3. Tab.8.2.1 Relation between composite and property of asphalt name of composite physical property the effect to principal properties color state density(g/m ³ ) molecular weight oil component light yellow, liquid, 0.7 ～ 1, 300 ～ 500 red brown to make asphalt mobile asphaltic resin Yellow, semi-solid, 1.0 ～ 1.1, 600 ～ 1000 black brown to make asphalt adhesive, plastic and mobile asphaltene deep brown, solid, more than 1000, more than 1000 Black, powder to determine temperature stability and viscosity Composite The relation between composite and property of asphalt are shown in Tab.8.2.1

4. 2~3% of asphalt carbon and quasi-carbon compound is cracked in high temperature. It has the largest formula weight and can reduce the adhesive ability. Paraffin: It can reduce the adhesive ability, plastic properties and temperature stability. Solutions, such as salt curing to treat oil with much paraffin, can enhance soften point, reduce penetration degree, improve properties. Other Components
