Many construction processes are controlled by comparing the desired product, conceived during design, to the product produced during construction. The asphalt pavement construction process is often controlled in this manner. Control is often based on testing of components and assemblies of materials, the construction process, and the finished asphalt pavement. The success of the asphalt pavement construction project is usually judged based on how well test results produced during construction compare with criteria considered representing the desired product conceived during design.

Gilsonite has been the subject of exhaustive study to improve characteristics for use in paving. Various properties of asphalt are manipulated to produce a product that has the appropriate wear properties, rut resistance, fatigue and low temperature cracking resistance, adhesion strength, viscosity and pour point. Rut resistance is resistance to longitudinal surface depressions in the wheel paths. Adhesion strength is the maximum adhesion strength of the joint sealant and the joint reservoir, including but not limited to, between the aggregate and the binder.
Crack sealer produced by the blend of bitumen with SBS, Gilsonite, rubber process oil, crumb rubber in special temperature and pressure and using as sealing cracks and joints in the asphalt pavement and parking also cement pavement. It is used to seal expansion and longitudinal and transverse crack and construction joints between concrete and asphaltic shoulder. Gilsonite is one of the environmentally friendly products to repair and seal the asphalt. Gilsonite joint sealer and crack sealer is widely used in the world. The preferred embodiment of the invention employs a roofing adhesive or cement for filling the parking lot crack, either asphalt or concrete after it has been thoroughly cleaned either with air or water. The adhesive is preferably a modified bitumen rubber asphalt normally used for bonding roofing materials.
