Bituminous mixture was prepared by using 80/100 Pen bitumen for control mix, while polyethylene modified mixture was prepared by blending linear low density polyethylene (LLDPE) with 80/100 Pen bitumen. The concentration of polymer in the blend was kept a

The effect of temperature on bitumen viscosity is significant and the same behavior is observed for mixtures with low n-heptane concentrations. Fig. 8 shows the impact of temperature on the mixture viscosities at 10 MPa. The mixture viscosities show a lin

Hot-mix asphalts are a mixture of suitable aggregate coated with asphalt cement. The term "hot-mix" comes from the process of heating the aggregate and asphalt before mixing to remove moisture from the aggregate and to obtain sufficient fluidity of the as

Asphalt is a combination of gravel and tar and is commonly used to cover driveways. Asphalt sees a variety of stains, especially those caused by leaking fluids from vehicles. Gas and oil are two common items that stain asphalt driveways. Not only will gas
