The loss of concrete material from the pavement surface, resulting in a hole. Spalls are typically caused by weak concrete material, incompressible material in joints or cracks, and freeze-thaw cycles. B.07 Rigid Pavement Repairs Using Asphalt Materials . Asphalt plant mixed material may be used for many surface repairs to rigid pavement. They will
Asphaltenes comprise 5–25% the composition of bitumen, and in terms of building, a combination of compressed aromatic rings with aliphatic lateral chains and the number of aromatic rings is 6–20 and even sometimes more of this. Asphaltene rate in bitumen has many effects on rheological properties of bitumen.
Asphalt pavements and construction and demolition wastes are among the primary sources of reclaimed aggregates. The recycled material is first extracted from its source, processed, and then made suitable for further pavement construction utilization.

The existing methods for increasing the adhesive properties and roughness of asphalt concrete pavement are based on the use of mixtures of stone materials with bitumen or the construction of a layer of stone mastic asphalt (SMA). Nevertheless, they do not always ensure the standard adhesion coefficient after the first year of maintenance.
A new type of plastic and basalt fiber composite (PB) modifier, which is composed of waste plastic and basalt fiber using a specific process, was used for bus lanes to address severe high-temperature deformation diseases due to the heavy loads of buses. ... the actual over-loaded axle made the pavement structure of the bus lane suffer a 30% ...
Asphalt pavements are distinguished and categorized one of three ways: • By where they go and what they do (Surface, Binder, Base, Open Graded, Patch, etc.) • By the type of liquid asphalt that is used to make the mix (AC20, PG- - 64-22, etc.) • By maximum nominal size aggregate (1", 19 mm, etc.)
