Crack sealing machine consists of two separate independent primary machine systems which refers to address longitudinal and general cracks. The longitudinal crack sealing system operates off the side of the machine and addresses cracks and joints at the edge of the lane that run with the direction of travel ,e.g. construction joints, whereas the general crack sealing system operates off the rear of the vehicle to address cracks that run generally across the pavement, e.g. random or transverse cracks and joints.
The crack sealing machine has been developed in a modular manner. The component subsystems independent to run; they can operate independently. This has allowed for rapid prototyping as well. In addition, this implies that the end user can tailor the set of components to best meet their crack and joint sealing methods. Furthermore, the two main systems share many of the same components, which reduces the need for component inventory, reduces the need for training of various components, and simplifies machine maintenance.
