Unformatted text preview: VERTICAL STRESSES IN THE PAVEMENT EFFECTS OF WHEEL LOAD ON VERTICAL STRESSES IN THE PAVMENT EFFECTS OF MIX PROPERTIES ON ASPHALT PAVEMENT PERFORMANCE (1) Marshall Stability- Related to tensile strength- Not directly related to shear strength or rutting resistance. (2) Marshall Flow- Excessive high Marshall flow is related to tender mix with low resistance to rutting- Mix with low Marshall flow is stiff and difficult to compact (3) VMA (Voids in Mineral Aggregate)- Low VMA is associated with bleeding and rutting problems. (4) Air Voids Content- Low air voids is associated with low VMA.- High air voids will cause reduced durability (increased asphalt hardening rate, increased water susceptibility, reduced fatigue and shear resistance). (5) Hveem S Value- Related to shear strength and rutting resistance (6) Tensile Strength- Related to cracking resistance (7) Shear Strength- Related to rutting resistance...
