Transverse Joints in Asphalt Pavement
Transverse joints are formed either at the beginning or the endpoint of an asphalt pavement and are perpendicular to the direction of the pavement. Transverse joints are unavoidable at some point of pavement construction due to unexpected working conditions. But ...
How to Construct Longitudinal Joints in Asphalt Pavement?
Longitudinal joints are joints formed during hot mix asphalt (HMA) pavement construction. These joints are formed when a new lane of hot mix asphalt pavement is placed adjacent to a previously placed lane. An improperly constructed longitudinal joint forms the ...
How does Improper Drainage Affect Asphalt Pavement?
A proper drainage system and its regular maintenance determine the longevity and stability of the asphalt pavement. On the other hand, improper maintenance of the pavement drainage system leads to eventual pavement deterioration, which results in huge repair and replacement ...
Alligator Cracking in Asphalt Pavement: Causes and Control
Alligator cracking is an interlaced cracking pattern observed on the asphalt pavement surface due to repeated traffic loading. Alligator cracks cause deterioration of asphalt pavement and resemble the scales on an alligator’s back. This article explains the leading causes and ...
