1. Type of Plant . There are two types of Asphalt Plants. Drum Mix and Batch. Notably, a batch plant is the best choice for an operation where the plant will be called upon to make various blend mixes in the same operational ‘run’, or if the plant will be doing a lot of starting and stopping in the course of the day.
Air Permits Division (APD) confirm that the proposed Hot Mix Asphalt plant meets the standard permit requirements. Please read all questions and check “YES,” “NO,” or “N/A,” or provide specific information for the facility. If the hot mix asphalt plant does not meet all conditions of this standard permit, it may not operate
PG 64-22 is the liquid asphalt (asphalt cement) that should be speciﬁed in most applications. Information on the Performance Grade (PG) asphalts may be found in PENNDOT’s Bulletin 25 (Publication 37), “Speciﬁcations for Bituminous Materials.” Information on plant requirements and mix
The Asphalt Materials section is AASHTO accredited and can perform all of the standard AASHTO and ASTM tests relating to asphalt mixes and asphalt binders. The section also conducts a variety of specialized tests including gyratory compaction, loaded wheel rut and fatigue, cracking, abson recovery, reflux and moisture damage tests.

modified asphalt are determined mainly by the base asphalt. The PPA generally provides improvements to the high temperature properties. For example, to meet a PG 64-28 specification, the base asphalt should meet a PG XX-28 specification. PPA Level Selection As is true with other asphalt additives, the amount of PPA required will be
2. The asphalt content is based on the total weight of the mix. When using slag aggregates in the mix, the asphalt content shall be increased accordingly, a minimum of 25 percent for an all slag mix. 3. Use a PG binder appropriate for the project location as specified in Table 6-4 of the Comprehensive Pavement Design Manual.
