The elastic modulus of asphalt is a key performance indicator in how asphalt will perform under wheel loading. When utilized in the mechanistic design procedure, a performance factor 'k' is adopted which incorporates two factors, including a) asphalt moduli and b) the percentage bitumen or binder in the mix.

Epoxy pavement markings are durable markings recognized for exceptional durability on asphalt and concrete surfaces alike. This exceptional durability is a result of tight bonding to the pavement surface that results from the chemical reaction that occurs when the two components are mixed.

There are four major categories of common asphalt pavement surface distress: Surface defects Raveling, flushing, polishing.
necessary to complete the construction of hot mix asphalt concrete pavement consisting of one or more courses on a previously prepared base, seal coat of asphalt cement and cover aggregate, and bituminous surface treatment in single or multiple courses.
The evolution of the straight edge for testing pavement has roots in highway construction where smoothness affects the ride quality. Cars have suspension systems that dampen road roughness. Aircraft suspension systems are not designed to absorb pavement roughness but to absorb the energy of landing impact.

The goal is to re-establish the pavement edge for the safety of the traveling public. Promote good drainage along the edge of the road. Make sure that surface water will run to the nearby ditch, and not pond along the pavement edge.
Pavement Joints: Both asphalt and Portland cement concrete pavements are constructed with joints as a part of the paving process or as expansion/contraction joints.
