Overview Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together. Our HMA is mixed at our asphalt production in HMA (P-401) as s tabilized base course + 6 in high quality. granular base (P-209) as s hown in Figure 2. The final thickness. for the base layer was defined for each case of analysis Behavior of P-401 HMA Surface in Accelerated Pavement Testing at High Temperatures and Tire Pressures Navneet Garg , Ph.D. , M.ASCE ; Hasan Kazmee , A.M.ASCE ; and Russell Knieriem Download SECTION 401 – QUALITY CONTROL/QUALITY ASSURANCE, QC/QA, HOT MIX ASPHALT, HMA, PAVEMENT 401.01 Description This work shall consist of one or more courses of QC/QA HMA base, intermediate, or surface mixtures constructed on prepared foundations in accordance with 105.03. 401.02 Quality Control P-401/P-403 HMA Base . 2,760 MPa (400,000 psi) P-501 PCC Surface . 27,600 MPa (4,000,000 psi) P-306 Econocrete Base . 4,830 MPa (700,000 psi) P-304 Cement Treated Base .
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.
