In 2019, an airfield improvement project was completed to rehabilitate the existing asphalt surface of Runway 5/23. The project consisted of pavement milling to achieve minor surface grade correction, and overlaying the runway surface with two inches of P-401 HMA pavement.
P-401 HMA Surface Course. Airport pavement design of HMA surface courses is outlined within the Advisory Circular AC 150/5370-10E Part V. The mix consisted of a #7 stone, #8 stone, #9 stone, #10 screenings, and bag house dust. Also, the asphalt binder was a PG 64-22. P-401-1 5/09 ITEM P-401 PLANT HOT MIX ASPHALT PAVEMENT (This Section may be replaced with Special A 16 by designer) DESCRIPTION. 401-1.1 This item shall consist of a surface course composed of mineral aggregate and asphalt cement mixed in a central mixing plant and placed on a prepared course according to these Specifications and shall Hot-Mix Asphalt (HMA) 101 Description: Understanding the basics of hot-mix asphalt – its composition and the importance of proper transporting, placement and compaction – is a vital necessity for anyone involved in the construction or inspection of asphalt pavements. Guidelines for Use of Highway Specifications for HMA Airport Pavements. Airfield Asphalt Pavement Technology Program (AAPTP) Project 06-05 called for the development of guidelines to be used by practicing airport pavement design engineers on the utilization of state highway hot mix asphalt specifications for use in airport pavements. Quality Control – HMA and PCC • QC is the responsibility of the contractor. • AC 150/5370-10F General Provision Section 100 requires a Contractor Quality Control Program when P-401 or P-501 is in the project. • Specification items P -401 and P-501 contain minimum items to be included in the Contractor Quality Control Program.
The HMA pavement at Taxiway Alpha of the Oceana Naval Air Station (NTU) in Virginia has been resurfaced approximately every eight to 10 years. The last resurfacing job was in 2000 where the middle 32 ft of the taxiway were milled and replaced with a 2.5-in. Navy airfield mix (almost identical to a P-401 HMA surface course) containing 20% RAP.
