150/5370-10H. Day 1 topics included an overview of the workshop, aggregates, asphalt binder, hot-mix asphalt mix design and contractor quality control program.
Samples obtained by plate sampling are tested to determine the gradation and binder content of the asphalt concrete mix. In addition to plant sampling and verification for acceptance the specifications require density gauge testing according to Supplement 1055 when placing a uniform course 1 inch or thicker.
The asphalt mixing plant shall be capable of producing a uniform material, have adequate capacity, and be maintained in good mechanical condition. Defective parts shall be replaced or repaired immediately if they adversely affect the proper functioning of the plant or plant units, or adversely affect the quality of the hot asphalt plant mix.
STATIONARY ASPHALT MIXING PLANTS | 11 ///// ///// // MIXER The mixer is the key component of an asphalt mixing plant. Here, the mineral is mixed intensively with binder and filler to form a homogeneous mass. A mixing cycle, including the filling and emptying, takes 45 seconds. Due to the heavy burden with regard to wear, weight and

The melt-in material and trowelable cover mix cost about 0 for a typical driveway. It’ll take almost a full day to repair several cracks if they’re 20 ft. long or so, but the asphalt repair work will last much longer than other quick fixes.
The Asphalt Institute’s manual on asphalt hot mix recycling also provides trial mix design examples that indicate how to use a viscosity blending chart to design a recycled hot mix. The Asphalt Institute suggests that when 20 percent or less RAP is used in a mix, no change in asphalt grade is required.
Parallel-Flow Drum-Mix Plants This section is concerned with the processing of aggre gate and asphalt cement in a parallel-flow drum-mix plant. The methods used to introduce the aggregate into the drum are first reviewed, followed by the operation of the burner system and the three-step heating, drying,

total mix weight. The target asphalt content is based on design and field Marshall mix test results. The target asphalt content may be adjusted to improve mix properties as measured by field Marshall tests. Maintain the actual asphalt content in the mix within plus or minus 0.3 percent of the target asphalt content.
The function of the hot mix plant is to heat the aggregates, add the asphalt cement and produce a homogenous asphalt mixture. The aggregate used to make the mix can be a single aggregate, but it is generally different sizes blended together through the cold feed bins to produce proper gradation.

The positive performance of modified asphalts is commonly recognized and demonstrated by lab testing, but there has been little available documentation of improved field performance. A study undertaken by the Asphalt Institute cited here is an example of one effort to document the performance benefits.
