As A Result Of Cracks And Turning The Asphalt Road Into A Hole

Asphalt is a hydrocarbon adhesive material, brownish brown, waterproof, and visoelastic. Asphalt is often also called bitumen is a binder on the asphalt mixture used as a layer of flexural surface of the pavement. Asphalt comes from nature or from petroleum processing.

Asphalt or asphalt is a viscous liquid which is a hydrocarbon compound with little sulfur, oxygen, and chlorine. Asphalt as a binder on flexible pavement has viscoelastic properties. Asphalt looks solid at room temperature but is a very thick liquid. Asphalt is a very complex material, and is chemically characterless. The main content of asphalt is a saturated, unsaturated, aliphatic, and aromatic carbon compound having up to 150 carbon atoms per molecule. Atoms other than hydrogen, and the carbon that also forms asphalt are nitrogen, oxygen, sulfur, and some other atoms. Quantitatively, typically 80% of the asphalt mass is carbon, 10% hydrogen, 6% sulfur, and oxygen remaining, and nitrogen, as well as a number of iron, nickel, and vanadium minerals. These compounds are often described in asphalten (small molecular mass), and malten (many large molecules). Usually asphalt contains 5 to 25% aspalten. Most of the compounds in asphalt are polar compounds.

Economic activity is strongly supported by the availability of road infrastructure. Good roads facilitate relationships between different regions. Conversely, a damaged road will certainly hinder economic activity and could be the cause of accidents. Road damage is one of the most common problems in Indonesia, especially in roads with heavy traffic volume. The following types of asphalt road damage, its causes and solutions.

Fatigue and deformation of all asphalt layers. Types of asphalt road damage in the form of cracks and cracked deformations in almost all roads can be found, especially in interprovincial roads. The cause is none other than heavy vehicles that pass like buses and trucks. Heavy vehicle loads produce each layer of pavement strain and voltage occurs. The passing vehicle burden ends up causing cracks and tired deformations.

If the crack is tired and the deformation is let go, then when the rainy season can be sure the water will go into the cracks and change the cracks into larger holes. Therefore, for fatigue and deformation cracks to occur, repairs must be made with patches.

Roads with asphalt pavement are not really suitable for heavy vehicle types. Heavy vehicles should be directed to cross concrete roads that have stronger structures than roads with asphalt pavement.
