Construction asphalt prepared by chemical treatment of deoiled asphalt

The 30# construction asphalt was prepared by chemical condensation of deoiled asphalt (DOA) from vacuum residue propane deasphalting in this study. It decreases the penetration and improves the softening point of DOA effectively based on the chemical condensation technology from experimental results. The group components of DOA were regulated through the addition of furfural extract oil dewaxed oil (DWO) with high content of aromatic components. Therefore, the ductility of condensed asphalt still meet the requirements of construction asphalt in the condition of decreased penetration and increased softening point. The 30# construction asphalt satisfies the standard requirements of the GB/T494-2010 by chemical condensation technology through the effective control of condensation degree with the appropriate blending proportion of DWO. The binary linear mathematical models of the properties of condensed asphalt have been established by regression analysis of the experimental data. This model had the high accuracy and excellent practical values. The properties of condensed asphalt could be accurately predicted and the construction asphalt production cost could be reasonably controlled. In addition, there was little change in the softening point of the construction asphalt pre and post thermal storage, which illustrated that the 30# construction asphalt obtained by chemical condensation of DOA has good thermal storage stability.

Properties of asphalt binder and asphalt concrete containing waste polyethylene

In this study, the effects of addition of waste polyethylene on asphalt binder and asphalt concrete mixture properties were studied. Four asphalt concrete mixtures (each mixture containing different percentages of shredded polyethylene material) were prepared and tested as per Indian specifications. Shredded polyethylene and hot asphalt binder were added to heated aggregate (in same sequence) until all aggregates were coated. The loose mixtures were compacted and tested for its mechanical and volumetric properties. Furthermore, compacted specimens were aged for short- and long-term conditions. The extracted binder from the aged and control mixtures was tested for its rheological properties using a dynamic shear rheometer. Mixtures containing shredded polyethylene showed improvement with respect to the Marshall strength, flow, and volumetric properties. The properties of recovered asphalt binder indicated that the addition of polyethylene improved complex modulus values and decreased phase angle values over range of frequencies.

Preparation and evaluation of 30# hard grade asphalt

The preparation and evaluation of 30# hard grade asphalt by blending softening point hard deoil asphalt with several soft components were investigated. The results showed that the properties and proportions of blending soft components had a great influence on the properties of 30# asphalt. Chunfeng 70# asphalt and Maoming deoil asphalt were more suitable as blending soft components and their blended asphalt met the technical requirements of GB/T 15180-2010 when the proportion of hard deoil asphalt were 6–12% and 8–16%, respectively. PG grade results indicated that dynamic modulus of 30# asphalts at high temperature increased significantly, and antirutting ability was also improved notably, while the bending resistant ability at low temperature was slightly inferior to the high-grade asphalt. The results of mix performance tests showed that 30# hard grade asphalt had excellent anti–high-temperature deformation ability and preferable water stability compared with high-grade asphalts.
